IOP Conference Series: Materials Science and Engineering
The upgrading process is intended to increase the calorific value of coal. The upgrading process can be applied to the process of coal briquettemaking. Generally, the manufacturing of low quality coal briquettes uses mechanical and heating methods in two different processes. In this study, the manufacturing of the briquettes uses the tools in aThe impact of coal upgrading on the thermal efficiency of coal use is discussed, and the countries where there could be the greatest impact are identified. • Heinz Termuehlen and Werner Emsperger: Clean and efficient coal-fired power plants, ASME Press, NY, 2003.

Optimization of coal-to-liquid processes; A way forward
As the world's largest consumer of coal, China is committed to developing a carbon–neutral coal industry. For this purpose, upgrading the carbon emission-intensive coal-chemical industries, such as coal-to-liquids (CTL) is imperative. This study develops a technical–economic framework to model and test four promising CTL upgrading processes.Froth flotation is the most effective method for fine coal upgrading. However, a low yield, developed porosity, and a large number of oxygen surface functional groups in fine low-rank-coal lead to low separation efficiency and necessitate the use of highly oily collectors (Jia et al., 2000, Yu et al., 2013). Achieving a satisfactory yield orClean low-rank-coal purification technique combining

Introduction At present, coal is the preeminent fuel of thermal power plant.One of the coal upgrading methods is selective coal agglomeration. The agglomeration process traditionally is performed in the stirred tanks and, because of its disadvantages, is not popular. As results from Table 1, the flotation machine was used for conditioning at 1100 rpm, then for high shear processing at 2100 rpm (emulsificationApplication of Flow Consecutor for coal upgrading

Comprehensive review on pyrolytic oil production, upgrading
Utilization of fuel oil from biomass (i.e., bio-oil) reduces emission of greenhouse gases. This paper discusses the different pyrolyis processes, physiochemical properties of pyrolysis products, upgrading techniques for safe storage and application in transportation and industrial activities. The production of bio-oil is challenging and There has recently been a resurgence in research into brown coal upgrading by slurrying and/or grinding followed by drying, e.g. Bassler, 1974, Woskoboenko and Stacy, 1985, Woskoboenko et al., 1988 and Johns et al., 1989. However, densification of Victorian brown coal by drying colloidal suspensions was first reported by Thwaites (1927).Briquetting Process an overview ScienceDirect Topics
