Deep Deoxygenation of Biocrudes Utilizing Fluidized Catalytic Cracking Co-Processing with Hydrocarbon Feedstocks
A system and method produce hydrocarbons from biomass by fluid catalytic cracking. In one embodiment, the system is a fluid catalytic cracking system. The system includes a riser. The riser contains a catalyst. The system also includes a biological feed comprising biomass-derived liquid for the riser. In addition, the system includes a hydrocarbon feed comprising hydrocarbons for the riser. The biological feed and the hydrocarbons react in the riser in the presence of the catalyst to convert at least a portion of the biological feed and the hydrocarbons to hydrocarbon products. The hydrocarbon products comprise a concentration of oxygen from about 0.005 wt. % to about 6 wt. %.
Catalysts useful for biomass pyrolysis and bio-oil upgrading
Catalysts useful in transforming biomass to bio-oil are disclosed, as are methods for making such catalysts, and methods of transforming biomass to bio-oil. The catalysts are especially useful for, but are not limited to, microwave- and induction-heating based pyrolysis of biomass, solid waste, and other carbon containing materials into bio-oil. The catalysts can also be used for upgrading the bio-oil to enhance fuel quality.
Production of lubricant base oils from biomass
Systems and methods are provided for processing a feed derived from a biomass source that contains nitrogen in the form of fatty amides, e.g., derived from hydrothermal processing of a biomass source feed, while reducing/minimizing the amount of heteroatom removal performed during subsequent/concurrent hydroprocessing. Optionally, the feed can also contain free fatty acids. This is accomplished in part by first exposing the feed to a catalyst comprising a rare earth oxide, alkali oxide, and/or alkaline earth oxide, which can remove the nitrogen heteroatoms from the compounds within the feed or can convert the nitrogen to a form readily removed in subsequent hydroprocessing. The catalyst may also suitable for catalyzing coupling (such as condensation) or conversion reactions of amides, carboxylic acids, carboxylic acid derivatives, and/or other molecules in the feed suitable for participating in the coupling reaction.
Process for converting a biomass material
A process for converting a biomass material comprising a) converting a biomass material in one or more steps into one or more C3-C12 oxygenates; b) contacting the one or more C3-C12 oxygenates with hydrogen at a hydrogen partial pressure of more than 1.0 MegaPascal in the presence of a sulphided carbon-carbon coupling catalyst; wherein the carbon-carbon coupling catalyst comprises equal to or more than 60 wt % of a zeolite and in the range from equal to or more than 0.1% wt to equal to or less than 10 wt % of a hydrogenation metal, based on the total weight of the carbon-carbon coupling catalyst.
Process for converting one or more C3-C12 oxygenates
A process for converting one or more C3-C12 oxygenates comprising oxygenates comprising: contacting a feed, which feed comprises one or more C3-C12 oxygenates, with hydrogen at a hydrogen partial pressure of more than 1.0 Mega Pascal in the presence of a sulphided carbon-carbon coupling catalyst; wherein the carbon-carbon coupling catalyst comprises equal to or more than 60 wt % of a zeolite and in the range from equal to or more than 0.1 wt % to equal to or less than 10 wt % of a hydrogenation metal, based on the total weight of the carbon-carbon coupling catalyst; and wherein the zeolite comprises 10-membered and/or 12-membered ring channels and a Silica to Alumina molar Ratio (SAR) in the range from equal to or more than 10 to equal to or less than 300.
Catalytic fast pyrolysis process
The present invention provides an improved catalytic fast pyrolysis process for increased yield of useful and desirable products, while greatly reducing or eliminating fouling of various critical process lines which are likely to transfer heavy hydrocarbons, aromatics and oxygenates. The process comprises steps including feeding a fluid solvent stream having a Snyder Polarity Index of at least 2.4 to one or more of i) the raw fluid product stream from a catalytic fast pyrolysis process fluidized bed reactor to a first separation system, ii) the fluid product stream from the first separation system to a quench vapor/liquid separation system, iii) the vapor phase stream from the quench vapor/liquid separation system to a product recovery system, and, optionally, to the spent catalyst steam stripping system upstream of the catalyst regeneration system.
Renewable high density turbine and diesel fuels from sesquiterpenes
A fuel and method for conversion of sesquiterpenes to high density fuels. The sesquiterpenes can be either extracted from plants or specifically produced by bioengineered organisms from waste biomass. This approach allows for the synthesis of high performance renewable fuels.
COMBINED OLEFIN AND OXYGENATE CONVERSION FOR AROMATICS PRODUCTION
Systems and methods are provided for inclusion of olefins in the reaction environment for an oxygenate conversion process. For conversion processes involving a metal-promoted zeolitic catalyst, addition of olefins to an oxygenate feed can reduce or minimize loss of aromatic selectivity as the catalyst is exposed to the feed. Additionally or alternately, for conversion processes involving a zeolitic catalyst including a zeolite other than an MFI framework type zeolite, addition of olefins to an oxygenate feed can reduce or minimize loss of activity for oxygenate conversion as the catalyst is exposed to the feed.
Method for preparing high-quality lubricant from biomass-derived fatty acid
Disclosed is a method for producing a quality lubricant base oil (meeting the standard of Group III or higher) comprising: decarbonylating mixed fatty acids derived from oils and fats of biological origin to produce mixed olefins; oligomerizing the mixed olefins to produce an olefinic lubricant base oil; and performing hydrogenation to remove olefins from the olefinic lubricant base oil.
