Title: Improvements relating to the catalytic reforming of petroleum hydrocarbons
IPC: C10G21/00
Filed: 1955-09-23
Abstract: A process for catalytically reforming a petroleum feedstock such as a naphtha fraction comprises contacting the feedstock with liquid sulphur dioxide, preferably at -30 to +20 DEG  F. in the proportion of 50-150 volumes per 100 volumes of naphtha, to produce an aromatic extract and a raffinate, catalytically reforming the raffinate, contacting the reformate with liquid sulphur dioxide, preferably at -30 DEG  to +20 DEG  F. in the proportion of 200-400 volumes per 100 volumes of naphtha, to produce an aromatic extract of the same aromatic content as the previously mentioned aromatic extract and a raffinate which is recycled to the reforming stage.  The extraction processes may be carried out at the same temperature using different oil to solvent ratios so that the processes may be carried out in the same extraction tower.  The two aromatic extracts in solution in liquid sulphur dioxide may be contacted with a non-aromatic hydrocarbon fraction of different boiling range from the extracts whereby part of the paraffinic content of the extracts is replaced by a paraffinic content of different boiling-point.  Fractionation then yields a product of even higher aromatic content.  A suitable non-aromatic fraction is a de-aromatized heavy kerosine and is used in a proportion of 0.25 to 1.5 : 1 by volume to the combined aromatic extracts solution.  This stage may be carried out at the same temperature as the solvent extractions and in the same tower. Sulphur dioxide and the non-aromatic washing fraction are recycled to the appropriate parts of the extraction tower.  The use of a platinum on alumina catalyst in the reforming stage is referred to.

Abstract: 700,904. Variable-ratio gearing ratchet gearing. BRADBURY, G. H. Jan. 31, 1951 [Oct. 31, 1949; March 24, 1950], Nos. 27814/49 and 7452/50. Classes 80 (2) and 80 (3) A variable-ratio gear comprises a crank element rotatable with a driving shaft and movable eccentrically relatively thereto. and an epicyclic-type differential gear, the sun wheel of which is connected to a driven shaft and the planet wheel's of which are connected by frictional one-way drive devices and links to the crank element whereby rotation of the crank element in an eccentric position tends to oscillate each frictional device thus imparting unidirectional movement to the associated planet wheel and tends also to rotate the planet wheel carrier in the same direction as the driving shaft. As shown in Fig. 3, a plate 12 attached to a driving shaft has radial slots 13 which guide masses 14. A parallelogramic linkage 15 interconnects the masses 14 and, by means of springs 17a, tends to maintain them in the position shown in which a crank pin 17 on one mass is coaxial with the driving shaft. Two pivots of the linkage are guided in radial slots 16 in the plate 12. The pin 17 is connected by links 18 to frictional ratchet devices which on oscillation of the links drive unidirectionally pinions 20, Fig. 2, meshing witih. a gear wheel 21 on an output shaft disposed co-axially with the input shaft. Centrifugal force generated in the masses 14 by rotation of the input shaft moves the pin 17 to an eccentric position thereby oscillating the links 18 and driving the output shaft. It is stated that pinions 20 may planetate against the resistance of a brake or a ratchet device and a positive lock to give a one-to-one drive may be provided. It is further stated that the transmission ratio is automatically adjusted according to engine speed and load torque. In Fig. 5, which illustrates the frictional ratchet device, side plates 37, rotatable about the axis of the wheel 20 and joined by bolts 39 traversing spacers 38, carry levers 41 which are integral' with drive elements 42 about the ends of which the levers pivot. Clearance between the lever 41 and spacer 38 allows the lever to be pivoted by the link 18 into or out of engagement with the smooth peripheral surface of a disc 36 disposed between the plates 37 and fixed to the pinion 20. A spring- 43 tends to maintain the ratchet in its driving position.
