摘要：

Hydrocracking reaction of ultraheavy oils is very complicated one and the reaction performance is affected not only by reaction conditions but also by feedstock properties. In order to estimate reaction performance of a bench scale experimental unit (BSU, 3bbl/day) accurately, we proposed a kinetic model for the hydrocracking reaction and found that the following parameters strongly affect to the reaction performance; i.e. temperature, pressure, catalyst loading, actual residence time, BTM (+525 °C), nitrogen, sulfur and the Conradson Carbon Residue (CCR) value in feedstocks and H/C in recycled BTM solution. Using these parameters, the rate constants were obtained by fitting experimental data of the BSU and each yield was estimated based on CSTR model with relatively small errors. The estimation method would be a basis to develop a simulation program for scaleup engineering. © 2023 Japan Institute of Energy. All rights reserved.
