Publication number: 20230287280Abstract: A process for hydroprocessing a renewable feedstock involves introducing the renewable feedstock and hydrogen in a downward flow into a top portion of a fixed-bed reactor and distributing the downward flow to a top surface of a first catalyst bed in a manner such that the top surface is uniformly wetted across the reactor cross section. The feedstock then flows downwardly through the first catalyst bed, where it is reacted under hydroprocessing conditions sufficient to cause a reaction selected from the group consisting of hydrogenation, hydrodeoxygenation, hydrodenitrogenation, hydrodesulphurization, hydrodemetallization, hydrocracking, hydroisomerization, and combinations thereof. A hydrocarbon liquid separated from the reaction effluent is recycled to the renewable feedstock in a ratio of 0.4:1 to 1.8:1, based on the volume of the renewable feedstock.Type: ApplicationFiled: August 20, 2021Publication date: September 14, 2023Inventors: Nicolaas VAN DIJK, Andries Hendrik JANSSEN, Gerald Max LAWRENCE, Roy Léon Bernard HENKET, Julien SIGAUD

Patent number: 9376638Abstract: A process for the hydroconversion of a hydrocarbon feedstock. The process includes contacting the hydrocarbon feedstock with a catalyst in a first hydrocracking section to obtain a first hydrocarbon effluent stream which is separated into a gaseous stream, a light liquid stream and a heavy liquid stream. These liquid streams are fractioned into a number of fractions of hydrocarbons including a fraction of hydrocarbons having a boiling point above 350° C. This fraction of hydrocarbons is contacted with a catalyst in a second hydrocracking section to obtain a second hydrocarbon effluent stream that is separated to obtain a gaseous stream, a light liquid stream and a heavy liquid stream. These liquid streams are fractioned into a number of fractions of hydrocarbons including a heavy fraction of hydrocarbons having a boiling point above 350° C. This fraction of hydrocarbons is split into a major stream and a minor stream with the major stream being recycled and the minor stream is recovered.Type: GrantFiled: May 25, 2012Date of Patent: June 28, 2016Assignee: Shell Oil CompanyInventor: Nicolaas Van Dijk
