Advanced solid sorbent-based CO2 capture process

RTI International, Masdar, and Pennsylvania State University (PSU) are leading an effort to develop an advanced solid sorbent- based CO2 capture process for application to exhaust gas from various industrial sources – including coal-fired power plant flue gas. The technical and economic hurdles to solid sorbent CO2 capture are being addressed through transitioning a promising sorbent chemistry (based on supported amines) to a low-cost sorbent suitable for use in a fluidized-bed process. In parallel, a scalable circulating fluidized-bed process arrangement is being developed. Efforts have focused on improving sorbent stability and performance, converting sorbents to a fluidizable form, producing large quantities (100+ kg) of sorbent through scalable methods, and evaluating the viability of new process designs through bench-scale testing using simulated coal-fired flue gas.
