Coal Blending an overview ScienceDirect Topics

Many coal blending theories have been proposed for producing coke of a specific targeted quality by blending various kinds of coals. For example, Jo (1965) considered that coal consists of two components, a fibrous component and a caking component, and that increasing the strength of fibrous component (coal rank) and the addition of a suitable amount of caking component (caking property) are

Blending Fuel an overview ScienceDirect Topics

Blending is an attractive way to valorise cheaper feedstocks into biodiesel. Feedstock blending (before transesterification) may be carried out by the biodiesel producer, or FAME blending by the diesel producer or dispencer. The most important part of product quality after good feedstock is to get the final product blended correctly.

Interrelationship of coal grinding properties and coal

The Hardgrove grindability index (HGI) is a widely used coal-quality parameter with applications in coal mining, beneficiation, and utilization. An understanding of the petrology of the coal is fundamental to understanding the validity of the HGI in the given application. The HGI varies with coal rank, increasing (greater ease of grinding) with increasing rank through the high-volatile
