General description

Methanol is an organic solvent that can be synthesized from syngas in the presence of CuO/ZnO/Al2O3 catalysts.[5] It is an ideal candidate as a hydrogen source in fuel cell technology due to its high H/C ratio, low propensity for soot generation, relatively low reforming temperature and as it exists in liquid state at room temperature.[6][7] In a direct methanol fuel cell (DMFC), methanol undergoes oxidation with air to generate electricity. The olefins (ethylene or propylene) formed from methanol via MTO (methanol-to-olefins) process, can be an alternative to oil and gas to produce hydrocarbon fuels.[8]

Methanol undergoes thermochemical conversion to C2-C10 hydrocarbons in the presence of shape-selective zeolites has been reported.[1] Its oxidation on Ru-Pt catalyst system by ruthenium ad-atoms has been proposed.[2]

Application

Methanol has been used as a solvent for the sodium dodecyl sulfate-polyacrylamide gel electrophoretic (SDS-PAGE) analysis of alkaline protease isoforms isolated from larva of the spotted sand bass (Paralabrax maculatofasciatus).[3] It has been used in the isolation and quantitative determination of carotenes and xanthophylls from Capsicum annum pericarp extracts by HPLC.[4]
