The application of novel solid materials in an integrated gasification and calcium looping technology: CO2 capture and energy production

加拿大的能源资源基础包括大量的化石燃料。然而，由于这些燃料的环境足迹，特别是温室气体（GHG）的排放，包括二氧化碳（CO2），这些燃料的回收和用于发电正受到越来越多的审查。在工业过程中捕获二氧化碳的一种常用方法是用胺类溶剂进行湿式洗涤。然而，这会导致热力学效率的严重损失，并且不太可能在大规模上具有成本效益。因此，最近人们对捕集二氧化碳的干法产生了相当大的兴趣。拟议研究的总体目标是开发一种新的综合气化方法，将气化与新创建的固体吸附剂相结合，为二氧化碳捕获提供可行的解决方案。拟议的解决方案将解决阻碍二氧化碳捕获领域变革创新的主要挑战。

Canada's energy resource base includes large amounts of fossil fuels. However, the recovery of these fuels and their use to generate electricity is coming under increasing scrutiny due to their environmental footprint, particularly in the emission of greenhouse gases (GHG), including carbon dioxide (CO2). One of the common means of capturing CO2 in industrial processes involves wet scrubbing with amine solvents. However, this causes a serious loss in thermodynamic efficiency and is unlikely to be cost-effective on a large scale. As a result, there has recently been considerable interest in dry processes for the capture of CO2. The overall objective of the proposed research is the development of a novel integrated approach to gasification, whereby gasification is combined with newly created solid sorbents to provide viable solutions for CO2 capture. The proposed solution will address major challenges that hinder transformative innovation in the area of CO2 capture. This research is a collaborative project involving academia, government and industry in pursuit of critical fundamental knowledge and application related to CO2 capture. Four research themes will address the challenges and gaps that currently exist: 1) material development, 2) thermochemical process development, 3) comprehensive CFD and process modelling, and 4) pilot-plant studies. The outcomes of this research will be the successful transfer of knowledge for the commercialization of a CO2 capture process, resulting in a major scientific breakthrough. The proposed research will benefit Canada's economy, energy and environment. The expected outcome of this work will benefit the environment through the reduction of GHGs released into atmosphere and potential impact on the legislative policies related to GHGs and a positive impact on the economy through sustainable production of hydrogen and training of highly qualified personnel for Canada's natural resources and energy sectors.
