  • Process for the Sequential Hydroconversion and Hydrodesulfurization of Whole Crude Oil
    Publication number: 20100025293
    Abstract: The invention relates to a method for removing sulfur from crude oils using a catalytic hydrotreating process operating at moderate temperature and pressure and reduced hydrogen consumption. The process produces sweet crude oil having a sulfur content of between about 0.1 and 1.0 wt % in addition to reduced crude density. The method employs least two reactors in series, wherein the first reactor includes a hydroconversion catalyst and the second reactor includes a desulfurization catalyst.

  • PROCESS FOR CATALYTIC HYDROTREATING OF SOUR CRUDE OILS
    Publication number: 20090139902
    Abstract: A continuous process for upgrading sour crude oil by treating the sour crude oil in a two step process that includes a hydro-demetallization section and a hydro-desulfurization section, both of which are constructed in a permutable fashion so as to optimize the operating conditions and catalyst lifespan to produce a high value crude oil having low sulfur and low organometallic impurities.
