A short review of catalysis for CO2 conversion

Current progress on zeolite membrane reactor for CO2 hydrogenation

“…CO2 has already been used in few industrial processes such as synthesis of urea and its derivatives, salicylic acid, and carbonates. This is primarily because CO2 is thermodynamically stable so that high energy substances or electroreductive processes are required to convert CO2 into other chemicals [8][9][10].…”

“…CO2 has replaced CO as an alternative feedstock for methanol production. Methanol synthesis is also considered an effective way for CO2 utilization [8,11].…”

“…Actually, elevated reaction temperature (such as higher than 513 K) facilitate CO2 activation for methanol formation [8] [39]. Moreover, parallel side reactions may occur hence incurring the formation of some byproducts such as CO, hydrocarbons, and higher alcohols [12].…”

“…There have been some reviews related to CO2 conversion and catalytic hydrogenation of CO2 [5,7,8,[31][32][33][34][35][36][37][38][39][40][41][42][43]. However, to the best of our knowledge, there are no specific reviews towards selective layer progress related to CO2 hydrogenation membrane reactor.…”

“…As a result, the increased availability of CO2 is likely to drive its cost down, so that heterogeneous catalysis could be used to convert CO2 to various chemicals such as methane, methanol, formic acid and dimethyl carbonate (Aresta et al, 2007;Ma et al, 2009). Of course, CO2 is thermodynamically very stable and the main challenge in converting it to other organic products is providing the free energy needed.…”
