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.
