چکیده

Integrated CO2 capture and utilisation via dry reforming of methane (ICCU-DRM) represents a promising profitable route for directly capturing converting from various sources. However, the influence realistic flue gas conditions on ICCU-DRM remains unknown challenging. Herein, we investigated presence H2O O2 in power plant integrated DRM using Ni10-CaO dual functional material (DFM). It is found that promoted kinetics capture, while oxidised Ni into NiO prohibited performance captured during DRM. Specifically, delay pre-reduction coverage catalytic sites by formed CaCO3 decreased process efficiency. The reduction would instantly generate hinder contact between CH4 Ni, resulting lower initial (DRM) ICCU. Due to occurrence decomposition DRM, following step produce CO gas, which could be problematic, owing carbon gasification reactions. An extra steam (CSG) after effectively remove most deposited by-produce syngas. Subsequently, small amount residue CSG preferentially combusted then CaO instead generating CO. This study demonstrates feasibility challenges under simulated provides potential insights future investigation deployment this process.

Flue gas treatment for CO2 capture

This report is in two sections: the first describes the flue gas and its treatment in post-combustion capture and the second covers the flue gas in oxyfuel combustion capture. The main components of the flue gas in pulverised coal combustion for postcombustion capture are CO2, N2, O2 and H2O, and air pollutants such as SOx, NOx, particulates, HCl, HF, mercury as well as other contaminants. The ...

Two novel oxy-fuel power cycles integrated with natural gas reforming and CO2 capture

Two novel system configurations were proposed for oxy-fuel natural gas turbine systems with integrated steam reforming and CO2 capture and separation. The steam reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel with oxygen as the oxidizer. Internal combustion is used, which allows a very high heat input temperature. Moreover, the turbine...
