Pyrolysis oils Draft Regulatory Impact Analysis: Changes to Renewable Fuel Standard Program Pyrolysis Pyrolysis oils, or bio-oils, are produced by condensing the decomposed biomass instead of introducing a gasifying agent.279 The decomposition occurs at lower temperatures than gasification processes, and produces liquid oil instead of a synthesis gas. The reaction can occur both with or without the use of catalysts. The oil produced varies in oxygen content or viscosity according to the feedstock used. The oil must have particulates and ash removed in filtration to create a homogenous product and is further upgraded to hydrocarbon fuels via hydrotreating and hydrocracking processing, which reduces its total oxygen content. Some believe that pyrolysis could have a significant economic advantage over other cellulosic ethanol approaches since very little has been done in terms of optimizing the process, and as such, there are still many possibilities yet to be explored.280 epa.gov
