Effect of Prehydrogenation on Hydroconversion of Maya Residuum, Part 1: Process Characterization

摘要

Maya 650 deg F residuum was mildy prehydrogented over a standard, commercially available, hydrodesulfurization catalyst. The product was then distilled to yield hydrogenated Maya 650 deg F residuum. This prehydrogenated residuum, and the untreated Maya 650 deg F residuum were separately hydroprocessed further at different process severities. The resulting products were then examined by elemental analyses to determine the effects of the prehydrogenation step on overall conversion and product quality. 38 refs., 4 figs., 6 tabs.
