摘要
本文采用低毒低价格的萃取剂,对黑龙江宝清褐煤进行提蜡实验,大大降低了生产过程的毒性和成本,并得出宝清褐煤中蜡含量在6%~10%(干基),是国内珍贵的富蜡煤资源。宝清粗蜡中树脂含量超过40%,可根据市场产品需求,对树脂进行分离,褐煤蜡产品满足工业技术指标要求。宝清褐煤生产褐煤蜡,具有较强的工业开发经济性。
In this paper,the low toxicity and low price extractant was used to extract wax from Baoqing lignite in Heilongjiang province,which greatly reduced the toxicity and cost of the production process.It was concluded that the wax content in Baoqing lignite was between 6%and 10%(dry base),which was a precious waxy coal resource in China.The resin content in crude wax of Baoqing is more than 405.According to the market demand,lignite wax can meet the requirements of industrial technology.The production of lignite wax from Baoqing lignite has strong industrial development economy.
