Comparison of the Performance of Upflow and Downflow Small-Reactors in Hydrodesulfurization Reactions

摘要

An experimental study for comparing the behavior of a small-reactor in the hydrodesulfurization of straight-run gas oil with two modes of operation, upflow and downflow, is presented. The reactor has 525 mm length and 14.3 mm internal diameter. Experiments were conducted at commercial HDS operating conditions (5.3 Mpa total pressure, 356.2 mL/mL hydrogen-to-oil ratio, reaction Temperature of 613-653 K, and LHSV of 1.0-2.5 h~-1).
