ABSTRACT

Global warming is getting more serious in recent years. To reduce the emission of CO2 is a major task nowadays. This research studies concentrating carbon dioxide from the flue gas of a power plant and from syngas after water gas shift reaction by pressure swing adsorption (PSA) process, so that the concentrated carbon dioxide can be captured to reduce the greenhouse effect. Zeolite 13X is used as adsorbent in this study. In the beginning of this study, the experimental adsorption isotherm data were regressed to obtain the parameters of Langmuir-Freundlich isotherm. Then the mass transfer coefficient of linear driving force (LDF) model were calculated by theory and verified by breakthrough curve experiments. At the end of this study, both dual-bed six-step PSA process for syngas (41.4% CO2, 1.3% CO, 57.3% H2) feed and three-bed twelve-step PSA process for flue gas (15%CO2, 85%N2) feed were studied to find the optimal operating conditions.
