On November 21st, the Southwest Research & Design Institute of Chemical Industry took the lead in organizing the key projects of the national “Eleventh Five-Year Plan†scientific and technological support plan undertaken by relevant research institutes, universities and enterprises—two topics for the development of key technologies for the production of bulk chemicals from non-oil routes. , Accepted by experts organized by China National Chemical Corporation in Chengdu. The two topics are the key technologies for the development of acetylene/acrylic acid pilot plant technology for natural gas or coalbed methane production and the preparation of oxygenates for non-petroleum routes.
The research and development projects for the pilot test of acetylene and acrylic acid from natural gas or coal bed gas undertaken by the Southwest Institute of Technology, the Institute of Metal Research, Chinese Academy of Sciences and the Chengdu Branch of the Chinese Academy of Sciences, focused on the deoxidation process and catalyst for coalbed methane, and conducted a pilot test for the deoxidation of coalbed methane. Through on-the-spot assessment, the preparation of a low quality CBM purification and enrichment combination technology package was completed. This topic also broke through the key technologies of plasma control power amplification, completed the installation and testing of a 1,000 tonne/year microwave composite direct current plasma cracking methane-to-acetylene reactor, conducted a study on the separation and concentration of dilute acetylene, and a scale of 160Nm3/h. Trial work completed the concept design of the 10,000-ton industrial plant. In addition, the research group also optimized acetylene carbonyl synthesis of acrylic acid catalyst and reaction process, carried out a 1,000-ton/year pilot study, and completed the 10,000-ton process software package.
The key technical topics for preparation of oxygen-containing compounds on non-petroleum routes undertaken by Southwest Institute, East China University of Science and Technology, Shanghai Petrochemical Research Institute, Sichuan Tianyi Science and Technology Corporation, and Dalian Institute of Chemical Technology, Chinese Academy of Sciences, developed a methane-enriched gas self-thermal reforming synthesis gas catalyst. , Completion of the conversion process and conversion furnace simulation calculations, the preparation of the process software package; formulated the overall plan of the converter and the nozzle, completed the reformer cold mold test, the nozzle has been used in a number of companies; developed a one-step synthetic gas system two Methyl ether bifunctional catalyst, established the kinetic equations, and carried out the whole process simulation; built a 300 ton/year modified methanol-based dimethyl ether catalyst trial production line, and the catalyst product has been used on more than 40 sets of industrial devices to complete 1 million tons / Year design of methanol based dimethyl ether plant. In addition, they also completed the study of the kinetics of large-scale air-cooled-water-cooled tandem methanol synthesis reactors, established a mathematical model, compiled a reactor design software and process software package for producing 1 million tons of methanol per year, and developed a new type of methanol for CO2 production. High-efficiency catalysts have been developed for the new carbon dioxide-produced methanol process; fixed-bed and fluidized-bed methanol to propylene catalysts have been developed separately, and a synthetic propylene process pilot plant has been completed and a pilot plant has been completed.
In the course of the research, these two subjects applied for 43 invention patents and obtained 9 invention patent authorizations.
