The technology of the fermentation of biomass producer gas to ethanol is discussed in this article.

文章简要讨论了生物质合成气发酵生产乙醇的技术途径。

"We are not interested in becoming the Saudi Arabia of ethanol," said Eduardo Carvalho, director of the National Sugarcane Agro-Industry Union, a producer's group. It's not our strategy because it doesn't produce results.

"我们对成为乙醇领域中的沙特阿拉伯不感兴趣，"全国甘蔗农工联合会的主席埃得瓦多·卡瓦略说，那并非我们的战略，因为那不会有成效的。

From thermal analysis, weight loss occurs pronouncedly at temperatures above 300 oC in air and the residual weight increases with the reaction temperature. The particle size decreases with the increasing ethanol concentration., while the BET surface area decreases when the concentration of water is increased. Pore size measured from the as-synthesized particles is about 2.7 - 4 nm and this becomes slightly smaller after calcination which is about 3 - 5 nm.

TG/DTA中温度上升至约300 oC时，重量开始明显失重，随著合成反应温度上升，最终残留量由1~3%提高为约5~7%，动态光散射粒径分析发现随著乙醇含量增加，煅烧前与煅烧后的粒径尺寸均有下降趋势，随著水含量的增加，比表面积值随著下降，煅烧后的壳层孔隙尺寸约为3~5nm，煅烧前的壳层孔隙尺寸为2.7~4 nm，煅烧后的孔隙度会略为上升。

The linear relationship to detect methanol was not effected by a few amount of ethanol, acetone and propanol etc.

乙醇、丙酮和丙醇等干扰物不影响测定的线性关系，特别对水的交叉敏感相当低，可以在真实的大气条件下测定甲醇的含量。

PEG-20000 is used as solid phase of capillary column, and propyl alcohol is selected for the standard material, and the ethanol content is determined by the inner standard method.

用PEG-20000作固定相的毛细管色谱柱，正丙醇为内标物，用内标法测定消毒片中的乙醇含量。

The invention solves the problems that the prior acetone air sensitive material can not response to acetone gas selectively due to the existence of ethanol and normal propyl alcohol, and has high minimal detection limit to the acetone.

它解决了现有丙酮气敏材料由于乙醇、正丙醇的存在无法对丙酮气体进行选择性响应，及对丙酮的最低检测限较高的问题。

The resonant peak shifted towards longer wavelength with the increasing volume fraction of methanol,ethanol,propyl alcohol,acetone and formaldehyde with high sensitivities and linear relations.

结果表明，谐振波长随甲醇、乙醇、丙醇等醇类化合物，以及丙酮、甲醛等蒸气体积分数的上升而向长波方向移动，具有高的灵敏度，且两者基本呈线性关系。
