从木质纤维素生物质获得的液体的潜在的价值增值途径可以是它们与石油馏分共加氢处理以生产运输燃料。因此，在加氢处理条件下，生物质化合物通过HDO和脱羧/脱羧反应转化，导致产生CO、CO2和水。因此，在工业条件下工作的直馏瓦斯油（SRGO）转化中，考虑考克斯对HDT催化剂性能的影响似乎是必要的。SRGO的转化在330 ℃、LHSV = 1 h-1和5 MPa下在商业CoMo/Al 2 O3硫化催化剂上在各种浓度的考克斯（0.0 ≤ CO或CO2的摩尔流量≤ 13.4 mmol/h）存在下进行。考克斯的引入抑制HDS和HDN反应，并且在较小程度上抑制芳族化合物的氢化。水煤气变换和甲烷化反应与HDT反应竞争，甲烷是主要产物，WGS平衡控制剩余物的分配。
A potential valorization pathway for liquids obtained from lignocellulosic biomass could be their cohydrotreatment with petroleum cuts to produce transportation fuels. Thus, under hydrotreating conditions, biomass compounds are converted through HDO and decarbylation/decarboxylation reactions, leading to the production of CO, CO2, and water. Therefore, it seems essential to consider the impact of COx on the performance of an HDT catalyst in the conversion of a straight run gas oil (SRGO), working under industrial conditions. The conversion of the SRGO was performed at 330 °C, LHSV = 1 h−1, and 5 MPa on a commercial CoMo/Al2O3 sulfided catalyst in the presence of various concentrations of COx (0.0 < molar flow of CO or CO2 < 13.4 mmol/h). The introduction of COx inhibits the HDS and HDN reactions and, to a lesser extent, the hydrogenation of aromatics. Water gas shift and methanation reactions compete with HDT reactions, methane being the major product, and WGS equilibria govern the distribution of the rem...
