Method for evaluating biomass-based ethyl levulinate

The invention belongs to the field of energy-oriented utilization of forestry wastes, and relates to a method for evaluating the environmental influence and energy consumption condition caused by analyzing utilization of biomass-based ethyl levulinate as liquid fuel subjectively, quantitatively and comprehensively. The method comprises the steps of: evaluating the environmental influence and energy consumption in the whole process from production of raw materials of ethyl levulinate to utilization of ethyl levulinate according to the life cycle theory of the biomass-based ethyl levulinate. The evaluation method can be used for evaluating and comparing the environmental influence and energy consumption in different stages of the life cycle of the biomass-based ethyl levulinate, and for evaluating and comparing the life cycle, environmental influence and energy consumption of biomass-based ethyl levulinate manufacturing plants of different scales.
