小桐子种子产沼气潜力及其能源转换效率的研究

The Study on Biogas Production Potential and Energy Conversion Efficiency of Jatropha Curcas

以小桐子种子为原料进行沼气发酵,结果表明,小桐子种子在常温条件下发酵产沼气的潜力为895mL/gTS,明显优于其他常见农村沼气发酵原料,小桐子种子沼气发酵的能源转换效率可达76.84%;其TS产气率分别是猪粪发酵的3.6倍、牛粪的5倍、玉米秸秆的3倍。

When using Jatropha curcas as biogas fermentation material,we can get the result that the biogas production potential of J.curcas is 895mL/gTS under the condition of room temperature,which is superior to other raw material,and the energy conversion efficiency J.curcas is 76.84%.The TS gas production rate of J.curcas is a multiple of 3.6 to pig manure,a multiple of 5 to cow dung,and a multiple of 3 to corn stalk.
