Climate change and the unsustainability of fossil fuels are calling for cleaner energies such as methanol as a fuel. Methanol is one of the simplest molecules for energy storage and is utilized to generate a wide range of products. Since methanol can be produced from biomass, numerous countries could produce and utilize biomethanol. Here, we review methanol production processes, technoeconomy ...

In pyrolysis, lignin, cellulose, and semicellulose, the main com ponents of biomass are quickly thermochemically decomposed in seconds to form smallmolecule compounds, in which about 50% of the volatiles can be condensed to form biooil. The carbon content of biooil ranges from 30 to 50%, and the high heating value (HHV) is about 15 MJ kg−1.

Biocoal is produced by processing dry biomass in an inert environment (no oxygen) at high temperatures, a process referred to as pyrolysis. Depending on the temperatures and the characteristics of the end product, the process may also be referred to as torrefaction. This process is commonly carried out using an indirectfired rotary kiln.
