Synthesis Methanol Catalyst

Low-pressure methanol synthesis catalyst scst-253 is a kind of cu-zn-al based methanol synthesis catalyst for using coal, oil field gas, refinery gas, coke oven gas, naphtha, natural gas or oil as it’s feedstock. The synthesis plant pressure is3~8mpa.
The main reactions are as follows:
co + 2h2→ ch3oh+ 90.69 kjmol
co2 + 3h2→ ch3oh+h2o + 49.53 kjmol
