Abstract
The results of study of catalytic vacuum gas oil oxycracking process in presence of metal zeolite catalysts are presented. Screening of oxides of 10 modifying transition metals (Cu, Ti, V, Cr, Fe, Co, Ni, Cd, Mo, and W) made it possible to disclose the basic differences in the behavior of the catalytic systems. Based on the data obtained, an activity series were constructed (based on the total yield of light fractions): Mo > Ti > Cr > Ni > Fe >W > V > Cd > Co > Cu. Best results for the target fractions were obtained in the presence of molybdenum, titanium, and vanadium zeolite systems (for 195/200-300°C fractions) and for tungsten-containing system (for hydrocarbon gas). Comparison of vacuum gas oil conversion data obtained under catalytic oxycracking conditions with bond strength of the surface oxygen of the metal oxides made it possible to establish their correspondence and to recommend this criterion for choosing catalysts for the process.
本文介绍了在金属沸石催化剂存在下催化真空瓦斯油氧裂解过程的研究结果。对 10 种改性过渡金属（Cu、Ti、V、Cr、Fe、Co、Ni、Cd、Mo 和 W）的氧化物进行了筛选，从而揭示了催化体系行为的基本差异。根据所获得的数据，构建了一个活性系列（基于轻馏分的总产率）：Mo > Ti > Cr > Ni > Fe > W > V > Cd > Co > Cu。钼、钛和钒沸石系统（用于 195/200-300°C 的馏分）和含钨系统（用于碳氢化合物气体）在目标馏分方面取得了最佳结果。将催化氧裂解条件下获得的真空瓦斯油转化数据与金属氧化物表面氧的结合强度进行比较，可以确定它们之间的对应关系，并建议在选择工艺催化剂时采用这一标准。
