Influence of microbial transformation on lignite briquette's waterproof property

This paper discusses the problems and disadvantages in ammonia/urea industry in China,reveals current situation of shaped coal technology,analyzes the reasons causing oxygen-rich air continuous process failing popularized in the industry.

The origin of the coking waste slag,its properties and course of development are introduced and particularly the process for producing the shaped coal out of the coking waste slag described and effects of utilization of the shaped coal out of the waste slag for coking purpose on the quality of coke as well as the economical efficiencies analyzed.

Counting many defaults that exist in the processes of sludge treatment,this paper first presents a tentative plan and method about to make shaped coal with coal and carboniged dewater sludge.
