摘要:
A process is disclosed for fluid catalytic cracking of oxygenated hydrocarbon compounds such as glycerol and bio-oil.In the process the oxygenated hydrocarbon compounds are contacted with a fluid cracking catalyst material for a period of less than 3 seconds.In a preferred process a crude-oil derived material, such as VGO, is also contacted with the catalyst.
摘要:
A catalytic process for converting biomass-derived carbohydrates to liquid alkanes, alkenes, and/or ethers is described. The process uses combinations of self- and crossed-aldol condensation reactions, dehydration reactions, and hydrogenation reactions, over specified metal-containing catalysts, to yield alkane, alkene, and ether products from carbohydrate reactants.
摘要:
A method is disclosed for producing a mixture of CO and H2 (syn-gas). The method comprises contacting particles containing a coke deposit with oxygenated molecules derived from biomass. In a preferred embodiment the particles are catalyst particles.The method may be carried out in the regenerator of a conventional fluid catalyst cracking (FCC) unit.

摘要:
This invention relates to compositions and methods for fluid hydrocarbon product, and more specifically, to compositions and methods for fluid hydrocarbon product via catalytic pyrolysis. Some embodiments relate to methods for the production of specific aromatic products (e.g., benzene, toluene, naphthalene, xylene, etc.) via catalytic pyrolysis. Some such methods may involve the use of a composition comprising a mixture of a solid hydrocarbonaceous material and a heterogeneous pyrolytic catalyst component. In some embodiments, an olefin compound may be co-fed to the reactor and/or separated from a product stream and recycled to the reactor to improve yield and/or selectivity of certain products. The methods described herein may also involve the use of specialized catalysts. For example, in some cases, zeolite catalysts may be used. In some instances, the catalysts are characterized by particle sizes in certain identified ranges that can lead to improve yield and/or selectivity of certain products.
