This book presents a theoretical and experimental analysis of the solar thermal gasification of petroleum coke, focussing on thermodynamics, chemical kinetics and reactor design. The following main topics are included: (i) Equilibrium computation of the stoichiometric system of pet coke and steam at 1bar and 1300K. (ii) Rate laws for pyrolysis and reactive gasification with steam and carbon dioxide. (iii) Experimental determination of the rate constants using thermogravimetry. (iv) Experiments with a laboratory scale fluidized bed reactor heated by the ETHs high-flux solar simulator using...
