  • Patent number: 8658025
    Abstract: 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.

  • Patent number: 8500829
    Abstract: A pyrolysis oil derived from a lignocellulosic biomass material is converted into precursors for liquid hydrocarbon transportation fuels by contacting the oil with water and carbon monoxide at elevated temperature, typically from 280 to 350° C., an elevated pressure, typically a total system pressure of 12 to 30 MPa and a CO partial pressure from 5 to 10 MPa and a weight ratio of water:biomass oil from 0.5:1 to 5.0:1, to dissolve the oil into the reaction mixture and depolymerize, deoxygenate and hydrogenate the oil, so converting it into liquid transportation fuel precursors.

  • Patent number: 8147676
    Abstract: 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.

  • Patent number: 8101066
    Abstract: An improved fluidized coking process wherein an effective amount of a basic material, preferably an alkali or alkaline-earth metal-containing compound, is added to the coking zone to mitigate agglomeration of the coke during the coking of a heavy hydrocarbonaceous feedstock to produce lower boiling products.

  • Patent number: 7344889
    Abstract: 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.
