Energy content, biomass components

Table II contains a summary of energy requirements for 1975 corn production in the United States. The individual energy components in 1975 corn production are listed in Table A-1. This table shows that the three largest sources of energy consumption are fuel, fertilizer, and irrigation. Table A-2 contains the energy content of the corn grain and associated biomass material (stover and cobs). The energy production (810,000 Btu/bu corn) is about 6.6 times the energy used in producing the corn.

Gibbs free energy minimization provides a practical basis for investigating the fate and removal of alkali species and sour gas components from biomass gasification product gas as a function of temperature and composition of inlet streams. The methane content of the product gas - a result of non-equilibrium conversion - is accounted for in the procedure by setting as inert compounds the corresponding fractions of carbon and hydrogen in the biomass feedstock [42],...
