Abstract: Disclosed are processes for improving the performance of a computer system operating a software program for calculating operating parameters and results of hydrocarbon processing units by providing a method of estimating and consolidating molecular composition components and properties of hydrocarbon mixtures such as petroleum fractions. The method provides a reduced number of representative compounds that closely match the characteristics of the complete molecular composition of the mixture that may be used to increase efficiency of a computer system, improve the operation of refinery process and that may be disposed on non-transitory machine-readable media.

Abstract: A method is provided for making a catalyst support, and includes the steps of providing an aqueous suspension of refractory inorganic oxide and refractory inorganic carbide; forming the suspension into droplets; exposing the droplets to a gelling agent whereby the droplets are at least partially solidified so as to provide substantially sphere-shaped portions of refractory inorganic oxide and refractory inorganic carbide; and drying and calcining the sphere-shaped portions so as to provide substantially spherical particles of catalyst support containing refractory inorganic oxide and refractory inorganic carbide. Catalytically active metal phases and hydrogenation processes using the catalyst are also described.
