Development of hydrocracking process with light catalytic gasoil feedstock. [USSR]
Naphthas obtained by hydrocracking are usually low in octane number, requiring some sort of subsequent processing to upgrade them for use as commercial high-octane automotive gasolines. In some cases, by the use of specially developed catalysts and feedstocks with high contents of aromatic structures, automotive gasolines with satisfactory octane numbers can be produced directly by hydrocracking. In the reported experiments, the authors carried out experiments to develop a moderate-pressure process for hydrocracking light catalytic gasoil from a type 43-102 cat cracker operating in vacuum gasoil from West Siberian crudes. Since catalytic gasoils typically have high contents of organic sulfur and nitrogen compounds, unsaturates, and resins, the feedstocks used in this work was first hydrotreated. In this stage, alumina-cobalt-molybdenum catalyst from commercial production were used; in the hydrocracking stage, the researchers used a nickel-molybdenum zeolitic catalyst that had been tested in hydrocracking heavy naphtha under commercial conditions. Experimental data are tabulated and discussed. The results obtained have demonstrated the feasibility of hydrocracking light catalytic gasoils under a relatively low pressure (down to MPa) to obtain commercial high-octane automotive gasolines or feedstocks for catalytic reforming. 5 refs.
