Hydrodeoxygenation (HDO) of liquid phase pyrolysis oil with high water content was performed continuously in a plug flow reactor on a sulfided CoMo/Al₂O₃ catalyst under a hydrogen pressure of 120 bar at 400 °C. The intention of this project was to achieve fuels of diesel, kerosene and gasoline quality from liquid phase pyrolysis oil (LPP oil). The liquid hourly space velocity (LHSV) was altered between 0.5 h⁻¹ and 3 h⁻¹. The LHSV was higher than those reported for state-of-the-art HDO processes. The LPP oil was derived from the bioCRACK pilot plant in the OMV refinery in Vienna/Schwechat, which was operated by BDI – BioEnergy International GmbH. After HDO, separation of the upgraded hydrocarbon fraction from the aqueous carrier was achieved. About 50% of the biogenous carbon was transferred into the liquid hydrocarbon product phase, and the residual amount was transferred into the gas phase. Comparably slow catalyst aging by coke formation was attributed to the high water content of LPP oil. During HDO, a fuel of almost gasoline and diesel quality was produced. The H/C ratio was between 1.7 and 2 with a residual oxygen content of 0.0 wt% to 1.2 wt%. The boiling range of the hydrocarbon product phase was between those of gasoline and diesel. In GC-MS analysis, mainly saturated alkanes were found.

液相热解油的高通量连续加氢脱氧

具有高水含量的液相热解油的加氢脱氧（HDO）在活塞流反应器中在硫化的CoMo / Al ₂ O ₃催化剂上在120 bar的氢气压力下于400°C连续进行。该项目的目的是从液相热解油（LPP油）中获得柴油，煤油和汽油的质量。液时空速（LHSV）在0.5 h ^-1和3 h ^{-1之间变化}。LHSV高于最新的HDO流程所报告的LHSV。LPP油来自BDI – BioEnergy International GmbH经营的位于维也纳/ Schwechat的OMV精炼厂的bioCRACK中试厂。HDO之后，实现了从水性载体中分离出提质的烃馏分。大约50％的生物碳转移到了液态烃产物相中，剩余量转移到了气相中。相比之下，由于焦炭形成而导致的催化剂老化较慢归因于LPP油的高水分含量。在HDO期间，生产了几乎汽油和柴油质量的燃料。H / C比在1.7至2之间，残余氧含量为0.0重量％至1.2重量％。烃产物相的沸程在汽油和柴油的沸程之间。在GC-MS分析中，
