Title: Increasing the octane number of paraffinic gasoline blending stocks - by cyclising the paraffins followed by conventional reforming
Inventor: WILSON RAYMOND FREDERICK
IPC: B01J23/56
Filed: 1975-10-08
Abstract: The octane number of paraffinic (>=70% paraffins) gasoline blending components is increased by (1) cyclising the paraffins by contacting the feed with H2 in the presence of a catalyst comprising a noble metal (specifically Pt or Pd) on manganesia in an alumina gel matrix, and (2) reforming the cyclised effluent in the presence of a conventional Pt or Pt bimetallic reforming catalyst on an K2O3 or K2O3-contg. support. Pref. the catalyst for step (1) is produced by impregnating MgO with a soln. of a soluble Pt cpd. (specifically chloropletinic acid) and drying the impregnated powder prior to mixing it into the Al2O3 gel matrix. The noble metal may be stabilised with another metal (selected from Gp.

Title: Radioactive waste stored during decay in solid form - and used for heat generation in shielded vessels suitable for final disposal
IPC: G21F9/22
Filed: 1976-01-10
Abstract: A method of disposal of highly radioactive waste from nuclear power plants and the like, occurring in the form of a liq. slurry, consists of introducing the waste together with a solidification agent into a container of cast steel or grey cast iron; a surrounding shell of cast steel or cast iron is then cast around this to act both as a radioactive shield and as a mechanical protection to withstand all further transportation and loading stresses. The resultant shielded vessel, together with others of the same type, is then stored for a period as a heat source in a heat generating unit. After the radioactivity has decayed to the required low level, the containers are then removed to their final storage place. By comparison with the previous principle, in which the waste was stored for up to five years in liq. or slurry form, then for a further equivalent period in solid form before final disposal, the new method considerably simplifies the handling and eliminates several operations. Also, throughout the period of decay the decay heat can be utilised as a source, for example for water heating in a district heating system or the like.
