OP-II-3

PP-I-47The basic side reaction is reception of methane on Fisher-Tropsh reaction onmetal centers of the Zn-Cu-Al-catalyst dynamically arising while in service:Other collateral reactions, such as production of dimethyl ether and heavy spirits,are also considered in mathematical model, though amount of products of thesereactions is low.The purpose of this work was creation of adequate mathematical model ofmethanol synthesis, the considering mechanism of course of reactions on surfaces ofthe catalyst and the main diffusion resistance. Creation of model has been dividedinto four stages – by numbers of shelves in a reactor – in view of greater deactivationof the catalyst on the first shelf.This mathematical model allows to accurately predict activity and selectivity of thecatalyst during its operation, to select optimum modes for the most effective and longoperation of the catalyst. It also allows to select for any plant of methanol synthesis themost suitable catalysts of various manufacturers providing a high yield of an endproduct.As a result a selection of the optimum catalyst and a mode of its operation willlead to more effective work of installation and to reduction of the cost price of methanol.References[1].
