The vision of the proposed research is to develop activated carbon adsorbents and system models to improve the efficiency, flexibility and operability of IGCC processes . Novel activated carbon (AC) adsorbents prepared from resin precursors have the ability to be tailored to control both their CO2 adsorption capacity and isotherm shape. As a result, they offer significant advantages over solvent-based systems for the pre-combustion capture of CO2 in integrated combined cycle gasification (IGCC) processes in terms of cost and flexibility. The research will focus on gaining a fundamental understanding of how the porosity and surface functionality of resin-derived carbons, both in bead and monolith forms, controls their CO2 adsorption under actual process conditions in the presence of moisture and other gases. It is likely to achieve high CO2 removals in IGCC, more than one bed will be needed operating at different pressures. As a result adsorbents displaying high uptakes at low partial pressures (<5 bar) of CO2 will also be investigated. Indeed adsorbents displaying high uptakes at low partial pressures will also find applications in post-combustion capture and selectively removing CO2 from blast furnace gas during iron making. In parallel, the project will also consider how the unique performance of the AC sorbents for CO2 capture will improve the operability of IGCC power plants. Comparisons of emissions, resource requirements and costs with varying levels on CO2 removal via adsorption will be made on a systematic basis allowing different design options and control strategies to be devised, in order to minimise the effects of CO2 capture upon the overall process efficiency. In the research programme, the results from the first theme on the efficacy of the various ACs will be used as the design basis in the second theme on modelling the performance of IGCC plants. The proposal brings the balanced expertise together from five academic institutes to increase our understanding of AC adsorbents for pre-combustion capture and how they will improve the operability and flexibility of IGCC plants. The internationally recognized capability for CO2 adsorbents and power plant control at Nottingham and Birmingham and the complementary stengths of the Institute Coal Chemistry (ICC) and Tsinghau Univeristy make it logical for the partners to combine their strengths to address more effective capture of CO2 in IGCC and the implications of this on overall plant operation. Regarding the Chinese partners, Tsinghua have studied the IGCC process for over 10 years and they have developed the first complete simplified IGCC dynamical mathematical model and simulation program). ICC CAS have been involved in may aspects of gasification and are already working with the UoN on active carbons for post-combustion capture (ICUK award). In relation to the Call, this proposal addresses both:(i) New technologies based on material advances(ii) Modelling and simulation and of capture plants employing the advanced materials

拟议研究的愿景是开发活性炭吸附剂和系统模型，以提高 IGCC 工艺的效率、灵活性和可操作性。由树脂前体制备的新型活性炭（AC）吸附剂能够定制以控制其二氧化碳吸附能力和等温线形状。因此，在成本和灵活性方面，它们在集成联合循环气化 (IGCC) 工艺中燃烧前捕获 CO2 方面比基于溶剂的系统具有显着优势。该研究将侧重于从根本上了解树脂衍生碳（无论是珠状还是整体形式）的孔隙率和表面功能如何在存在水分和其他气体的实际工艺条件下控制其二氧化碳吸附。 IGCC 很可能实现高二氧化碳去除率，需要不止一张床在不同压力下运行。因此，还将研究在低 CO2 分压（<5 bar）下表现出高吸收率的吸附剂。事实上，在低分压下表现出高吸收率的吸附剂也将在炼铁过程中燃烧后捕获和选择性去除高炉煤气中的二氧化碳方面得到应用。与此同时，该项目还将考虑用于二氧化碳捕获的交流吸附剂的独特性能将如何提高 IGCC 发电厂的可运行性。将在系统的基础上对不同水平的吸附去除二氧化碳的排放、资源需求和成本进行比较，以便设计不同的设计方案和控制策略，以尽量减少二氧化碳捕集对整体工艺效率的影响。在研究计划中，第一个关于各种空调功效的主题的结果将用作第二个关于IGCC工厂性能建模的主题的设计基础。该提案汇集了五个学术机构的均衡专业知识，以加深我们对用于燃烧前捕集的交流吸附剂以及它们如何提高 IGCC 工厂的可操作性和灵活性的了解。诺丁汉和伯明翰在二氧化碳吸附剂和发电厂控制方面的能力得到了国际认可，煤炭化学研究所 (ICC) 和清华大学的优势互补，使得合作伙伴合乎逻辑地结合各自的优势来解决 IGCC 中二氧化碳更有效的捕集问题，以及这对整个工厂运营的影响。中方合作伙伴方面，清华大学对IGCC工艺进行了10多年的研究，开发出了第一个完整的简化IGCC动态数学模型和仿真程序。 ICC CAS 参与了气化的多个方面，并且已经与 UoN 就用于燃烧后捕集的活性炭进行合作（ICUK 奖）。就该呼吁而言，该提案涉及：(i) 基于材料进步的新技术(ii) 建模和模拟以及采用先进材料的捕集工厂
