In response to the structural contradiction between the abundance of propane resources and the shortage of light cracking feedstock, this technology selectively converts propane into ethylene and propylene through catalytic conversion. The reaction process realizes the directional restructuring of C4 alkanes into light hydrocarbons, and the products, ethylene and propylene, are high-quality feedstock for steam cracking units, significantly improving the yield of ethylene and propylene and improving the structure of the cracking feedstock. Compared with direct cracking of propane, this route better matches the design of cracking furnaces using ethylene and propylene as the main feedstock. This technology provides a path for owners with propane resources (refineries, LPG trading, C4 separation units) to upgrade to high-value light hydrocarbon products. A pilot plant has been completed and put into operation, which has verified the feasibility of the process and has the basis for process scaling. Services such as process package authorization, feedstock and product scheme design, basic design support, catalyst selection and operation management recommendations, driving guidance, and operation training are available.

This technology uses isobutane as raw material and converts it selectively into ethane and propane through a catalytic conversion process, achieving the reallocation of value for C4 resources: converting isobutane from refinery by-products or imported LPG into more in-demand light hydrocarbon cracking feedstock, matching directly with the feedstock of the cracking unit, thereby improving the overall ethylene yield and operating economy of the cracking unit. This technology provides a new tool for optimizing the feedstock structure for large-scale petrochemical bases with abundant C4 resources and either adjacent to or in close proximity to cracking units. The technology has been built and commissioned in a pilot plant, which has verified the feasibility of the process and laid the foundation for process scaling.

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 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 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.
