Biomass and hydrocarb technology for removal at 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. A system has been devised which is unique in that it offers a method of actually decreasing the CO{sub 2} concentration in the atmosphere. The only economically and technically reasonable method for removal of CO{sub 2} from the atmosphere is by the photosynthesistic extraction of carbon from atmospheric CO{sub 2} and the formation of biomass, e.g., hemi-cellulose. The biomass is then thermochemically processed with fossil fuel gas, oil or coal to produce carbon black and methanol. The carbon is returned to the originating mine, for long term storage while the methanol is used as fuel. In this manner, methane gas and oil co-processed with biomass results in a net removal of CO{sub 2} from the atmosphere of about 46 lb CO{sub 2} per million Btu of methanol generated energy. Co-processing with coal results in no net CO{sub 2} generated or removed per unit of methanol energy generated. The process system is described and quantified in this paper. 1 fig. 1 tab.
