Abstract
1. An investigation was made of the catalytic transformation of nonane over two samples of 0.5% platinumaluminum silicate catalyst differing in specific surface at 360–450° under a hydrogen pressure of 10 atm in a flow system. 2. It was found, as in previous work, that the extent of hydrocracking of hydrocarbons diminishes considerably with reduction in the specific surface of the catalyst. 3. The conditions were found for the isomerization of nonane into branched C9 paraffins in yields of up to 54%. Over a catalyst of specific surface 320 sq. m/g (K-1) this yield was reached at 380°, and over a catalyst of specific surface 60 sq. m/g (K-2) this yield of branched C9paraffins was obtained at 450°. Under these conditions the total yields of hydrocracking products were 45.7% over Catalyst K-1 and 25.3 over Catalyst K-2.
