Abstract
Supercritical propane (SC-propane) was found to be an appropriate solvent to graft 3-aminopropyl triethoxysilane (APS) onto our own synthesized SBA-15 for CO2 capture. SC-propane grafting provides several advantages, including non-toxicity, low cost, less reaction time, and usability under wide ranges of pressure and temperature over toluene. Besides, SC-propane can be completely removed when pressure is released after grafting. In this study, the grafting in propane was carried out at the selected pressure and temperature. The grafting in SC-propane exhibited an improvement for amount of the grafted APS and CO2 adsorption capacity over those using the conventional toluene refluxing method.
