Corporate Overview

Advanced technologies for the conversion of biomass to bio-fuels, bio-chemicals and renewable power

Formed in 1996Proprietary steam reforming gasification system developed with over $50 million of R&D investment from private investor, the U.S. Department of Energy, the California Energy Commission, and the pulp and paper industryResearch facilities in RDU and UtahProven technology currently in commercial operationCommercializing the Integrated Biorefinery Platform

Thermochemical Platform Facts

The Thermochemical platform biorerfinery includes:Biomass preparationBiomass to syngas processGas clean upCatalytic gas to liquids process, and/orCombined cycle energy plantEnergy recovery

The Thermochemical platform is exothermicThe Thermochemical platform thermally integrates with an endothermic host process for superior economics.

Gas Clean Up

GCU sized for 10% slipstream and includes the following:Primary Gas Clean Up

HRSG to cool syngas to ~ 500ºFVenturi scrubber for removal of particulateGas Cooler for condensation of residual steamProprietary solvent extraction of tarsScrubber for removal of any trace H2S

Secondary Gas Clean UpCompressor (25 psig to 440 psig)Scrubbers to remove HCN and NH3Packed guard beds to eliminate H2S and COSParticulate filters
