Feedstocks primary biomass derivatives

Generally, two types of biomass resources can be considered in the discussion on renewable energy feedstock (1) primary biomass, such as energy crops, including switchgrass, poplar, and willow, and (2) biomass residues (primary when derived from wood or processed agricultural biomass secondary when derived from food or fiber processing by-products, or animal waste and tertiary when derived from urban residues).21... 

The primary product is fuel-grade, coal-derived gas which is similar to natural gas. The basic gasification process can also be applied to other carbon-based feedstocks such as biomass or municipal waste.

Alkanes are the primary feedstock from which the majority of the world s chemicals are derived. They are the primary constituents of petroleum and natural gas and the associated low boiling components of natural gas. Coal, natural gas, and biomass are also sources of alkanes produced via gasification of these materials to syngas (CO/H2) followed by Fischer-Tropsch catalysis resulting in a stochastic distribution of Unear hydrocarbons.
