摘要： A method of increasing the selective desulfurization of naphtha feed streams that includes: combining a naphtha feed stream with a hydrogen containing gas to form a combined feed stream and reacting the combined feed stream over a monolithic honeycomb catalyst bed containing hydrodesulfurization catalyst components to give a desulfurized naphtha. In conducting such an illustrative embodiment, the percent desulfurization of the naphtha is preferably greater than about 50% and the percent olefin hydrogenation of the naphtha is preferably less than about 50%. The monolithic honeycomb catalyst bed of one alternative and illustrative embodiment preferably has a channel density of about 25 to 1600 cells per square inch; a channel size from about 0.1 to 10 mm; and a channel wall thickness of about 0.01 to about 2.0 mm. The illustrative method should be carried out such that the octane number (R+M/2) of the naphtha feed stream is reduced by no more than 3.0 at 95% desulfurization and preferably no more than 1.5. The hydrodesulfurization catalyst components include a powdered refractory oxide and transition metal catalyst compounds. Alternatively the hydrodesulfurization catalyst components may be impregnated into the monolithic honeycomb catalyst bed itself. Preferable hydrodesulfurization catalyst components include a Group VIII metal containing compound and a Group VIB metal containing compound. Alternatively the hydrodesulfurization catalyst components may further include a phosphorous promoter.

摘要： Substantially non-microcracked, porous, cordierite ceramic honeycomb bodies are provided. Although exhibiting moderately high thermal expansion (CTE) between 7×10−7 to 16×10−7/° C. (25-800° C.), the honeycomb bodies exhibit relatively high thermal shock parameter (TSP), such as TSR≧525° C. by virtue of a high MOR/E ratio, and/or low Eratio=ERT/E1000° C. and well interconnected porosity, as witnessed by a relatively high pore connectivity factor (PCF). A method of manufacturing the honeycomb ceramic structure is also provided.
