Abstract: A composition comprises a hydrodesulfurization or hydrodenitrogenation, or both, catalyst component and a support component which comprises aluminum, zirconium, and a borate. A process for making the composition comprises the steps of (1) contacting an aluminum salt, a zirconium salt, and an acidic boron compound under a condition sufficient to effect the production of a support component comprising aluminum, zirconium, and borate and (2) combining a hydrodesulfurization or hydrodenitrogenation, or both, catalyst component with the support component. Also disclosed are processes for removing organic sulfur compounds or organic nitrogen compounds, or both, from hydrocarbon-containing fluids which comprise contacting a hydrocarbon-containing fluid, with a hydrogen-containing fluid, in the presence of a catalyst composition.

Abstract: A catalyst composition and a process for hydrodealkylating C.sub.9 + aromatic compounds such as, for example, trimethylbenzenes, to C.sub.6 to C.sub.8 aromatic hydrocarbons such as toluene and xylenes are disclosed. The composition comprises an alumina and a silica wherein the weight ratio of aluminum to silicon is in the range of from about 0.005:1 to about 0.25:1. The process comprises contacting, in the presence of the catalyst composition, a fluid which comprises a C.sub.9 + aromatic compound with a hydrogen-containing fluid under a condition sufficient to effect the conversion of a C.sub.9 + aromatic compound to a C.sub.6 to C.sub.8 aromatic hydrocarbon; and the C.sub.9 + aromatic compound contains at least 9 carbon atoms.

Abstract: A catalyst composition and a process for converting a hydrocarbon stream such as, for example, a C.sub.9 + aromatic compound to C.sub.6 to C.sub.8 aromatic hydrocarbons such as xylenes are disclosed. The catalyst composition comprises an aluminosilicate, and a metal wherein the weight ratio of aluminum to silicon is in the range of from about 0.002:1 to about 0.6:1. The process comprises contacting a hydrocarbon stream with the catalyst composition under a condition sufficient to effect the conversion of a hydrocarbon to a C.sub.6 to C.sub.8 aromatic hydrocarbon.

Abstract: A composition and method of making a strength enhanced composition are described. The composition comprises zinc oxide, silica and colloidal oxide solution. The colloidal oxide solution is utilized as a binding agent to provide a strength enhanced absorbent composition that can be utilized in an absorption process for the purpose of removing sulfur contaminants from fluid streams.
