1,2-Dichloroethane is a key intermediate in the VCM/PVC industry chain, and the traditional route relies on the direct chlorination or oxidation of ethylene. This technology has opened up a new route for the production of 1,2-dichloroethane from ethylene glycol, in which the two hydroxyl groups of ethylene glycol are converted into chlorine atoms through chlorination substitution, resulting in the target product. This route provides a pathway for the enrichment of ethylene glycol production capacity (especially coal-based ethylene glycol) to the downstream chlor-alkali-PVC industry chain, and also provides an alternative raw material option for ethylene resource-constrained owners. The raw material route is flexible and can be directly connected to existing VCM cracking to chlorine ethylene units. The technology has been built and commissioned in a pilot plant, which has verified the feasibility of the process and has the basis for process scaling. The service provided includes process package authorization, raw material adaptation evaluation, basic design support, corrosion-resistant equipment selection recommendations, commissioning guidance, and operation training, and the owner needs to provide a chlorine source and corresponding utilities.

The catalyst stability directly determines the operating cycle and economic efficiency of the methanol oxidation to formaldehyde plant. Molybdenum migration loss and surface carbon are the two main causes of the catalyst deactivation. This technology starts from the catalyst formulation and structure, and through the adjustment of additives and optimization of the preparation process, it strengthens the fixation of molybdenum species, improves the distribution of acid and alkali on the surface, significantly slows the loss of active components and the rate of carbon deposition, extends the catalyst service life, stabilizes the formaldehyde yield, and reduces the frequency of shutdown and replacement and the unit cost. The anti-deactivation catalyst is compatible with the existing industrial installations using the iron-molybdenum method, and no large-scale modifications are required to replace it. The technology has been built and commissioned in a pilot plant, which has verified the performance of the catalyst and the feasibility of scale-up production, and has the basis for process scale-up. It is suitable for formaldehyde production enterprises and catalyst manufacturers. It can provide catalyst product technology authorization, preparation process support, filling and operation scheme design, deactivation diagnosis, and service recommendations for life management.

0
This technology is aimed at the recovery and reuse of iron-molybdenum catalysts that have become inactive due to factors such as molybdenum volatilization and carbon accumulation. By separating the components of the catalyst and chemically regenerating them, effective components such as molybdenum and iron can be recovered and the catalyst's activity can be restored or partially restored. The regenerated catalyst can be downgraded or reused in proportion to industrial installations, while the recovered metal components can be used as raw materials in the production of new catalysts, achieving a resource closed loop and reducing the amount of hazardous waste disposal and the cost of purchasing fresh catalysts. This technology has been built and commissioned in a pilot plant, which has verified the feasibility of the process and has the basis for process scaling. It is suitable for methanol production enterprises and catalyst recovery and treatment service providers. It can provide license for the recovery process, design support for regeneration plants, operation diagnosis and operation training, and other services.

High-concentration formaldehyde is an important raw material for synthetic resins, engineering plastics, and a variety of fine chemicals. The traditional methanol oxidation method is limited by equilibrium and by-product water, making it difficult to directly obtain high-concentration formaldehyde and requiring high energy consumption for concentration. In this technology, dimethyl ether is used as the raw material for catalytic oxidation, with less water introduced in the reaction pathway, which can directly produce high-concentration formaldehyde products, significantly reducing the energy consumption and equipment investment required for subsequent dehydration and concentration. Dimethyl ether can be conveniently produced from methanol dehydration, and the raw material route is smoothly integrated with existing coal chemical and natural gas chemical industry chains. This technology is suitable for extending from areas with abundant methanol production capacity to downstream facilities, as well as for facilities with high formaldehyde concentration requirements, such as polyformaldehyde. At present, a pilot plant has been built and commissioned, verifying the feasibility of the process and providing the basis for process scaling. The company can provide process package licensing, catalyst and reactor selection recommendations, basic design support, commissioning guidance, and operation training services, with the customer needing to provide either methanol or dimethyl ether as the raw material.

Acetyl acetate is a widely used green solvent. The traditional esterification route requires two steps of acetic acid and ethanol as raw materials, with a long process and high energy consumption. This technology uses ethanol as a single raw material and converts it into acetyl acetate in one step under the action of a specialized catalyst, while simultaneously producing hydrogen gas. The process route is short, the atom economy is high, and there are no problems with corrosion and waste liquid caused by strong acid catalysts. The hydrogen gas produced can be reused in the plant's hydrogenation equipment or as an energy product, thereby improving the overall economy. This route is particularly suitable for owners with abundant ethanol resources (biological ethanol or synthetic ethanol) and a demand for acetyl acetate, enabling a single plant to produce two products. The technology has been built and commissioned in a pilot plant, which has verified the feasibility of the process and has the basis for process scaling. The owner needs to provide the necessary conditions for the supply of ethanol raw materials and product storage and transportation.

Using agricultural and forestry waste and other plant solid waste as raw materials, and coupling them with water to produce green hydrogen is a new approach that combines biomass resource utilization with green hydrogen production. Through thermal chemical or catalytic conversion processes, the carbon-hydrogen components in plant solid waste are converted together with water to produce hydrogen-rich gases, which, after conversion and purification, yield high-purity hydrogen gas. This not only disposes of dispersed biomass resources such as straw and wood chips, but also produces zero-carbon hydrogen energy products. By-product gases and residues can be further utilized in a comprehensive manner, achieving a closed resource cycle. This approach provides a new option for hydrogen production in regions where there is a lack of cheap wind and solar power but abundant biomass resources, and it can be coupled with existing biomass energy parks. The technology has been built and commissioned in a pilot plant, which has verified the feasibility of the process and has the basis for process scaling up. It is suitable for parks and energy enterprises with stable biomass raw materials. We can provide process package licensing, raw material pretreatment solutions, basic design support, commissioning guidance, and operation training, among other services. The owner needs to address the storage, transportation, and utility engineering aspects of the raw materials.

In response to the increasingly stringent control of short-chain chlorinated paraffin by the international community, the control of short-chain content in medium- and long-chain chlorinated paraffin products has become a hard indicator for industry access. This technology is aimed at this compliance requirement and takes a synergistic approach from both ends of the raw material wax distillation and fractionation and chlorination processes. By precisely controlling the carbon number distribution of the raw material, optimizing the temperature and mass transfer conditions of the chlorination reaction, and inhibiting the introduction and decomposition of short-chain components, the short-chain content in medium- and long-chain chlorinated paraffin products can be stably controlled to meet regulatory requirements. The products can be used as PVC auxiliary plasticizers, rubber and paint flame retardant plasticizers, metal processing fluid pressure agents, and so on. The technology has been built and commissioned in a pilot plant, which has verified the feasibility of the process and has the basis for process scaling. It is suitable for paraffin chlorination production enterprises to upgrade their products and for enterprises planning to enter this field and target export compliance markets. Services such as process package licensing, raw material fractionation scheme design, basic design support, commissioning guidance, and operation training are available.
