Abstract

A new conceptual design for refining crude oil was proposed. The process combined a direct pretreatment process of crude oil by adsorption and a hydrotreating process of the pretreated crude oil. The pretreatment process was designed to remove mainly metals, asphaltene, and nitrogen compounds to enhance the hydrotreating reactivity of the pretreated crude oil. The adsorptive pretreatment of Kuwait Export Crude was performed over some potential adsorbents, including activated alumina and activated carbons. The activated carbons showed better adsorption performance for removing sulfur and nitrogen compounds from KEC. Among carbon adsorbents, ACSA15 gave the highest adsorption capacity, especially for removing nitrogen compounds, and hence, was selected for the adsorptive pretreatment process. The catalytic hydrotreatment of the original and pretreated crude oil was conducted over a commercial CoMo catalyst to examine the effect of the adsorptive pretreatment on the hydrotreatment. The adsorptive pretreatment process improved significantly the hydrotreating reactivity of crude oil. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
