Product Details
常温常压加剂搅拌10-25分钟高凝点廉价棕榈油制取生物柴油技术
根据2005年中华人民共和国国家发改委、科技部、环保总局第65号联合公告,公布的《国家鼓励发展的资源节约综合利用和环境保护技术》260项,其中第41项“利用废动植物油生产生物柴油技术”明文规定:“该技术可将废油中的游离脂肪酸、脂肪酸三甘酯,在特制的催化剂条件下,在常温常压下与工业甲醇在同一容器内一步合成脂肪酸甲酯,再用复合处理液使游离油酸皂化分离,起到脱臭与降低酸值作用,获得酸值低于0.8mg/koH/g的生物柴油。该技术转化脂肪酸甲酯转化率在95%以上,所产生物柴油质量指标符合美国标准,达到国家0号柴油标准。”详见以下公告文件。国家三部(局)委联合发文对于鼓励发展的节能环保项目生物柴油已明文规定了其生产工艺条件:常温常压、特制的催化剂、在同一容器内一步合成、复合处理液等,这就给生产生物柴油提出了更高的要求,不但生物柴油的质量要达到国标,而且对生产方法也必须是常温常压,否则难以得到国家政策的支持和鼓励发展。也就是说我国目前广泛采用的加温、回流、减压蒸馏等非常温常压、非一步法合成的生物柴油的老工艺,即使产品能达到国标,其生产方法也不在国家鼓励发展的项目之内。
本技术是按照国家的规定常温常压下,以煎炸废棕榈油(指餐饮业煎炸过食物的废油),或者直接以廉价的棕榈油为原料,与工业甲醇在同一容器内一步合成脂肪酸甲酯生物柴油,然后用复合剂精制,其产品质量达到国家柴油标准。众所周知,棕榈油为饱和油脂,因为它含有50%的饱和脂肪,所以凝点较高,其规格一般可分为24度、33度、44度(熔点温度)几种,这为制取和使用生物柴油带来难度。但由于棕榈油的价格在植物油中最便宜,在经济上是有利可图的。目前据国内棕榈油市场价格3000-4000元/T,除去催化剂、添加剂、精制剂等助剂约100元左右(每吨油),水电工资等综合成本约每吨油80元左右,产率95%左右,吨油可获效益800元以上(按生物柴油售价4500-4800元/T计算)。主要设备为搅拌釜、反应釜、分离器等,容器材质为普通碳钢,主要设备投资20-30万元即可批量生产。现对外转让技术,有意者自备棕榈油样品,当场试验,保您满意。
