Title: Hydroforming of naphthas
Inventor: ROETHELI BRUNO EMIL
IPC: C10G59/04
Filed: 1956-05-22
Abstract: A naphtha is hydroformed and the total effluent from the hydroforming zone is passed without substantial cooling to a dealkylation zone whereby the total normally liquid product so obtained has a distillate volume at 230 DEG  F. greater than that obtainable from the normally liquid hydroformate and at least part of the hydrogen is recycled to the hydroforming zone.  The naphtha may be a virgin naphtha boiling within the range 150-430 DEG  F. or a cracked or Fischer-Tropsch naphtha.  Hydroforming is carried out conventionally using catalysts comprising metals or the oxides or sulphides of metals of Group IV, V, VI and VIII supported on alumina with or without silica in fixed or fluidized beds.  Fluidized processes may be performed at 890-940 DEG  F. and 150-200 p.s.i., fixed bed processes with platinum or palladium catalysts under non-regenerative conditions are operated at 850-960 DEG  F. and 200-700 p.s.i., or under cyclic regenerative conditions at 300-500 p.s.i., and 900-950 DEG  F.  The total effluent including hydrogen is passed without cooling and with heating if necessary to a dealkylation zone which may be a coil heated to 1050-1400 DEG  F. operated at atmospheric pressure to 700 p.s.i.  Space velocities of 0.2 to 5 volumes of hydroformate per volume of coil per hour can be used.  The Provisional Specification refers generally to the thermal treatment of the total effluent from the hydroforming zone including thermal reforming at 250-1000 p.s.i., and 950-1050 DEG  F. and hydrocracking particularly in the presence of a cobalt molybdate catalyst at 925-975 DEG  F. and 220-750 p.s.i.g.

[Also in Group XVII] Apparatus for packaging solids of revolution, e.g. suppositories, having one end heavier than the other, comprises in one form, Fig. 1, a vibrating shoot 2 through which suppositories A are fed in axial alignment from a hopper 1 and from which they are received in succession by a pair of parallel rails 3a, 3b, the spacing between the rails being less than the maximum diameter of a suppository but greater than its diameter in a plane containing its centre of gravity G, see Fig. 2, so that the suppositories are similarly orientated by gravity. The suppositories are caused to move down the rails by an oscillating member 4, which periodically raises their lower ends, until they are arranged fan-wise between the arcuate lower ends of the rails and a retaining member 8, and are then received in succession by recesses 6a in packaging strips 6 which are fed continuously or intermittently over horizontal rails (not shown) in the direction F by a carriage 7. If the strips comprise two or more pairs of recesses arranged transversely, the number of sheets 2 and pairs of rails 3a, 3b is correspondingly increased. The strips 6 may be replaced by a continuous strip which is cut into sections after filling. Alternatively each strip may be supported by a reciprocating carriage, filling taking place during the forward stroke and a retractable member being provided to prevent downward movement of the suppositories during the return stroke. Figs. 3 and 4 (not shown) illustrate a modification for use with " bulletshaped " suppositories whose centre of gravity is nearer their blunt end than their pointed end. In a second form, Fig. 6, the suppositories are fed from a fixed hopper 1 through a partitioned shoot 2 to which are secured arcuate plates 13 corresponding to the rails 3a, 3b. The shoot is resiliently suspended from the hopper and the plates are connected by a bolt 15, resilient brackets 17 and rubber blocks 19 to a fixed frame 18, the assembly being vibrated by a solenoid 21 whose armature is arranged to strike an abutment 20. Suppositories which do not enter the shoot in axial alignment are returned to the hopper by a rotary member 24 carrying flexible vanes 24a, 24b.
