1 PagesDemonstrating Long-Term Hydrotreatment Catalyst Performance Challenge Pyrolysis bio oil feedstock is one of the most difficult precursors in the world to convert to bio-based fuel. Because pyrolysis uses heat to break down biomass, the resulting oil contains high levels of oxygen and acids and is unstable at the high temperatures used in refinery processing. The instability makes conversion into hydrocarbon fuels more difficult and causes the catalysts to be degraded more quickly. This accelerated catalyst degradation can make bio-oil conversion prohibitively costly compared to conversion of petroleum-based oils. Solution As part of a DOE-sponsored project, Battelle and Pacific Northwest National Laboratory (PNNL) developed a novel catalyst for conversion of pyrolysis bio oil feedstock. Th
