Additionally to Thar coal reserves, there are lignite coal reserves located in various regions of Pakistan i.e., Sonda Indus East, Lakhra and other areas of Sindh.

This paper describes a study undertaken to explore the use of a high volume of lignite coal fly ash (FA) as a replacement for Type I Portland cement (OPC) and a high volume of rice husk ash (RHA) as a replacement for fine aggregate in the production of self-consolidating concrete (SCC). OPC was partially replaced with 0%, 20%, 40%, and 60% …

The continuous consumption of high-quality coal and the increasing shortage of energy resources could result in further exploitation of inferior coal [2]. Lignite is mainly utilized in combustion, pyrolysis, and cooking, or it's dehydrated, dried and reused. However, the processes are more complex and produce pollutants [3,4].

1. Introduction. Coal gasification technology, an efficient way to achieve the cascade conversion of coal resources, has made remarkable contributions to the sustainable development and clean utilization of fossil fuels [1], [2].However, along with coal to gas, oil, olefins, glycol, and other products, a large amount of coal gasification …
