Title: Improvements in the catalytic dehydrogenation of hydrocarbons
IPC: C07C5/48
Filed: 1952-04-30
Abstract: Hydrocarbons are dehydrogenated in the gaseous or vaporous phase at elevated temperature in the presence of a finely divided dehydrogenation catalyst which is brought into a turbulent state by a mixture consisting of gaseous or vaporous hydrocarbons and steam blown into the reaction chamber, by a process wherein the hydrogen evolved by the dehydrogenation of the hydrocarbons is converted into water by equivalent amounts of oxygen which are introduced separately into the reaction chamber after the dehydrogenation has been initiated.  The heat of combustion of hydrogen is sufficient to supply the necessary dehydrogenation heat and further external heating is not required once the process is initiated.  Excess heat may be removed by introducing the hydrocarbons to be dehydrogenated partly or wholly in the liquid phase or by spraying in water.  The process is illustrated with reference to a cylindrical reaction vessel having a conical bottom which is filled to one quarter or fifth with a finely powdered dehydrogenation catalyst with a grain size of 20 microns to 2 mm.  The catalyst is brought into a turbulent state by blowing in steam or nitrogen at the bottom and is heated to reaction temperature by an electrical heating jacket or directly with fuel gas.  The hydrocarbon is blown in as a vapour, if desired with steam, and once the reaction is initiated, oxygen or air is blown in by means of annularly arranged nozzles and the heating is discontinued.  The product vapours pass through a separator, a filter and a heat exchanger and then into a dephlegmator in which the reaction product and water are precipitated.  The conversion of ethylbenzene to styrene at a temperature of 580 DEG  C. is described by way of example.

Abstract: 1,140,489. Moulding refractory grids. R. PYZEL. 8 March, 1967 [12 July, 1966], No. 10837/67. Heading B5A. [Also in Division F4] In a fluidized solids reactor wherein air or gas under pressure is passed from a supply chamber through holes in a refractory grid to fluidize material in a treatment chamber thereabove wherein it is subjected to high temperature, the refractory grid is cast into position over the supply chamber, from alumina with an alumina cement binding agent, into a mould form comprising sections defined by removable partitions whereby adjacent sections are sequentially cast and hardened. The supply chamber shell (60) (Fig. 2, not shown) lined with cast insulation (70) and welded to a vertical circular grid retaining wall (40) and provided with a horizontal flange (61) for connection to the treatment chamber, is positioned beneath the treatment chamber and a steel plate bottom form (30, 31) is positioned thereon. The bottom form (30, 31) comprises an upwardly directed spherical segment provided with a plurality of core retaining holes (32), and an outer form ring 10 is positioned forming an upward extension of the wall (40). An inner form ring 20 is then positioned within ring 10 together with radial form partitions 1, defining alternate sections A, B. Tapered wooden or meltable material tubular cores 33, for forming the supply holes through the grid, are removably secured e.g. by screws, to the holes in the bottom form with the wider ends adjacent thereto; the cores 33 project above the surface of the cast grid where they are connected by strips 35 defining parallel lanes along which the surface is trowelled and along which electrically or pneumatically actuated vibrators traverse through the cast material. Other cores 33 (not shown) similarly may form material feed and fuel line openings through the grid. The sections A are firstly cast and hardened for eight to twelve hours followed, after removal of the radial partitions 1, by sections B; keying between adjacent sections being ensured by interfitting ridges and grooves formed by horizontal strips 5 secured to the partitions. The inner form ring 20 is then removed and grid sections A<SP>1</SP>, B<SP>1</SP> and C, defined by removable form partitions 2, 3, are similarly sequentially cast. The grid holes containing the cores 33 are then countersunk and the bottom form member dismantled or disintegrated with heat from the supply chamber. The grid is heat cured by heat from the supply chamber passing through the cores 33, which are thereby burnt or melted, and the supply chamber assembly is then jacked into engagement with and connected to the treatment chamber.

Filed: 1924-05-05
Abstract: 238,275. Ionides, A. C., and Gordon, J. W. May 5, 1924. Levels; sextants; theodolites. - Reflector systems comprising two facing mirrors at an inclination to one another in combination with an additional mirror, which may be a single plane mirror or two plane mirrors at right-angles with fixed or adjustable angular relation to the first mentioned two mirrors, present two separate images to the eye of an observer and are utilized for reading angular magnitudes and are applied to several optical instruments, e.g. levels, sextants, &c. In one form, Figs. 1 and 3, two inclined mirrors a are combined with a plane mirror b, which lies at right-angles to the axis of symmetry 1 - - 1 of the mirrors a. This form will reflect into the eye of an observer, two views of a distant object one laterally reversed with respect to the other, the views only coinciding along the principal axis, which serves as a fiducial line of any instrument to which the system is applied. The plane mirror b may occupy a central position as shown in Fig. 2, separating the upper and lower portions of the view observed in the inclined mirrors a. In a modification one of the inclined mirrors a may be replaced by two mirrors at 45‹ to the horizontal and to the plane mirror b. As applied to a pendulum level the system is mounted as shown above the pivot of the pendulum j which is supported on gimbal rings, and damped by liquid in a container k<2>. A rod l<4> is provided to lift the pendulum off its supports and simultaneously to close the container k<2>. The reflecting system is arranged to show the level by a horizontal fiduciary line given by coincidence of two views, one laterally inverted. A surveyor's level is shown in Fig. 20 in which the reflecting system p<4> is mounted beneath a telescope p<5> upon the ordinary stand. As applied to a sextant, Figs. 13 and 14, the facing mirrors a<3>, a<4> are parallel to one another and to the zero position of the adjustable mirror b<3>. The mirror a<3> covers one half of the object glass and the index glass b<3> is of such a height that the reflected rays are received by the other half of the object glass of the telescope a. The mechanism for adjusting the glass b<3> is on the hinder face of the instrument, rough adjustment being effected by the wheel n<1> and fine adjustment by the wheel n<7>. In the modified square shown in Figs. 18 and 19, the plane mirror b, Fig. 2, is replaced by two mirrors b<5>, b<6> at right-angles, placed symmetrically.
