Abstract
Synthesis, characterization and adsorption properties of propane/propylene on mesoporous SBA-15 are reported. This material was also used as high surface area material for silver deposition to enhance propylene adsorption improving selectivity towards the olefin. Two different silver loadings were tested: Ag/SiO2 = 0.5 and Ag/SiO2 = 1.0. With the lower silver content, better selectivity and amount adsorbed was obtained. Preliminary studies were done for the use of this adsorbent in Vacuum-Pressure Swing Adsorption (VSA-PSA) units. With a four-step cycle comprising feed, pressurization, rinse and blowdown recovery of 97% propylene with chemical grade purity (91%) was obtained and also fuel grade HD-5 propane at high pressure. If higher propylene purity is required, a five-step cycle has to be used (pressurization, feed, rinse, co-current depressurization to intermediate pressure and counter-current blowdown). In this case, purity of 99% was obtained with 63% recovery. © 2005 Springer Science + Business Media, Inc.
