A BRIEF REVIEW OF ENHANCED CO_2 ABSORPTION BY NANOPARTICLES

摘要

With the continuous release of CO _( 2 ) and other acid gases, the greenhouse effect becomes more and more serious, so it is more and more important to capture CO _( 2 ) . In this paper, the research status of nanoparticles enhanced CO _( 2 ) absorption and three basic properties of nanofluids, i.e., thermal conductivity, viscosity and convective heat transfer in recent years are introduced. At the same time, the enhancement mechanism of CO _( 2 ) absorption by nanofluids was studied in details. The effects of various factors on the enhancement of CO _( 2 ) absorption and the numerical calculation of mass transfer process were summarized. At present, there are few researches on the enhancement of CO _( 2 ) absorption, so the future research on enhanced CO _( 2 ) absorption will be a hot topic in this area.
