Methanol: Weekly Topic – At what hydrogen-to-carbon ratio in the reactor is methanol production highest? 2015.10.26--11.02
The optimal hydrogen-to-carbon ratio for fresh air is around 2.05–2.15; a hydrogen-to-carbon ratio of 4–5 at the inlet to the tower results in higher methanol production along with fewer by-products (impurities). So it is generally kept within this range!
Hehe, maybe I accidentally typed an extra character while typing. . . . Made a common-sense mistake! ! It really shouldn’t be. :$
I see that in process packages, a hydrogen-to-carbon ratio of 10 is generally recommended in the initial stage, while 7 is recommended later on
Fresh gas: 1.95–2.15; for syngas, 4–8 per tower in a single-tower configuration, and 3–5 in a cascaded-tower process; 5–15 for two towers
Generally, the hydrogen-to-carbon ratio of fresh gas ranges from 2.05 to 2.15, while that of the gas entering the tower ranges from 3.97 to 6
