Hydrodesulfurization, deoxygenation and dewaxing processes with water stable catalysts for biomass-containing hydrocarbon feedstocks

摘要

This invention relates to a method for hydroprocessing feedstreams containing both sulfur-containing mineral oils and biomass-derived feedstocks in a single reactor configuration. The process produces a desulfurized, deoxygenated and dewaxed hydrocarbon product having reduced oxygen content, increased iso-paraffin content, low n-paraffin content, and good cold flow properties. In preferred embodiments, the processes herein utilize water tolerant hydrodewaxing catalysts in order to prevent deactivation and/or catalyst loss due to water produced during the deoxygenation reactions in the biomass components.
