This proposal addresses Topic 4 in the Call: New innovative CO2 capture technologies. The proposed research will address using synthetic zeolites obtained from fly ash to support impregnated and immobilised amines to facilitate CO2 post-combustion capture (PCC) in both coal and natural gas power plants. One of the barriers to the widespread implementation of CO2 in power plants is the energy cost associated with solvent regeneration in the most mature PCC technology, amine scrubbing, which will be even greater for gas-fired power plants because of the lower CO2 concentration, higher O2 concentration and higher flue gas flow rate compared to similar sized coal-fired power plant. Hence, alternative or second generation PCC technologies need to be developed that have the potential to lower this energy penalty and also have lower capital and operating costs. Solid adsorbent looping technology (SALT) is a novel, potentially low-cost that can overcome the main drawbacks of amine absorption. The technology relies upon adsorbents that can achieve high CO2 uptakes at relatively low temperatures with short residence times. Amines either impregnated or immobilsed on mesoporous materials, particularly aluminosilicates, have been found to be particularly effective.In the proposed research, zeolites produced from fly ash will be optimised for PCC as a route that will considerably reduce the preparation costs for basic adsorbents. The project will combine the respective strengths of MEERI/Lublin and the University of Nottingham in zeolite synthesis and developing basic adsorbents for PCC. The zeolites will be produced at Lublin on a scale of several kilograms to facilitate testing in a fluidised bed with real (gas-fired) flue gases at Nottingham. The production cost is estimated to be ca. 1 euro/kg of zeolite, which is considerably lower than using silicas and zeolites produced from traditional sources. The successful outcome of the proposed research will contribute to making SALT a more cost-effective process for PCC.

该提案涉及征集中的主题 4：新型创新二氧化碳捕获技术。拟议的研究将解决使用从飞灰中获得的合成沸石来支持浸渍和固定胺，以促进煤炭和天然气发电厂中二氧化碳燃烧后捕获（PCC）。在发电厂广泛应用二氧化碳的障碍之一是在最成熟的 PCC 技术（胺洗涤）中与溶剂再生相关的能源成本，这对于燃气发电厂来说会更大，因为二氧化碳浓度较低，较高与类似规模的燃煤电厂相比，氧气浓度更高，烟气流量更高。因此，需要开发替代或第二代 PCC 技术，该技术有可能降低这种能源损失，并且还具有较低的资本和运营成本。固体吸附剂循环技术（SALT）是一种新颖的、潜在的低成本技术，可以克服胺吸收的主要缺点。该技术依赖于能够在相对较低的温度和较短的停留时间下实现高二氧化碳吸收的吸附剂。人们发现，浸渍或固定在介孔材料（特别是铝硅酸盐）上的胺特别有效。在拟议的研究中，将从飞灰生产的沸石用于 PCC 进行优化，作为一种路线，将大大降低碱性吸附剂的制备成本。该项目将结合MEERI/卢布林和诺丁汉大学在沸石合成和开发PCC基本吸附剂方面的各自优势。这些沸石将在卢布林以公斤级生产，以便于在诺丁汉使用真实（燃气）烟气在流化床中进行测试。生产成本估计约为。 1 欧元/千克沸石，远低于使用传统来源生产的二氧化硅和沸石。拟议研究的成功结果将有助于使 SALT 成为 PCC 更具成本效益的过程。
