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 in a one step process by combining the lignin with water, hydrogen, and an elemental metal catalyst such as Raney Nickel at the specificied temperature and pressures to produce very specific products, separating the organics, and then processing the organics into polyester feedstocks and converting those feedstocks to polyester. |
