Catalytic pyrolysis of solid biomass and related biofuels, aromatic, and olefin compounds

摘要

This invention relates to compositions comprising fluid hydrocarbon products, and to methods for making fluid hydrocarbon products 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 involve the use of a composition comprising a mixture of a solid hydrocarbonaceous material and a heterogeneous pyrolytic catalyst component. The methods described herein may also involve the use of specialized catalysts. For example, in some cases, zeolite catalysts may be used.

主权项

1. A method for producing a fluid hydrocarbon product from a solid hydrocarbonaceous material, comprising:
providing a solid catalyst in a fluidized bed reactor; feeding the solid hydrocarbonaceous material to the fluidized bed reactor; pyrolyzing within the fluidized bed reactor at least a portion of the hydrocarbonaceous material under reaction conditions sufficient to produce a pyrolysis product; and catalytically reacting at least a portion of the pyrolysis product using the solid catalyst under reaction conditions sufficient to produce the fluid hydrocarbon product; the catalyst being a zeolite catalyst comprising silica and alumina, and further comprising a metal and/or metal oxide comprising nickel, platinum, vanadium, palladium, manganese, cobalt, zinc, copper, chromium, gallium, iron, or a mixture of two or more thereof; wherein the fluid hydrocarbon product comprises at least about 7.2 wt % of one or more aromatic compounds, the weight percent of aromatic compounds being calculated as the weight of the aromatic compounds present in the fluid hydrocarbon product divided by the weight of the hydrocarbonaceous material used to produce the pyrolysis product, the aromatic compounds comprising benzene, toluene and/or xylene.
