Biomass and hydrocarb technology for removal of atmospheric CO sub 2
All mitigation scenarios proposed to date either tend to slow down the rate of atmospheric CO{sub 2} emissions or level out the CO{sub 2} concentration in the atmosphere. A unique system has been devised which offers a method of actually reducing the CO{sub 2} concentration in the atmosphere while still generating energy from fossil fuel. The only economically and technically reasonable method for removal of CO{sub 2} from the atmosphere is by the process of solar photosynthesis which extracts carbon from atmospheric CO{sub 2} by formation of biomass, e.g., hemi-cellulose. The biomass is then thermochemically converted by the HYDROCARB technology with fossil fuel, gas, oil or coal to produce carbon black and methanol. The carbon is returned to the earth, for long-term storage, while the methanol is used as fuel. There is also an energy enhancement in utilizing gas and oil for producing methanol compared to conventional methanol processes using these fuels. Co-processing with coal results in no net CO{sub 2} generated or removed per unit of methanol energy generated; however, a 2% increase in coal utilization is realized compared to conventional steam refining and methanol production. The process chemistry system is described and quantified in this paper. 11 refs.
