Abstract:

As a big agricultural country, the yearly capacity of straw is about seven hundred million tons in our country. It is a very valuable study that low-cost agricultural waste straw as a raw material are covered into energy. It talks about in aspect of ethanol, methane-methanol production and gasification, liquefaction for diesel oil product based on feed stock of straw stalk. Using straw to create energy causes concern. It not only reduces costs, but also mitigates the problem that causes by straw. Compare with the principle, operational condition, equipment and economy so that find a most favorable developing orientation among straw stalk converting into energy sources. The final result shows that quantity of heat of fuel ethanol reaches to max (18900 MJ) per ton of straw stalk with obvious benefit and great potential of fibrin ethanol. The utilization rate and economic returns of converting straw to ethanol which is a good way of using energy straw are higher than others.
