Реферат:
Kinetics of CO2 methanation reaction over the commercial nickel catalyst NKM-2V was studied in a perfectly mixed reactor at T = 250–350 °C. It has been shown for the stoichiometric mixture of CO2 and H2 that both the catalyst activity and CO2 conversion increase with temperature. The decrease in CO2:H2 ratio at T = 300 °C have led to the rise of CO2 conversion to methane. The composite material K2CO3/Al2O3, which is a promising solid absorbent for direct CO2 capture from ambient air, has been synthesized and studied in the temperature-swing adsorption cycles. It has been shown that the increase in the adsorber temperature from 200 to 325 °C during the thermal regeneration step enhances the utilization extent of the composite sorbent in the cycle with the total CO2 uptake rising from 1.9 to 4.4 wt.%. The process combining thermal regeneration of the composite sorbent in hydrogen atmosphere at T = 325 °C and CO2 methanation reaction over the commercial nickel catalyst NKM-2V at T = 425 °C has been studied using the catalytic reactor connected to the outlet of the adsorber. It has been demonstrated that it is possible to transform CO2 into methane with conversion >99%.
