Title: A feasibility study for the coprocessing of fossil fuels with biomass by the Hydrocarb Process

Abstract

A feasibility study was undertaken at Brookhaven National Laboratory to determine the potential of coprocessing biomass with fossil fuel to produce a clean carbon fuel and coproduct methanol by the Hydrocarb Process. The Hydrocarb Process consists of three basic process steps: (1) the hydropyrolysis of a carbonaceous feedstock to a methane-rich process gas stream followed by (2) the thermal decomposition of methane to carbon and hydrogen part of which is recycled and (3) the third is the conversion of CO with hydrogen to methanol. Any carbonaceous material can be used as feedstock. The coproducts are clean particulate carbon black, liquid methanol and gaseous hydrogen or methane. Background process chemistry data are presented for the hydropyrolysis of carbonaceous material and the pyrolysis of methane. A preliminary process design and evaluation of a Hydrocarb coprocess system is presented. A computer simulation model of the process developed by the Hydrocarb Corporation is used to determine mass and energy balances for alternate process cycles. For purposes of mitigating the potential CO{sub 2} greenhouse effect, coprocessing fossil fuel with biomass allows the option of sequestering the carbon and utilizing only the hydrogen-rich coproduct methanol as fuel which reduces CO{sub 2} emissions significantly. In this mannermore » not only is the CO{sub 2} emission reduced but CO{sub 2} can be removed from the atmosphere and sequestered. Furthermore the conversion of fossil fuel (natural gas) to methanol is greatly enhanced compared to conventional conversion of fossil fuel to methanol. Preliminary economic analysis indicates potential economic competitiveness of the Hydrocarb coprocess compared to conventional methods of fossil fuel conversion such as steam-oxygen reforming of natural gas. It is concluded that the system appears technically and economically feasible. 28 refs., 12 figs., 13 tabs.« less
