Abstract
The amount of renewable hydrocarbons produced from biomass may be increased by pyrolyzing the biomass in a biomass conversion unit in the presence of hydrogen sulfide or a sulfiding agent. The formation of deposits of unwanted carbonaceous materials, such as coke, is reduced by the presence of the hydrogen sulfide or sulfiding agent.
