In modifications there may be a streamline body 31 in the chamber 29 to promote laminar flow; the body 31 may have a through bore (42, Figs. 2 and 3, not shown); there may be an extended jet nozzle (28', 28" Figs. 4 and 5, not shown) and a shortened acceleration chamber (29', 29") associated with a chamber (45, 45') of larger diameter between the acceleration chamber and the apertured disc, the apertures (47') being optionally convergent. The acceleration chamber and injector tube may be formed in replaceable inserts 26, 13 as shown of synthetic material and the suction passage 19 includes annular grooves 18, 20. In another embodiment, Fig. 6, the injector tube may have convergent inlet portions 68, 69 and a divergent outlet portion 15' and the jet nozzle 54' may be formed in a conical projection 57 extending to the inlet of the injector tube. Preferably the diameter of the bores in the disc 39 is smaller than their length; the free jet path is 20-25 mm long; the inlet of chamber 33 is at least twice the nozzle 28 diameter and the chamber is at least 15 mm long; and the inlet portion 68 is at least 20 mm long. The angles of divergence of chamber 29 and body 31 are such that the cross-section of the flow passage decreases towards the nozzle. The apparatus may supply a shower head (1, 2) the pipe (4) to which is at least twice the diameter of bore 15.

Title: Improvements in the manufacture and production of valuable hydrocarbons from varieties of coal, tars, mineral oils and the like
IPC: C10G1/06
Filed: 1930-02-26
Abstract: <PICT:0348252/III/1> Heat is supplied during a destructive hydrogenation process by adding to the reaction mixture, the treatment of which has already started, oxygen-containing compounds of carbon which under the working conditions are reduced to hydrocarbons with the evolution of heat.  Suitable compounds are oxides of carbon or phenols.  The initial materials are preferably preheated to 350-380 DEG  C. and the oxygen-containing compounds of carbon are then added at one or more points in the reaction system. Strongly hydrogenating catalysts such as molybdenum and tungsten may be used.  A petroleum fraction boiling at 200-350 DEG  C. is forced by a pump H through a heat exchanger K.  Hydrogen is added through a pipe J. The mixture passing out at M is heated in a coil O to 460 DEG C. and passed in a vaporous state into a reaction vessel A containing a catalyst C of zinc and molybdenum.  From this vessel, the mixture passes on to enter a second vessel A<1> at B<1>; to prevent a fall in temperature, carbon dioxide in the proportion of ,05 per cent is introduced at E.  96 per cent of the carbon dioxide is reduced to methane.  The products are recovered in the usual manner.  In place of carbon dioxide, a brown coal tar fraction containing 28 per cent of phenols may be used. Specification 257,256 and 331,548, [both in Class 32, Distilling &c.], is referred to.
