生物燃料产业发展面临巨大压力

据美国《世界炼油商务文摘周刊》2015年3月23日报道,由于油价下跌及美国环保署（EPA）实施的可再生燃料标准（RFS）未及时修订,导致美国生物柴油贸易停滞不前,可再生燃料身份码（RINS）、燃料油交易量均下降,部分生物燃料生产商开始减产并关停工厂。目前,美国生物燃料生产商、

Biodiesel synthesis via metal oxides and metal chlorides catalysis from marine alga Melanothamnus afaqhusainii

This research article demonstrates the most comprehensive comparative catalytic study of different metal oxides and metal chlorides towards the methanolysis of triglycerides of marine red macroalga Melanothamnus alhqhusainii. CaO was found to be the most reactive metal oxide that yielded 80% biodiesel while ZnCI2 was the most reactive metal chloride that produced 60% biodiesel by mechanical stirring for 6 h at 100-110 ℃. The overall reactivity order of the catalysts was found to be CaO 〉 MgO 〉 Pb02 〉 ZnC12 〉 TIC14 〉 PbO 〉 HgC12 〉 ZnO 〉 AIC13 〉 SnCI2 〉 TiO2 whereas, CaCI2, MgCI2, A1203, HgO, PbCI2, MnO2, MnC12, Fe203 and FeCI3 were found to be non-reactive for transesterification of triglycerides. In addition, a detailed study of the screening of mobile phases and spraying reagents was conducted which showed that petroleum ether ： chloroform ： toluene （7：2：1 ） is the best mobile phase, whereas iodine crystals/silica gel is the best visualizing agent for the thin layer chroma- tography （TLC） examination ofbiodiesel. Biodiesel production was confirmed by comparative TLC examination. It was further supported by the determination of fuel properties of biodiesel, which were found to be similar to the standard limits of American Society for Testing and Materials （ASTM）,

油脂中远期涨势分析

总体上全球宽松货币政策的基调不会改变,热钱流动的趋势很难再度反转。热钱将继续流入中国,流动性过剩仍会推高商品价格。随着美元维持疲软、原油消费旺季的到来,油价有望重新回升至前期高点附近,2009年四季度仍有望创出年内新高。油脂类农产品具有能源属性,随着原油价格上涨。

库存易增难减豆油上方承压

4月11日当周油脂市场经历了冰火两重天。先是4月10日美国农业部月度供需报告超预期下调2013/2014年度美国及全球大豆结转库存预估,对豆油市场提供支撑。随后,马来西亚棕榈油局发布的数据显示,3月马来西亚棕榈油库存较2月增加3万吨至169万吨,而此前市场预期马棕油库存将继续下滑,数据公布之后,棕榈油大幅下跌,豆油也受此拖累振荡走低。
