Abstract: To analyze the energy economic feasibility of biomass to bio-oil,a model for cost and benefit is established and the relevant indicators for the evaluation system are confirmed.The economic benefits of oil production by four kinds of raw biomass materials respectively are analyzed theoretically.By considering the influencing factors such as subsidies and raw material supplying radii,the relevant recommendations are proposed.Results show that the raw material cost accounts for a large proportion in total cost,as high as 60%-70%,followed by labor cost and depreciation cost.If rice husks,rice stalks and wheat stalks are used for raw materials,positive returns can be achieved even if subsidies are eliminated,and the investment can be recovered in about 7 years.For using corn stalks as raw material,at least RMB160 per ton subsidy for bio-oil is needed to achieve positive returns,and the investment can be recovered in around 14 years.
