Patent number: 8658025Abstract: Biomass is used as a co-feed for a heavy petroleum oil coking process to improve the operation of the coking process and to utilize biomaterial for the production of transportation fuels. The coking process may be a delayed coking process or a fluidized bed coking process and in each case, the presence of the biomass will decrease the coke drying time so reducing coke handling problems in the unit besides forming a superior coke product. In the case of a fluidized bed coking process using a gasifier for the coke, the addition of an alkali metal salt improves the operation of the gasifier.Type: GrantFiled: March 1, 2011Date of Patent: February 25, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: Michael Siskin, Glen E. Phillips, Simon R. Kelemen, Walter Weissman

Patent number: 8147676Abstract: The present invention relates to an improved delayed coking process. A coker feed, such as a vacuum resid, is treated with (i) a metal-containing agent and (ii) an oxidizing agent. The feed is treated with the oxidizing agent at an oxidizing temperature. The oxidized feed is then pre-heated to coking temperatures and conducted to a coking vessel for a coking time to allow volatiles to evolve and to produce a substantially free-flowing coke. A metals-containing composition is added to the feed at at least one of the following points in the process: prior to the heating of the feed to coking temperatures, during such heating, and/or after such heating.Type: GrantFiled: October 21, 2005Date of Patent: April 3, 2012Assignee: ExxonMobil Research and Engineering CompanyInventors: Michael Siskin, David T.

Patent number: 7344889Abstract: A method of predicting the composition of hydrocarbon products of a complex carbonaceous material when exposed to specific time and temperature conditions is disclosed. In one embodiment, the material is characterized to obtain elemental, chemical and structural parameters. A representative chemical structure of the material is constructed based on the characterization information. The representative chemical structure is then stochastically expanded to a molecular ensemble chemical structural model that includes heteroatoms. The chemical structural model is coupled to a compositional yield model and the composition of the material products is determined using kinetic modeling.Type: GrantFiled: April 30, 2003Date of Patent: March 18, 2008Assignee: Exxonmobil Upstream Research CompanyInventors: Simon R.
