生物质燃料是作为从生物质资源生产的燃料的柴油的替代品。它通常被定义为来自植物油或动物脂肪的脂肪酸甲酯（FAME）。在欧洲国家，如德国和法国，生物柴油主要是由菜籽油商业化生产的，而在美国和阿根廷，大豆油更常用。在许多其他国家，例如日本和东南亚国家，不能用作食物来源的脂质可能是生产生物柴油燃料的更合适材料，因为从食用油生产生物柴油可能导致食用油价格上涨，从而增加一些食品的成本。因此，在这些国家，用过的食用油、榨油过程中的废水中所含的脂质、炼油过程中的副产品和麻风树等经济作物的原油可能是更有前途的材料。日本和东南亚生产生物柴油的原料具有共同的特点，它们含有大量杂质，游离脂肪酸（FFA）含量高。过热甲醇蒸汽（SMV）反应器是一种利用含游离脂肪酸的油脂原料（如废植物油和粗植物油）生产生物柴油的有前途的方法。在使用碱性催化剂的常规方法中，已知废植物油中含有的FFA与碱性催化剂如NaOH和KOH反应生成皂化产物并使其分解，因此需要在反应之前从原料中除去FFA。还需要在反应后除去碱性催化剂。在SMV反应器的情况下，可以省略反应前去除FFA和反应后去除催化剂的过程，因为它不需要催化剂。然而，尚未对使用SMV反应器从废弃植物油和其他非食用脂质生产生物柴油燃料的生产率进行详细研究。因此，本研究旨在考察使用SMV反应器从废弃植物油中生产生物柴油的产率。生物质燃料是作为从生物质资源生产的燃料的柴油的替代品。它通常通过使用碱催化醇解工艺作为源自植物油的FAME生产。这种碱性方法需要在反应过程之前进行脱酸过程和在反应之后进行碱性催化剂去除过程。这些过程增加了生物柴油燃料生产的总成本。针对传统碱催化醇解工艺存在的问题，提出了一种鼓泡塔过热甲醇蒸汽（SMV）法非催化醇解工艺。因此，本研究旨在探讨以植物油及其他油脂为原料，以鼓泡塔反应器为反应器，利用SMV法生产生物柴油的产率。
Biodiesel fuel is a replacement for diesel as a fuel produced from biomass resources. It is usually defined as a fatty acid methyl ester (FAME) derived from vegetable oil or animal fat. In European countries, such as Germany and France, biodiesel fuel is commercially produced mainly from rapeseed oil, whereas in the United States and Argentina, soybean oil is more frequently used. In many other countries such as Japan and countries in Southeast Asia, lipids that cannot be used as a food source could be more suitable materials for the production of biodiesel fuel because its production from edible oils could result in an increase in the price of edible oils, thereby increasing the cost of some foodstuffs. Therefore, used edible oil, lipids contained in waste effluent from the oil milling process, byproducts from oil refining process and crude oils from industrial crops such as jatropha could be more promising materials in these countries. The materials available in Japan and Southeast Asia for the production of biodiesel fuel have common characteristics; they contain considerable amount of impurities and are high in free fatty acids (FFA). Superheated methanol vapor (SMV) reactor might be a promising method for biodiesel fuel production utilizing oil feedstock containing FFA such as waste vegetable oil and crude vegetable oil. In the conventional method using alkaline catalyst, FFA contained in waste vegetable oil is known to react with alkaline catalyst such as NaOH and KOH generating saponification products and to inactivate it. Therefore, the FFA needs to be removed from the feedstock prior to the reaction. Removal of the alkaline catalyst after the reaction is also required. In the case of the SMV reactor, the processes for removing FFA prior to the reaction and catalyst after the reaction can be omitted because it requires no catalyst. Nevertheless, detailed study on the productivity of biodiesel fuel produced from waste vegetable oils and other non-edible lipids by use of the SMV reactor has not been examined yet. Therefore, this study aims to investigate the productivity of biodiesel produced from waste vegetable oils using the SMV reactor. Biodiesel fuel is a replacement for diesel as a fuel produced from biomass resources. It is generally produced as a FAME derived from vegetable oil by using alkaline catalyzed alcoholysis process. This alkaline method requires deacidification process prior to the reaction process and the alkaline catalyst removal process after the reaction. Those process increases the total cost of biodiesel fuel production. In order to solve the problems in the conventional alkaline catalyzed alcoholysis process, the authors proposed a non-catalytic alcoholysis process called the Superheated Methanol Vapor (SMV) method with bubble column reactor. So, this study aims to investigate the productivity of biodiesel produced from vegetable oils and other lipids using the SMV method with bubble column reactor.
