The life cycle assessment of automotive biological butanol

摘要

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, NO_X, SO_X, PM, and CO_2 pollutants, higher life cycle cost, lower petroleum consumption, lower CO, and CH_4 pollutants. The promotion and application of biological butanol is beneficial for vehicles to reduce the consumption of oil, but needs subsidy.
