CO

A new model of CO2 gasification has been developed in the Aspen Plus. The potential of microalgae (N. oculata) for CO2 gasification also has been investigated. The present gasification process utilizes the CO2 at atmospheric pressure as the gasifying agent. The steam is also injected to the gasification to enhance the H2 production. The composition of the producer gas and gasification system efficiency (GSE) are used for performance evaluation. It is found that the CO2 gasification of microalgae produces a producer gas with a high concentration of CO and H2. The GSE indicates that the process works at high performance
