Improved treatment of used cooking oil as feedstock for biodiesel production

生物柴油是一种环保燃料，可以从处理过的食用油（UCO）中生产。UCO处理包括从UCO中去除杂质。去除杂质可提高UCO和用其生产的生物柴油的质量。**此外，用于生物柴油生产的处理过的UCO必须不含有毒物质（例如甲苯和苯）。UCO中的有毒物质可能存在于生物柴油中，它们的存在是不可取的，因为生物柴油是一种环境友好的燃料。步行者工业公司通过将杂质吸附到分散的水滴上来去除油中的杂质。拟议的 ** 项目将通过使用添加剂来改善UCO中杂质的去除，这些添加剂促进杂质吸附到小水滴 ** 上，同时限制用水量。拟议项目还将防止在UCO处理过程中形成苯和甲苯 **。这一目标将通过控制处理温度以避免UCO降解和通过 ** 消除自由基来实现，自由基可以催化甲苯和苯的形成。

Biodiesel is an environmentally friendly fuel which can be produced from treated used cooking oil (UCO). UCO treatment involves**the removal of impurities from UCO. Removal of impurities increases the quality of the UCO and of the biodiesel produced with it.**Also, the treated UCO used for biodiesel production must be free of toxic substances (e.g. toluene and benzene). Toxic**substances in the UCO may be found in the biodiesel, and their presence is not desirable because biodiesel is an environmentally**friendly fuel. Walker Industries removes impurities from the oil by adsorbing them onto dispersed water droplets. The proposed**project will improve the removal of impurities from the UCO by using additives that promote their sorption onto small water**droplets, while limiting the volumes of water used. The proposed project will also prevent the formation of benzene and toluene**during the UCO treatment. This goal will be achieved by controlling the treatment temperature to avoid UCO degradation and by**eliminating free radicals, which can catalyze the formation of toluene and benzene.
