Efficient new process uses CO2 in gasification

his new method of gasification could iincrease the efficiency and lower the cost of syngas prodtion from biomass. It makes direct uof CO2 -- a greenhouse gas. Syngas can then be made into many types of liquid fuels such as ethanol, or be upgraded for use as a natural gas substitute in cars, heating, generation of electricity, or other uses.
Columbia researchers explore new process to create greener fuels: "While a typical gasification process uses only steam to convert biomass into syngas, synthetic gas containing a mixture carbon monoxide and hydrogen, Castaldi’s new method replaces 30 percent of the water with carbon dioxide. Researchers believe that these findings carry exciting potential and hope the process will be able to improve the overall efficiency of fuel production when used on a large scale. Syngas can be converted into a variety of different chemicals and fuels, including diesel products."
