【Abstract】 A quasi-homogoneous one-dimensional model of methanol synthesis is established for the four-stage adiabatic fixed bed and interstagc cold shot reactor. Based on this mathematical model, simulations are carried out on a digital computer. During the simulation, keeping the quantity of raw materials fixed we change the inlet temperature of each stage so that fraction of the cold shot material quantiy of each stage varies. In this way, various temperature and concentration profiles of stage beds as well as the output of methanol are obtained. According to the simulation results, the relation between the output of methanol and the iniet temperature of each stage is established, which is called the methanol output model.更多还原
