Catalysis by Pillared Clays

In each experiment 5 g of a 3.5 % solution of DHT in benzene and 0.2 g of catalyst in admixture with 2.0 g of carborundom were used. 

Hydroconversion of heptane (H2/ -C7 = 16) was carried out under temperature-programmed conditions over pillared beidellite, pillared montmorillonite, a ultrastable Y-zeolite, H-ZSM-5 and silica-alumina, all containing 1 wt% of Pt. The conversions of heptane over five catalysts are shown as a function of the reaction temperature. As shown in Fig. 3.59, pillared beidellite is more active than pillared montmorillonite, and the former is almost as active as the zeolites. Silica — alumina is the least active.
