甘蔗——车用乙醇产业首选的原料作物

本文对甘蔗与其他能源作物的发酵成分、经济产量、单位面积的车用乙醇产量、成本和效益等进行了深入全面的分析,结果指出:甘蔗的发酵成分更易转化成乙醇,经济产量比其他能源作物高3～8倍,单位面积的车用乙醇的产量是其他能源作物的3～7倍,生产等量车用乙醇需要的土地是其他能源作物的1/15～1/3,原料成本比其他能源作物都低,经济效益比其他能源作物都高,公顷经济效益是其他能源作物的4～40倍.所以,甘蔗是车用乙醇产业首选的原料作物.

Cane is the First-Choice Crop for Raw Material to Produce Automobile Alcohol

This paper analyzed the fermentable compositions, economic yield, automobile alcohol output per unit area, cost and effect etc. for cane with other energy crops. The fermentable compositions of canes can be easily transformed into alcohol, and the economic yield is 3-8 times of other energy crops, the automobile alcohol output per unit area is 3-7 times of other energy crops. The land use is one-fifteen to one third of other energy crops for equal quantity Automobile alcohol. The cost of material is 50% lower than other energy crops, the economic effect is 20%-90% higher than other energy crops for per tonnage automobile alcohol, economic effect per hectare is 10-175 times of other energy crops. According to this paper, cane is the first choice for materials to produce automobile alcohol.
