Abstract

Brazil is the largest producer of bioethanol, and sugarcane is the main raw material. Bioethanol is produced by both batch and continuous processes, and in some cases, flocculating yeast is used. This article analyzes the Brazilian Ethanol Program. For the 1996-1997 harvest, Brazil produced 14.16 billion L of ethanol and 13.8 million metric t of sugar, from 286 million metric t of sugarcane. These products were produced by 328 industries in activity, with 101 autonomous ethanol plants producing only ethanol, and 227 sugar mills producing sugar and ethanol. The sugar-ethanol market reaches about 7.5 billion US$/yr, accounting for direct and indirect revenues.

摘要

巴西是生物乙醇的最大生产国，甘蔗是主要原料。生物乙醇通过间歇式和连续式工艺生产，在某些情况下，会使用絮凝酵母。本文分析了巴西乙醇计划。在1996 - 1997收获季，巴西用2.86亿吨甘蔗生产了141.6亿升乙醇和1380万吨糖。这些产品由328家活跃的企业生产，其中101家独立乙醇厂仅生产乙醇，227家糖厂生产糖和乙醇。糖 - 乙醇市场每年的收入约为75亿美元，包括直接和间接收入。
