A new CO2 sorbent was prepared from carbide slag, aluminum nitrate hydrate and glycerol water solution by combustion synthesis method. The effects of the sorbent preparation conditions (glycerol addition, combustion synthesis temperature, ratio of carbide slag to aluminum nitrate hydrate) and...

Since solid oxide fuel cells (SOFC) produce electricity with high energy conversion efficiency, and chemical looping combustion (CLC) is a process for fuel conversion with inherent CO2 separation, a novel combined cycle integrating coal gasification, solid oxide fuel cell, and chemical looping...

The objective of this study is to develop a new low-cost, highly selective, and stable sorbent based pre-combustion CO2 capture. A high surface area titanium oxide (TiO2) prepared by a template method and amine modified TiO2 (M-TiO2) were investigated for CO2/CH4 adsorption at conditions...

The objective of this research was to develop a new high-performance CO2 adsorbent with a simple method. Amine hybrid resorcinol–formaldehyde/silsesquioxane composite aerogel (AH-RFSA) was developed through polymeric sol–gel process and supercritical drying (SCD) technique. CO2 adsorption...

Over the last decades, fighting global warming has become the most important challenge humanity has to face. Therefore technologies of carbon dioxide capture, sequestration and recycling are equally important in order to tackle the global climate change stakes. Among recycling technologies,...

In this study, we estimate and analyze the CO2 mitigation costs of large-scale biomass-fired cogeneration technologies with CO2 capture and storage. The CO2 mitigation cost indicates the minimum economic incentive required (e.g. in the form of a carbon tax) to make the cost of a less carbon...

This paper presents a novel approach to recover energy from mineral carbonation process, one of the CCS (carbon capture and storage) technologies, to reduce its additional energy demand and reports the feasibility of integrating a carbonation process with an existing power plant for reducing CO2...

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...

The biggest technical barrier to full scale deployment of absorption technology for post-combustion carbon capture in electric power plants is the high energy consumption for solvent regeneration. This paper presents a new application of ejectors to upgrade external waste heat for the purpose of...

An advanced oxy-fuel hybrid power system (AHPS) is proposed in this paper. Solar thermal energy is used in the AHPS to produce saturated steam as the working fluid, and natural gas is internally combusted with pure oxygen. It is in configuration close to the zero emission Graz cycle. The...
