摘要

本研究利用一新技術製備氨修飾的吸附劑已利用於二氧化碳吸收。二氧化矽為本研究所選用的載體，經Tetraethenylpentamine (TEPA)修飾後用於捕捉二氧化碳，此新製程有別於傳統方法，可以在很短的時間內製成吸附劑，請也擁有很好的二氧化碳吸附性能。
本研究利用紅外光譜儀及質譜儀，搭配程溫控制吸收來觀察本實驗所製成之樣品性能。此外，本研究也針對含水及不含水的環境對二氧化碳捕捉做進一步研究。
經過本研究之觀察，二氧化碳以多層吸附於吸附劑被進一步證實，且二氧化碳雨水之間的競爭吸附情形也進一步被研究。

A new technique to prepare adsorbent for CO2 capture was applied in this study. Silica was selected to be support as the adsorbent and Tetraethenylpentamine (TEPA) was syringed on it to be the sorbent. It allowed a sample to be in few minutes and also presented well performance. A relatively lower regeneration temperature was be used in this study to renew the adsorbent.
In this study, by observation of in situ infrared (IR) spectra and temperature programmed desorption (TPD), CO2 was found to adsorb each other in multiple layers through hydrogen bonding. In present water environment, substantial spacial barrier produce to effect CO2 adsorption.
On the aspect of competitive adsorption between CO2 and water is also study by IR spectra, which CO2 adsorbed on TEPA-treated silica earlier than water.
