中文摘要 | 收集二氧化碳並再利用是二氧化碳減量的有效方法,其中收集二氧化碳目前最有效的方法是使用以醇胺為基本吸收物質的化學吸收劑,但仍需研製抗腐蝕性更佳,再生耗能更低的吸收劑,及搭配更具效率的吸收器,另外,以醇胺分子對奈米級二氧化矽進行表面改質的新型吸附劑亦是相當具有潛力的。而二氧化碳因無毒,可再生等特性使其具有多方面的再利用價值,其中超臨界二碳可望在乾洗業、半導體晶片清洗、化學反應溶劑等方面得以廣泛應用,而使用二氧化碳作為化學品生產的起始材眼,以及應用光觸媒,重組反應等技術以較環保的方式產生新能源,都能在環保議題之外亦可造就新的經濟型態。以超重力通生產奈米碳酸鈣在橡膠、紙、建材等方面具有重要應用,國內已可量產,但對於下游工廠的直接應用則有待開拓。另外利用藍綠藻生物固定二氧化碳,若能結合附帶的經濟效益如生化塑膠的開發等,則更能在二氧化碳減量的任務中扮演一定的角色。 |
英文摘要 | Capture and reuse of carbon dioxide are the most important tasks to reduce the concentration of carbon dioxide in atmosphere. Capturing carbon dioxide with amine-based absorbents is the most efficient method nowadays. However, the efficiency is not high enough, also amine-based compounds have serious problem on corrosion of stainless steel. To develop and absorbent with better anti-corrosion ability and less energy to regenerate the absorbent is the main research target. Nanoporous-silica adsorbents surfact-modified by amine-bearing molecules are expected to be the candidates. Carbon dioxide is a cheap, nontoxic and renewable feedstock, and can be reused in a environmentally benign way, and provide economic benefit. Supercritical CO2 show potential applications in dry-cleaning, chip-cleaning and organic solvent replacements. Carbon dioxide is a candidate to produce valuable chemicals like polycarbonate, and with some advanced technology it can be used as a new energy and dry-reforming technology. New catalyst system with high-gravity technique. Microalgae biofixation will play an important role with exploration of high-value byproduct like bioplatics. |
