The life cycle assessment of automotive biological butanol

KEYWORD: Biological Butanol; Life Cycle Assessment; Energy Consumption; Emission; Economy ABSTRACT: A life cycle energy, emission and economic assessment model of biological butanolgasoline blend fuel was established based on life cycle. Then, the life cycle energy, environment, and economy of biological butanol-gasoline blend fuel used as automotive fuel were assessed. Comparing with conventional gasoline, biological butanol-gasoline blend fuel has higher life-cycle total energy, and fossil fuels consumption, higher HC, NOX, SOX, PM, and CO2 pollutants, higher life cycle cost, lower petroleum consumption, lower CO, and CH4 pollutants. The promotion and application of biological butanol is beneficial for vehicles to reduce the consumption of oil, but needs subsidy.
