Noble metal catalysts may be attractive for hydrotreating of catalytic fast pyrolysis (CFP) oils. Model mixtures of raw noncatalytic fast pyrolysis and CFP oils representative of upgrading over HZSM-5 were hydrotreated in a batch reactor at 250–360 °C with palladium/carbon catalyst and 100 bar (cold) of hydrogen. The CFP oils gave high carbon yields of >95%, consumed less hydrogen per gram of oil produced, and had lower final oxygen concentrations than the raw oils did. GC/MS results were consistent with hydrogenation of alkenes and some oxygen-functionalized aromatic rings (e.g., phenolics) followed by hydrodeoxygenation at 360 °C. Complete deoxygenation was not obtained, and higher temperatures are recommended. The model oils’ chemical transformations, carbon yields, and deoxygenation were similar to those of oils produced in a bench-scale reactor with HZSM-5 catalyst.

Pd / C上模型混合物和催化快速裂解油的加氢处理

贵金属催化剂可能对催化快速热解（CFP）油的加氢处理具有吸引力。代表通过HZSM-5进行升级的原始非催化快速热解和CFP油的模型混合物在间歇反应器中于250-360°C下用钯/碳催化剂和100 bar（冷）氢进行加氢处理。CFP油的碳产率高出95％，每克油所消耗的氢较少，最终氧浓度比原油低。GC / MS结果与烯烃和一些氧官能化的芳环（例如酚醛）加氢，然后在360°C进行加氢脱氧相一致。无法完全脱氧，建议使用更高的温度。模型油的化学转化，碳收率，
