Characterization of the catalysts indicated that a defect-free H-ZSM-5 membrane had been constructed successfully on the Co/SiO2 surface. The smaller Co/SiO2 pellets were favorable for zeolite capsule growth under the same synthesis conditions. Zeolite capsule catalysts, especially the catalysts with smaller pellet sizes, had a higher isoparaffin selectivity compared with conventional FTS Co/SiO2 catalyst and mixed catalyst of Co/SiO2 with H-ZSM-5 zeolite.", pages = "771-779(9)", url = "http://www.ingentaconnect.com/content/vsp/rci/2008/00000034/F0020008/art00016" doi = "doi:10.1163/156856708786189384" }
