Fuel grade and AA grade methanol are the two different forms of methanol available [57]. Converting glycerol to methanol is an appealing solution to the problem of excess glycerol.

Scientific editors of MDPI journals from around the world s largest exporter methanol. The water condensed out of the syngas as well as the hydrogen fuel produced from the PSA process were also considered as by-products from the process. In addition, a methanol production plant capacity of 6.8 tonnes/hr of crude glycerol feed for a 20-year plant life was investigated. From 2008 through 2035, global energy-linked CO2 emission is predicted to increase by 43% if petroleum-based resources are used [4]. Methanol cannot be produced when only H2 and CO are present in syngas, hence, Lcking [50] asserts that the hydrogenation of CO and catalytic hydrogenation of CO2 are necessary for its production.

One-column distillation is required for methanol of the fuel grade. The crude glycerol to methanol (CGtM) process can take several alternative courses, but the most common one involves two steps: glycerol reforming to syngas and methanol synthesis from syngas [3, 23]. Adeniyi and Ighalo [43] also verified that H2 production was favoured as the STR temperature increased up to a certain point. CO concentration at the reactor inlet is normally limited to about 10-15%, after dilution with recycled H2. Effect of STR temperature on the syngas composition at (a) SGR=6 (b) SGR=9.
