A single events microkinetic model for hydrocracking of vacuum gas oil [PDF]
Computers & Chemical Engineering, 2017 Abstract The single events microkinetic modelling approach is extended to include saturated and unsaturated cyclic molecules, in addition to paraffins. The model is successfully applied to hydrocracking (HCK) of an hydrotreated Vacuum Gas Oil (VGO) residue in a pilot plant, under industrial operating conditions, on a commercial bi-functional catalyst.

Molecular Transformation of Vacuum Gas Oil in Hydrodesulfurization.
Journal of The Japan Petroleum Institute, 1997 減圧軽油 (VGO) の市販脱硫触媒による水素化脱硫反応を, 高速液体クロマトグラフィー (HPLC)-電解電離質量分析 (FI/MS) 法を用いて, 化合物レベルで解析した。VGOおよびその脱硫減圧軽油 (DSVGO) をHPLCにより芳香環数に従って七つのフラクションに分割し, 極性成分を除く各フラクションをFI/MS測定して, その組成を明らかにした。VGOの多環芳香族チオフェン類の全濃度は21.6wt%以上と推定された。これは, 多環芳香族分の6割以上に相当する。DSVGOにはVGOに含まれない新たな芳香族化合物の分子量分布が認められ, これらはチオフェン類の脱硫による生成物と推測された。本反応条件下では, 主としてチオフェン類が芳香環数の少ない炭化水素に転化されるために ...
