Publication number: 20230109160Abstract: Systems and methods are provided for integrated pyrolysis and gasification of a biomass feed, either as a separate feed or under co-processing conditions. The integrated pyrolysis and gasification can be performed using any convenient reactor configuration, such as fluidized coking reactor configuration or a fluid catalytic cracking reactor configuration. The biomass feed can initially by pyrolyzed to form liquid products, gas phase products, and char. The char can then be used as the input feed to gasification. In aspects where the biomass feed is co-processed, the biomass can be co-processed with a co-feed that is suitable for processing under fluidized coking conditions or other pyrolysis conditions, such as a conventional fluidized coking feedstock.Type: ApplicationFiled: September 13, 2022Publication date: April 6, 2023Inventors: James R.

Patent number: 10414701Abstract: Systems and methods are provided for forming alkylate from an isoparaffin-containing feed. Olefins for the alkylation reaction can be generated from a portion of the isoparaffin-containing feed. This can be achieved, for example, by using selective oxidation to convert a portion of isoparaffins into alcohol, such as conversion of isobutane to t-butyl alcohol. The alcohol can then be converted to an alkene, such as conversion of t-butyl alcohol to isobutene, in the alkylation reaction environment in the presence of a solid acid catalyst. The solid acid catalyst can then facilitate alkylation of isoparaffin using the in-situ formed alkenes. A catalyst having an MWW framework is an example of a suitable solid acid catalyst.Type: GrantFiled: December 13, 2017Date of Patent: September 17, 2019Assignee: ExxonMoble Research and Engineering CompanyInventors: Jihad M.

Patent number: 9034595Abstract: Systems and methods are provided for enhancing the integration of processes for recovering products from algae-derived biomass. The enhanced process integration allows for increased use of input streams and other reagents that are derived from renewable sources. This increases the overall renewable character of the products extracted from the algae-derived biomass. The process integration can include exchange of input streams or energy between an algae processing system and a system for processing non-algal biomass. One example of improving process integration is using oxygenates that are generated in a renewable manner as a reagent for enhancing the algae processing system.Type: GrantFiled: December 14, 2011Date of Patent: May 19, 2015Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Paul D.
