چکیده
|
The extent of side reactions in propane dehydrogenation over pt-sn/al2o3 catalyst was studied. catalytic test runs were carried out in a fixed-bed quartz reactor under different operating conditions. the results showed that the extent of side reactions strongly depends on the operating conditions. the product distribution implied that single c-c bond rupture in propane is the predominant route for break-down of propane to the lower hydrocarbons. a beneficial effect of coke formation on propylene selectivity was observed at the expense of propane conversion, which can be attributed to the dilution effect of carbonaceous deposits on platinum sites.
