Integrated Carbon Dioxide Capture and Utilization for the Production of CH₄, Syngas and Olefins over Dual‐Function Materials

Abstract

The massive emission of carbon dioxide produces the greenhouse effect and poses a threat to the survival of modern civilization. The search for new carbon management strategies has been at the forefront of scientific research over the past few decades. Integrated carbon dioxide capture and utilization (ICCU), which aims to capture CO2 and convert it in situ into high value‐added products or fuels, is considered to be more attractive and innovative than alternative strategies. This paper introduces the adsorption capacity and characteristics of solid sorbents at different operating temperatures. On this basis, the recent research on ICCU technology combined with methanation, the reverse water‐gas shift reaction, dry reforming of alkanes and dehydrogenation of alkanes over novel dual function materials is presented, and the development direction and future prospects of ICCU are discussed.
