MCM-22 zeolites were synthesized and characterized by XRD, FTIR, TG, SEM, EDX, textural analysis by N2 physisorption and NH3-TPD. The MCM-22 zeolites have presented good crystallinity, high surface areas and a decreased amount of acid sites and strength with increasing SiO2/Al2O3 ratio was observed. The glycerol conversion and acrolein selectivity increased with increasing reaction temperature from 280 °C to 320 °C on MCM-22 (30) catalyst. As long as the concentration of glycerol solution was in the range from 10% to 36.6%, there was no noticeable difference in the glycerol conversion but the acrolein yield increased with water amount in the feed. The glycerol conversion and selectivity to acrolein at 320 °C using glycerol feed of 36.6% during 10 h of reaction decreased in the following order: MCM-22 (30) > MCM-22 (50) > MCM-22 (80). This result shows that glycerol dehydration to acrolein is strongly dependent on the acid sites density and external surface area of the zeolite MCM-22.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-05-13T12:10:23Z No. of bitstreams: 1 1-s2.0-S1387181113003569-main.pdf: 1019454 bytes, checksum: 48e50b885b940acf72ae7e8148c3e7a6 (MD5)Made available in DSpace on 2014-05-13T12:10:23Z (GMT).
