PROCESSES FOR CONVERTING BIOMASS TO BTX WITH LOW SULFUR, NITROGEN AND OLEFIN CONTENT VIA A CATALYTIC FAST PYROLYSIS PROCESS

摘要

Methods of separating and purifying products from the catalytic fast pyrolysis of biomass are described. In a preferred method, a portion of the products from a pyrolysis reactor are recovered and purified using a hydrotreating step that reduces the content of sulfur, nitrogen, and oxygen components, and hydrogenates olefins to produce aromatic products that meet commercial quality specifications.

主权项

1. A method for producing aromatic chemicals from the product stream of a catalytic pyrolysis process, comprising:
quenching the product stream; separating a first liquid phase and a first vapor phase, recovering aromatics from the first vapor phase; and hydrotreating at least a portion of the aromatics.
