HYDROPROCESSING PROCESS USING INCREASING CATALYST VOLUME ALONG SUCCESSIVE CATALYST BEDS IN LIQUID -FULL REACTORS

摘要

The present invention provides a process for hydroprocessing hydrocarbons comprising two or more catalyst beds disposed in sequence and wherein the catalyst volume increases in each subsequent catalyst bed. The process operates as a liquid-full process, wherein all of the hydrogen dissolves in the liquid phase. Hydrocarbons can be converted in the process to provide a liquid product including clean fuels with multiple desired properties such as low density and high cetane number.
