摘要： Removing impurities from a heptane stream by contacting the heptane stream with an acidic catalyst, wherein the contacting reduces a concentration of one or more close boiling impurities, one or more olefins, or both. The impurities are isomerized via contact with the acidic catalyst into species that possess lower octane levels or that do not possess boiling points as near to the boiling point of n-heptane, which promotes separation of the impurities via distillation. Close boiling impurities may include such compounds as cis-1,2-dimethylcyclopentane and methylcyclohexane or may be compounds having boiling points at a standard pressure of 760 Torr in the range of about 96.5 to about 100.5 degrees Celsius including such compounds as cis-1,2-dimethylcyclopentane and methylcyclohexane. The concentration of cis-1,2-dimethylcyclopentane and methylcyclohexane may be reduced by at least about 25 and 10 percent by weight, respectively. The concentration of olefins, as measured by the Bromine Index, may be reduced by at least about 25 percent by weight.

摘要： A computer implemented method for modeling and simulating a hydrotreating reactor is disclosed where a first step in the simulation utilizes a computer data base of reaction kinetic parameters for hydrotreating sulfur and metals contaminated residuum and gas oil fractions. The data base is extended to include parameters and physical properties for residuum and gas oil fractions that are obtained from several different source locations. A group of equations, which are functions of catalyst properties, reactor parameters and feedstock composition, models the reaction by predicting yields, hydrogen consumption, contaminant levels, and physical properties of the reactor product. The simulation adjusts the kinetic parameters for reaction conditions to be simulated, such as temperature, catalyst activity, hours on stream, space velocity etc., and solves the model equations for the desired results. The simulation is particularly useful for evaluating a slate of crude oils to aid in selecting an economical crude oil for future processing in a refinery.
