Publication number: 20140283439Abstract: A process for optimizing a biomass feedstock for gasification for the production of syngas. The biomass feed, which is preferably a lignocellulosic material, is subjected to controlled torrefaction so that the biomass only undergoes a weight loss of about 10% to 15% on a dry ash free basis. This increases the energy density and friability of the so treated biomass and results in higher efficiency on subsequent gasification.Type: ApplicationFiled: March 21, 2013Publication date: September 25, 2014Applicant: SynGas Technology, LLCInventors: Jacqueline R Hitchingham, Lloyd R.
