Can GE gas be directly used to produce methanol after desulfurization?
Thread Content
For the GE gasifier, the composition of the gas at its outlet is as follows: CO 46.5%, H2 35.5%, CO2 17.67%, CH4 0.05%, N2 0.27%, and H2S 0.01%. Can this gas be used directly in methanol production after desulfurization (note: there is no recycling process; the separated gas is used in the next processing step?), or are there any other ways to produce methanol without going through a shift reaction process?
That probably won’t work! A too low hydrogen-to-carbon ratio fails to meet the requirements for methanol production, and it is fatal to synthetic catalysts!
The existing catalyst needs to be replaced. What is the pressure in the downstream section? Without a circulation system, there is no compressor, and the heat generated by the catalyst cannot be removed through a large volume of circulation, resulting in rapid thermal aging.
