TSS Consultants For the City of Gridley, California Gridley, California



This report is in response to Task 3 of the National Renewable Energy Laboratory (NREL) Subcontract No. ZCO-2-32065-01, that describes the Pearson Technologies Pilot Plant Gasifier and Syngas Conversion Testing for converting California rice straw into syngas and then the syngas into ethanol. The report on this task of the NREL Subcontract is part of an overall evaluation of using a modified Pearson Pilot Plant for processing rice straw into syngas and ethanol and the application of the Pearson technology for building a Demonstration Plant at Gridley. The Demonstration Plant would be located in the recently developed City of Gridley Industrial Park in Gridley, California (“Gridley”). This report also includes information on the feedstock preparation, feedstock handling, feedstock performance, catalyst performance, ethanol yields and potential problems identified from the pilot scale experiments.
