Cobalt Technologies demonstrates its pretreatment process for making biobutanol  

By Gerald Ondrey |

Cobalt Technologies Mountain View, Calif.; www.cobalttech.com), announced the achievement of major progress toward commercial scale production of n-butanol by successfully demonstrating its biomass pretreatment process. Cobalt, in cooperation with Andritz Group (Graz, Austria; www.andritz.com), tested its dilute acid hydrolysis pretreatment process, the first step of Cobalt’s process for converting sugars into n-butanol for use as a renewable chemical or fuel. “Demonstrating our high-yield pretreatment process is a key milestone for Cobalt as we prove that our n-butanol technology will efficiently work at commercial scale and at an attractive low cost,” says Bob Mayer, CEO of Cobalt Technologies. “This is a very exciting time at Cobalt as we continue our path to commercialization and deepen our relationships with key partners.” Cobalt conducted the testing in the Andritz pulp-and-paper mill demonstration facility in Springfield, Ohio, which is specifically designed to validate new processes before commercial-scale implementation. Cobalt’s dilute acid-hydrolysis pretreatment process, which extracts sugars from ligno-cellulosic biomass, was validated on woody biomass, bagasse and agricultural…
