流化萃取褐煤蜡新工艺将散式流态化技术用于液固萃取过程，以溶剂为动力，携带煤粒，实现流化连续萃取。

A new process of continuous solvent extraction for production of montan wax based on particulate fluidization technology was developed .

本文根据我省已获褐煤蜡化验资料，总结出它在煤层中的分布是很不均匀的。

This article makes a summary showing that the distribution of lignitic wax in coalbed is very irregular according to the known test data of lignitic wax in Yunnan .

而对褐煤蜡进行脱色研究，进一步深加工为颜色较浅的S蜡，扩大其应用范围，一直是国内外研究的热点。

Decolorization on lignite wax and further deep processing of lighter lignite wax , and expansion of its scope of application , have been a research focus at home and abroad .

褐煤蜡是一种稀缺矿产，是由有机溶剂从褐煤中提取的一种高熔点硬质蜡，初级产品呈黑褐色，简称粗蜡。

The lignite wax is a scarce mineral-a kind of hard wax of high melting point that is extracted by organic solvents from the lignite , whose primary product is dark brown , referred to as course wax .

叙述了用阴离子交换色谱和硅胶柱色谱分离褐煤蜡纯蜡中的游离酸、酯中酸、醇以及烷烃的方法。

The separation free fatty acids , acids in esters , alcohols and paraf-fins from pure waxes of Sulan ( Jilin Province ) and Xindian ( YunnanProvince ) montan wax by anion exchange and silica gel column chroma-tography is described .

强调了褐煤蜡的生产和热电联产是褐煤资源综合利用的重点，在此基础上兼顾其它矿产资源开发利用。

It is stressed that the production of lignite , and heat-power coordinated production are the focal points of comprehensive utilization for lignite resource ; on this basis , the exploitation and utilization of other mineral resources is given consideration to .

最后得出，凡煤化程度低、稳定组分高的褐煤，褐煤蜡含量一定是可观的。

The result obtained finally is that wherever the degree of coalification is lower and the content of stable components in lignite is higer , the content of lignitic wax is certainly considerable .
