Catalysts for the Methanol Synthesis (Fast Flow Treatment *)

Cataylsts used for pressure supported synthesis for methanol are well-known since many decades. The real performer however will never be described exactly. Normally one takes a certain amount of copper on to a zinc-oxide-to-alox matrix.
Yet particle size matters, either for copper and also for the other components used too. (The clue of the shaping factors!)
Our catalyst is placed in such a way and is of such a structure, that progress in synthesis in our reactors is due to a very fast sequence: the gas moiety moves along the catalyst with about sonic speed (in accordance and reduced to NPT conditions).
Carbon monoxide is mainly absorbed at the surface of the zinc oxide particles, where imperfections in the cristaline matrix are localized.
Hydrogen will be fixed mainly at the absorbed carbon monoxide itself. Thus the catalyst is to be saturated first with the monoxid component in subsequent adding hydrogen to start the reaction sequence.
* The fast flow (and the fast re-flow) treatment is a newer way on flash synthesis in small scale reactors, to furnish pilot-plants with analog product yields as bigger gear normaly do. However with fast recovery there are encompassed many more abilities and guidelines in newer synthetic routes to give faster and remarkable results. Especially the pass-throu times are exceptional, whereas treatments allow a maximum of almost sonic speed of the gasflow passing, calculated on NTP rule, to give the unique Fast-Flow-Reactor-Unit; F2RU.
