中高溫捕碳劑再生與驗證技術開發研究

Abstract

本計畫目的為建立已有的Ca-Al-CO3¬ LDH系統中高溫捕碳劑與相關Mesoporous 含高鈣成份中孔洞結構的材料製程，可用於吸附及分離中高溫二氧化碳，以配合本所示範系統建立之技術。由於中高溫捕碳技術有二項主要之技術瓶頸：(1)量產技術，利用化工製程建立可自動化之量產程序，此部份可由研究機構發展。另一項評估指標為再生技術即系統之穩定性(Durability)，包括再生技術與熱回收等，由於涉及複雜之材料設計、最佳化及改質等技術，其中隱含較為繁複與艱深之學理，如化學程式與熱動力學等。因此本計畫將利用與核研所開發之捕碳劑，進行材料改質研究，使性能優化並研究重要之高溫穩定性與再生程序，來配合提供後續kW級捕碳系統與示範系統之使用，以落實計畫目標。

In this works, development of high temperature Ca-Al-CO3 LDH and mesoporous CaO oxide for CO2 capture. As the high temperature CO2 capture has two main bottlenecks of the technology, including (i) automated processes by chemical engineering programed, and (ii) the assessment of renewable technologies for system stability, including regeneration technologies and heat recovery. As the complexity of the materials involved in the design, optimization and modification techniques, which implies more complicated and difficult of theoretical, such as chemical and thermal dynamics programed. Therefore, this project will use sorbent by INER with modification of materials research, performance optimization, high temperature stability, and regeneration process to provide the KW-class system.
