今后10年内,由于生产生物柴油(甲酯)和蔗糖聚酯时所产生的甘油大量增加,从而使世界甘油市场的紧张状况得以缓解。据美国某公司预测到1997年,这类甘油产量将是1993年的12倍,届时将有7万吨多余的甘油寻找市场销路。目前世界甘油总需求量在60万吨左右,世界甘油的产量虽然近年来随着东南亚脂肪酸、高级醇的增长,天然甘油的产量也表现出增长的势头,但仍然满足不了世界应用甘油的需求。 在1993年,世界甘油市场上,87％是天然甘油,其余为合成甘油。天然甘油中,37％为制皂工业的副产品皂化甘油,仅有1％是生产生物柴油(甲酯)和蔗糖聚酯的副产品甘油。 甘油的应用非常广泛,其用途已扩展到100多个应用领域,并且仍在发展之中。目前,甘油货源已经是
In the next 10 years, the production of biodiesel (methyl ester) and sucrose polyester will increase the amount of glycerol produced, which will ease the tension in the global glycerol market. According to a forecast from a U.S. company, the output of this type of glycerol will be 12 times that of 1993, and 70,000 tons of excess glycerol will be sold in the market. At present, the total global demand for glycerol is around 600,000 tons. Although the world’s output of glycerol has increased in recent years along with the growth of fatty acids and higher alcohols in Southeast Asia, the output of natural glycerol also shows a momentum of growth, but it still cannot meet the needs of the world’s application of glycerol. In 1993, 87% of the world’s glycerol market was natural glycerol and the rest was synthetic glycerol. Among natural glycerin, 37% are saponified glycerol, a by-product of the soap making industry, and only 1% are glycerol, a byproduct of the production of biodiesel (methyl ester) and sucrose polyester. Glycerol is widely used and its use has been extended to more than 100 application areas and is still under development. At present, the glycerin supply is already
