Samonosné pelety z (Al)-SBA-15
 Topka, Pavel ; Zub, Yu.L. ; Šolcová, Olga
Self-supporting pellets were successfully formed from SBA-15 and Al-SBA-15 powder without the addition of binder or plasticizer. Prepared self-supporting pellets maintained the porous structure of original powder. In comparison with parent sample, a decrease of mesopore surface area and mesopore volume up to 40 % was noticed in the case of pellets formed with the highest 17.7 MPa pressure. The Al-SBA-15 pellets prepared using 4.7 MPa forming pressure were enough mechanically stable to retain the structural integrity during batch alkylation of toluene with benzyl alcohol at 110 °C. The conversion reached with Al-SBA-15 pellets after 60 min of the reaction was about five times lower than that accomplished with powder Al-SBA-15.
