The mechanisms of chlorination of PbO, CdO, ZnO, and CuO by poly(vinyl chloride) (PVC) and sodium chloride (NaCl), including their reaction temperatures, pathways, and products, were studied and compared. It was found that PVC can chloridize the four oxides via different mechanisms, producing corresponding chlorides. The heavy metal oxides in PVC–PbO and PVC–CdO were chloridized by gas–solid reaction...
This paper presents a new approach to analytical modelling pyrolysis kinetics of oil shale based on Arrhenius equation which is inherently nonlinear allowing no exact analytical solution. The proposed method introduces an approximation which leads to a significant simplification of the closed-form solution and the calculation and allows for rapid estimates of kinetic parameters. The analytical model...
