Development of Superior Denitrogenation and Isomerization Catalysts for Processing Crude Oil Derived from Shale. Part II.
Abstract
A number of facts have been observed during the course of the study and these have led to further tests or catalyst preparations, some of which have been completed, but many are in obeyance awaiting funding. The support is an extremely critical factor influencing the catalyst performance profoundly. Not only is the composition of the support critical but the method of preparation is equally critical. The hydrogenation characteristics of the catalyst are critical, and the ratio of Mo03 to hydrogenation metal also seems to be influenced by the support (possibly acidity or reactivity to form a solid-state reaction product between the composite support and the hydrogenation metal). The sulfiding of the catalyst prior to and during use is influenced by the support composition and hydrogenation metal. New presulfiding techniques probably will be required. HDN rates as high as three times that of a standard commercial catalyst (3.5% Ni, 18% Mo03, 78% gamma alumina) was achieved for alaphatic amines, but this was not followed by similar improvement in shale oil.
