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

摘要

A process for separating and purifying a product from the catalytic rapid pyrolysis of biomass is described. In a preferred method, a portion of the product from the pyrolysis reactor is recovered and purified using a hydrotreating step to reduce the content of sulfur, nitrogen and oxygen components and to hydrogenate the olefin to produce an aromatic product that meets commercial quality specifications .
