Title: Catalytic dehydrogenation method
IPC: C07C5/333
Filed: 1956-10-25
Abstract: In a process for the production of aliphatic conjugated dienes by the dehydrogenation of the corresponding olefine over a granular calcium nickel phosphate catalyst comprising the alternate steps of (1) passing a vapour mixture of steam and the olefine over the catalyst; and (2) passing a mixture comprising steam and elemental oxygen over the catalyst to regenerate it, the occurrence of a difference in temperature of more than 10 DEG  C. between the highest temperature reached in the catalyst bed in the second step and the maximum temperature of the bed in the first step is prevented by controlling the ratio of the amount of oxygen to the amount of olefine fed in the respective steps, this ratio being increased to increase the heat generated in the bed in the second step or vice versa to bring the temperature difference within the necessary range.  The oxygen-olefine ratio may be controlled by changing the relative feed rates or the relative durations of the two steps but preferably by varying the proportion of oxygen or air in the mixture used in the regeneration, this may be accomplished manually or automatically. The proportion of oxygen in the regenerating gas is not changed during the regenerating step but is varied between one step and the next. The conditions used are otherwise conventional and the process may be applied to the formation of butadiene-1,3; 2,3-dimethylbutadiene-1,3; isoprene or piperylene from respectively either or both n-butenes; 2,3-dimethylbutene-1; isoamylene or pentene-1.ALSO:In a process for the dehydrogenation of olefines to diolefines (see Group IV (b)) over a granular calcium nickel phosphate catalyst comprising the alternate steps of (1) passing a vapour mixture of steam and the olefine over the catalyst; and (2) passing a mixture comprising steam and elemental oxygen over the catalyst to regenerate it, the occurrence of a difference in temperature of more than 10 DEG  C. between the highest temperature reached in the catalyst bed in the second step and the maximum temperature of the bed in the first step is prevented by controlling the ratio of the amount of oxygen to the amount of olefine fed in the respective steps, this ratio being increased to increase the heat generated in the bed in the second step or vice versa to bring the temperature difference within the above range. The oxygen-olefine ratio may be controlled by changing the relative feed rates or the relative durations of the two steps but preferably by varying the proportion of oxygen or air in the mixture used in the regeneration, this being accomplished manually or automatically. Normally the proportion of oxygen in the regenerating gas is not changed during a regeneration step but is varied when necessary between one regeneration and the next.

Title: Improvements in or relating to fish netting
Inventor: JOHNSON ROLAND
IPC: D06M23/06
Filed: 1958-10-14
Abstract: Fish netting comprising essentially uncoated twine of synthetic filament material knotted with tight single knots, the knots being substantially evenly spaced apart and intervened by precise lengths of twine, is given reduced slip-mesh characteristics by impregnation with a 1 to 40% by weight solution of rosin and allowing the rosin to set at a temperature having no effect on the twine per se, to leave in the netting 1 to 40% of rosin.  The netting may be impregnated in its stretched or unstretched form, before the knots have loosened, or it may be stretched after knotting to tighten any loose knots and then dipped in the rosin solution.  The rosin may be any of the gum or wood rosins, preferably having a saponification number of 145 to 270, or a natural rosin which has been chemically modified by, for example, the addition of glycerine or treatment with lime.  It may be applied from solution in water or an alcohol, e.g. methyl, ethyl or isopropyl alcohol.  When the solvent contains alcohol from 0,5 to 3% by weight of an alcohol-soluble synthetic resin, e.g. a polyamide, an acrylic resin, a polyester, a vinyl copolymer, a polyvinyl acetal, particularly polyvinyl butyral, or cellulose acetate, may be added to the solution.  When an aqueous solution is used a dissolving agent such as triethanolamine with sodium hydroxide may be added to keep the rosin in solution, and an antigelling agent, e.g. furfural, may also be added.  The netting may be impregnated at room temperature for about 20 seconds and then dried at room temperature.  Specified synthetic filaments are partially acetylated cellulose derivatives, polyamides, polyesters and "Orlon" (Registered Trade Mark). Specification 748,760 and U.S.A.  Specifications 2,590,586 and 2,653,372 are referred to.

Filed: 1957-10-30
Abstract: The per cent loss of fluorine from a Pt-Al2O3 reforming catalyst is calculated thus: 2.22 x square root of (average per cent molar water content of recycle gas x hours on stream); fluorine or a fluorine compound (preferably organic, e.g. (i) t-butyl fluoride or (ii) benzotrifluoride) is then added, possibly in excess of that lost, to the reactor.  The organic fluoride is added dissolved in a liquid hydrocarbon fraction boiling within the gasoline or naphtha range; particularly, the said fraction is not preheated, is under an elevated pressure of hydrogen, and the reactor is at 800-900 DEG  F. Chlorine may also be introduced, using e.g. a mixture of (i) with t-butyl chloride, or CH2Cl2F2 alone.  It is preferred that the addition of fluorine and possibly also chlorine is carried out in conjunction with (i.e. before or after) conventional regeneration.
