Experimental investigations using granular activated carbon (GAC) adsorption and then desorpted with microwave irradiation for toluene abatement are reported in this paper. The results indicated that For different kinds of catalysts, Cu0.33Mn0.67Ox/γ-Al2O3 had the highest catalytic activity. For toluene combustion, the temperature required for 99% toluene conversion was lower than 300°C. In combination process of microwave desorption with catalytic combustion, the toluene conversion was ranged from 92% to 99% and the optimum volume flow rate ratio of carrier and air was 1:1.

The present work deals with thermodynamic analysis of a R-134a/R-23 cascade refrigeration system to evaluate the maximum COP and the minimum temperature difference (DT) corresponding to , by considering different operating parameters. The operating parameters includes: the condensing () and evaporating temperature () of R-134a and the condensing () and evaporating temperature () of R-23. A computational model has been developed for the considered system to evaluate the and DT corresponding to based on the thermodynamic principles. A mutilinear regression analysis has been carried out to evaluate two correlations for calculating and minimum DT considering the above operating parameters. The exergy analysis of the system is also performed to determine the irreversibility losses of the system as well as for the components. It has been found that the total exergy destruction rate of the system is lower at minimum .
