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.

Phase change thermal control materials rely on solid-liquid or solid-solid phase change processes to absorb and release latent heat, enabling the storage and transport of heat under near-constant temperature conditions. They are key functional materials in fields such as building energy conservation, industrial waste heat utilization, cold chain transportation, and thermal management of electronic devices. This technology focuses on the formulation and preparation of phase change thermal control materials. Through coordinated design of base material selection, phase change temperature range control, packaging and molding, and heat transfer enhancement, the products have high phase change enthalpy, low supercooling, and good cycle stability, and can be customized according to application scenarios in terms of phase change temperature and form (molded plates, microcapsules, composite blocks, etc.).

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.

The water washing-distillation technology for ammonia-containing waste gas recovery: After the ammonia-containing waste gas is filtered and pre-cooled, it enters a multi-stage countercurrent water absorption system to obtain 18% to 22% concentrated ammonia water; the ammonia water is sent to the distillation tower for heating and absorption, and the high-purity ammonia gas at the top of the tower is compressed and condensed to produce industrial liquid ammonia products; the absorption water is recycled, and the deammonization exhaust gas is treated with water after purification to meet emission standards. This technology combines waste gas treatment with product recovery, solving the ammonia emission problem and producing marketable liquid ammonia or ammonia water products, which is suitable for the treatment of ammonia-containing exhaust gas from coking, synthetic ammonia, urea, and nitric acid plants.
