SYSTEMS AND PROCESSES FOR CATALYTIC PYROLYSIS OF BIOMASS AND HYDROCARBONACEOUS MATERIALS FOR PRODUCTION OF AROMATICS WITH OPTIONAL OLEFIN RECYCLE AND CATALYSTS HAVING SELECTED PARTICLE SIZE FOR CATALYTIC PYROLYSIS
SYSTEMS AND PROCESSES FOR CATALYTIC PYROLYSIS OF BIOMASS AND HYDROCARBONACEOUS MATERIALS FOR PRODUCTION OF AROMATICS WITH OPTIONAL OLEFIN RECYCLE AND CATALYSTS HAVING SELECTED PARTICLE SIZE FOR CATALYTIC PYROLYSIS
The present invention relates to compositions and methods for fluid hydrocarbon products, and more particularly to compositions and methods for fluid hydrocarbon products through catalytic cracking. Some embodiments relate to methods of producing certain aromatic products (e.g., benzene, toluene, naphthalene, xylene, etc.) through catalytic cracking. Some such methods may include the use of a composition comprising a mixture of a solid hydrocarbonaceous material and a non-uniform pyrolysis catalyst component. In some embodiments, the olefin compound may be co-fed to the reactor and / or separated from the product stream and recycled to the reactor to improve the yield and / or selectivity of the particular product. The process described herein may also comprise a special catalyst. For example, in some cases, a zeolite catalyst may be used. In some instances, the catalyst is characterized by a specific identified range of particle sizes that can improve the yield and / or selectivity of a particular product.
