Coal Gasification - an overview | ScienceDirect TopicsDeze pagina vertalen

Coal-gasification is a very important process involved in the production of chemical fertilizers, energy and many intermediate chemical products. As has been mentioned, the Koppers–Totzek coal-gasifier is an instance of the earliest application of impinging streams, applied industrially as early as 1952 [ 4, 145 ] although the term "Impinging Streams" was not used at that time.

Coal Carbonization for Coke Production – IspatGuruTraduire cette page

Coal Carbonization for Coke Production. Coal carbonization is the process by which coal is heated and volatile products (liquid and gaseous) are driven off, leaving a solid residue called coke. Carbonization of coal involves heating coal to high temperatures either in the absence of oxygen (O2) or in control quantity of O2. A gaseous by-product referred to as coke oven gas (COG) along with ...
