The Sinopec project undertaken by the School of Chemical Engineering of East China University of Technology, a one-step process for the production of dimethyl ether from a three-phase bed syngas, after three years of collaborative research, has made one step synthesis of dimethyl ether from syngas in China reach the advanced level of similar international research. The process has passed the expert appraisal hosted by Sinopec.
One-step syngas synthesis of dimethyl ether is a new production process being researched and developed at home and abroad. The school's Dingye, Ying Weiyong and other professors conducted a one-step process for the synthesis of dimethyl ether in a three-phase slurry bed through a 0.5-liter stirred tank experimental study. The new process uses a unique mixed catalyst and inert liquid heat carrier, and studies the reaction conditions, macro-kinetics, and the gas-liquid equilibrium of the reactants and solvents, and establishes a mathematical model of the three-phase slurry bed reactor. Based on the study of the phase equilibrium of the reaction system, the simulation and analysis of the whole process of the reaction and refining were carried out, and the complete basic data and engineering data were provided for the industrial device. An innovative "one-bed, three-tower, double-return" process was proposed, and a technological package for one-step production of dimethyl ether from synthetic gas in a three-phase slurry bed with an annual capacity of 30,000 tons was prepared, and an industrial testing device for 10,000 tons of dimethyl ether was constructed. Instructive.
