Summary
-
1.
The catalytic conversion of normal nonadecane and of eicosane in the presence of 0.5% Pt—Al2O3, 0.5% Pd-Al2O3, 0.5% Pt- “gumbrin“, and 0.5% Pd- “gumbrin“ at 450‡ in a flow system under a pressure of 30 atm of hydrogen was studied.
-
2.
On catalytic treatment these hydrocarbons undergo profound changes in the direction of isomerization, dehydrocyclization and hydrocracking. The products of catalysis so obtained are characterized by a higher calorific value and a decrease in the temperature of solidification by 20–46‡.
-
3.
0.5% Pt-“gumbrin“ and 0.5% Pd-“gumbrin“ are more active catalysts in effecting the reactions mentioned than are 0.5% Pt-Al2O3 and 0.5% Pd-Al2O3.
