Partial Oxidation Partial oxidation (POX), or gasification, is a chemical reaction that occurs when a mixture of a hydrocarbon feedstock and a sub-stoichiometric amount of pure oxygen (O 2) are reacted together, producing a syngas stream with a typical H 2 /CO ratio range of 1.6 to 1.8. Here we will look at some of the important uses of coal in different areas both in industries and domestic use. It is a reaction of carbon monoxide of syngas mixture with steam in the presence of a catalyst as: This reaction is used to increase the yield of dihydrogen obtained from the coal gasification reaction as: It is a reaction of Nicola J. Wagner, ... J.C. van Dyk, in Applied Coal Petrology, 2008Pore Size and Surface Area of Chars The gasification rate of a coal is governed by its structure, with reaction gases penetrating particles and attacking carbon atoms and the resultant gases diffusing through the solid structure (Feng and Bhatia, 2003). 8â10 One of the first studies of kinetics gasification models was by Biba et al., 8 who have proposed a simplified kinetic gasification process model with five reactions for coal gasification. 11 turbines are applied to the IGCC. biomass by using the waste heat from a coal gasifier. Fuel gases such as CO, H 2, and CH 4 can be obtained by coal gasification. literature. Measurements of the intrinsic reaction rates of two Australian coal chars (made under laboratory conditions) with O2, CO2, and H2O at increased pressures (up to 30 atm) have been made using a pressurized thermogravimetric analyzer (TGA).
