High Pressure Alkylation of Isobutane with Propylene

Free Radical Alkylation of Isobutane with Ethylene

“…• Only the halogen compounds showed activity. This was a rather surprising development, as in other studies using halogen compounds (9,75) only initiating activity was reported.…”

The Working Up of Lower, Normally Gaseous Paraffins and Mono-Olefins to Give Carburettor Fuels

“…The curves in Figs. [72][73][74][75] show the situation in the thermal polymerization of ethylene and propene at 35,70,140, and 210 atm pressure as functions of the reaction time and temperature with respect to the formation of liquid reaction product. These liquids were then subjected to column distillation (HEMPEL column).…”

“…The most important process at the present time for the manufacture of iso-octane consists in the alkylation of isobutane with KNAP et al [72] have again made a detailed investigation of the highpressure alkylation of isobutane with propene in the presence of homogeneous catalysts. They worked in the gas phase at 400° and pressures of 280 to 1050 atm in the presence of l } 2,3-trichloropropane or 1,2-dichloropropane.…”

Steel-Catalyzed Hydrogenation of Carbon Monoxide and Dioxide

“…In the literature little has been reported on the design, and operation of continuous high pressure pilot plants at the extreme conditions required for this study. The major portion of high pressure pilot plant design and operating experience available is reported by the Bureau of Mines staff (6, 18, S3, 24), although other continuous installations have been described (14,17,20,22). However, few of these have been designed for pressures above 10,000 lb.…”

“…Three units for operation above 10,000 lb./sq. inch (14,17,20) have been designed for service at 500°C. or higher; but the only instance of closure operation at the high temperature is that reported by Sliepcevich and Brown (20).…”
