Patent GB-414536-A (GB)
Title: Improvements in or relating to the manufacture of catalysts
IPC: B01J21/00
Filed: 1933-09-18
Abstract: Catalysts of foraminate structure are obtained by treating particles of a material containing catalytic and other constituents with a corroding agent which dissolves out a portion of the non-catalytic constituents, leaving coherent skeletons in which the catalytic substance predominates.  The activity of the product is said to depend on the existence of particles which are partly liberated from the outer and interstitial surfaces of the mass but still retain their relative positions in it.  The time, temperature and concentration conditions of the corrosion treatment should therefore be such as to produce the maximum etching of the surfaces without causing disintegration of the skeleton.  The product may be washed, dried and broken up to about 200 mesh without destroying its foraminate structure.  It may further be reduced to the metallic state.  According to examples: (1) nickel aluminate ground to 200 mesh is leached with 30 per cent sodium hydroxide solution for 1\ba1/2\be hours, most of the alumina being thereby removed.  The product is filtered, dried, crushed and reduced in hydrogen at 450--500 DEG  C.; (2) nickel chromate is similarly treated with a 15 per cent solution of sodium hydroxide; (3) manganese sesquioxide is digested in successive dilute solutions of sulphuric acid of increasing concentration to remove the divalent manganese, leaving a skeleton of manganese dioxide which is filtered, washed, crushed and dried.  Mixtures, e.g. of nickel and copper aluminates, may be treated to obtain mixed catalysts.  The soluble portion of the mass may be produced by chemical treatment of the raw material, e.g. pyrolusite may be reduced with hydrocarbon gas to manganese sesquioxide.  The invention includes the treatment of sulphides and other suitable compounds as well as oxygen compounds and the corroding agent is not necessarily aqueous but may be a gas or an organic solvent.

In an accumulator/adder in which binarycoded (1-2-4-8) decimal digits are added or subtracted in series by bit, in series by digit, a filler digit is always added to one of the digits by 6-adder 480 before it is entered in the main adder 481 if the operation is addition, and, if there is no carry from the operation in adder 481, a further digit is added to the sum output by 10-adder 485 to counteract the effect of the filler digit. Inputs from circuits 490 and 494 or 495 are applied both to the main adder 481 and a carry determining circuit 482. If a carry occurs the ten generator 487 is inhibited and the output of adder 481 passes unchanged through 10-adder 485 from where it may be recirculated to circuits 490, 491, 494 or 495. On subtraction the 6-adder 480 is inhibited and the digit from input circuits 490 or 491 is complemented. A 1 is always added to the main adder from circuit 482 and if there is no carry in circuit 482 the ten generator operates the 10-adder 485. The answer may be complemented by passing it through circuit 492 on a second pass through the accumulator.
