一、发达国家生物质能源标准化现状1.国外典型生物乙醇标准自1931年,巴西提出推广乙醇燃料的首部法规及首部乙醇燃料生产技术标准以来,一些国家先后颁布了生物燃料乙醇产品标准。燃料乙醇的主要指标有乙醇含量、甲醇含量、蒸发残余物、水含量、改性剂含量、无机氯化物、碳氢化合物、硫、磷、铜、铅、电导率、酸度、PH 值、相对密度、外观等,国外已制定生物质燃料乙醇标准的国家有巴西、美国、瑞典、波兰、日本、澳大利亚、印度、泰国等。美国是全球最大的燃料乙醇生产与消费国。20世纪30年代乙醇汽油在加州首次面世,70年代因为 I. Status Quo of Biomass Energy Standardization in Developed Countries 1. Typical Bio-ethanol Standards in Foreign Countries Since 1931, Brazil has promulgated the first ethanol-fuel legislation and the first technical standard for ethanol fuel production. Some countries have successively promulgated the biofuel ethanol product standards. The main indicators of fuel ethanol alcohol content, methanol content, evaporation residue, water content, modifier content, inorganic chloride, hydrocarbons, sulfur, phosphorus, copper, lead, conductivity, acidity, PH value, relative density , Appearance, etc., foreign countries have developed bio-fuel ethanol standards in Brazil, the United States, Sweden, Poland, Japan, Australia, India, Thailand and so on. The United States is the world’s largest producer and consumer of fuel ethanol. Ethanol gasoline was first introduced in California in the 1930s because of the 1970s
