Advanced carbon capture materials

加拿大认识到，“二氧化碳占所有温室气体总影响的75%，是人类引起的全球变暖和相关气候变化的主要原因”。2018年，政府间气候变化专门委员会（IPCC）敦促在能源、工业、建筑、交通和城市方面进行快速、深远和前所未有的变革，将全球变暖限制在1.5 °C，要求到2030年将人为二氧化碳排放量减少45%。捕获和封存/利用大点源的CO2被认为是遏制温室气体排放的最有效战略之一。 在渥太华大学，我们发现并申请了一系列强大的吸附剂材料的专利，这些材料具有无与伦比的可逆吸附（捕获）工业气体中的CO2和解吸（释放）纯CO2的能力，用于封存或利用。 因凡提斯公司（Burnaby，BC）是一家领先的加拿大清洁技术公司，开发了一种革命性的工艺，使用独特结构的吸附剂超快速吸附和解吸二氧化碳。他们专有的VeloxoTherm工艺由一个旋转组件组成，允许整个吸附-解吸循环在一分钟内分三步进行。材料首先暴露于含CO2的气体混合物（吸附），然后进行蒸汽汽提（用于回收纯CO2）和空气冷却，然后在完全旋转后开始新的循环。VeloxoTherm工艺的效率主要取决于吸附剂，包括它吸附二氧化碳的量和速度，以及它在蒸汽和空气中的稳定性。因此，该项目的总体目标是在渥太华大学开发最先进的CO2吸附剂，并将其集成到Inventys的VeloxoTherm技术中。

Canada recognizes that "carbon dioxide, representing 75% of the overall impact of all greenhouse gases (GHGs) is the main cause of human-induced global warming and associated climate change". In 2018, the Intergovernmental Panel on Climate Change (IPCC) urged rapid, far-reaching and unprecedented changes in energy, industry, buildings, transport and cities, to limit global warming to 1.5 °C, requiring a 45% reduction in anthropogenic CO2 emissions by 2030, relative to 2010 levels. CO2 capture and sequestration/utilization from large-point sources is recognized as one of the most effective strategies to curb GHG emissions. At the University of Ottawa, we discovered and patented a family of powerful adsorbent materials with unparalleled ability to reversibly adsorb (capture) CO2 from industrial gases and desorb (release) pure CO2 for sequestration or utilization. Inventys Inc. (Burnaby, BC), a leading Canadian clean-tech company, developed a revolutionary process for ultra-rapid adsorption and desorption of CO2 using uniquely structured adsorbents. Their proprietary VeloxoTherm process consists of a rotating assembly that allows the whole adsorption-desorption cycle to take place in three steps within one minute. The material is first exposed to the CO2-containing gas mixture (adsorption) followed by steam stripping (for recovery of pure CO2) and cooling in air, before starting a new cycle after a full rotation. The efficiency of the VeloxoTherm process depends primarily on the adsorbent, including how much and how fast it adsorbs CO2, and how stable it is in steam and in air. Hence, the overarching objective of this project is to develop state-of-the-art CO2 adsorbents at the University of Ottawa to be integrated in Inventys' VeloxoTherm technology.
