Abstract
Official abstract text for this publication.
This invention relates to a catalyst and method for hydrodesulfurizing naphtha. More particularly, a Co/Mo metal hydrogenation component is loaded on a high temperature alumina support in the presence of a dispersion aid to produce a catalyst that is then used for hydrodesulfurizing naphtha. The high temperature alumina support has a defined surface area that minimizes olefin saturation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for the hydrodesulfurization (HDS) of a naphtha having an olefin content of at least about 5 wt. %, based on the weight of the naphtha comprising: contacting the naphtha with a sulfided HDS catalyst under hydrodesulfurization conditions, wherein the catalyst is prepared by: (i) heating an alumina precursor to a temperature above at least about 800° C. to form a high temperature alumina, impregnating the high temperature alumina with an aqueo…
