The removal of oxygen, typically as CO and CO 2, reduces the yield of fuel products, as carbon is 'lost' to these gases rather than captured in valuable liquid reaction products (reactions 2 and 3). In contrast, hydrodeoxygenation requires an external source of hydrogen (reaction 4). Earlier work ranked the various likely lipid / biomass feedstocks on a staircase based on their effective H .

From the perspective of chemical engineering reaction, the pyrolysis process is believed to proceed via two-step reactions: the primary free radicals reaction and the secondary volatiles reaction in a large-scale reactor, as shown in Fig. 1a. The primary reaction begins with the formation of free radicals through the breakage of weak bonds in coal and ends with the stabilization and .
