Abstract
This specification discloses a complete method to manufacture polyester articles from freshly harvested ligno-cellulosic biomass. The process steps include pretreating the biomass and the converting the lignin to one of several possible organic steams by deoxygenating and dehydrogenating the lignin in the presence of a Raney Nickel catalyst, separating the organics, and then processing the organics into polyester feedstocks and converting those feedstocks to polyester.
