Title: Method and device for electrochemical catalyst oxidation of sulphur dioxide
Inventor: BUDEVSKI EVGENI B
IPC: C01B17/775
Filed: 1987-08-06
Abstract: The electrochemical, catalytic oxidation of sulphur dioxide to sulphuric acid is carried out by bringing a gas mixture having a sulphur dioxide content of 0.01 to 50% by volume simultaneously into contact with oxygen and an electrolyte - water or a solution of sulphuric acid - over a catalyst which is activated carbon or activated carbon provided with metal complexes of organic compounds (porphyrins, anulenes, phthalocyanines, and the like) or products of their thermal decomposition, or activated carbon provided with platinum, palladium or rhodium in amounts of 0.1 to 1% by weight and has been made hydrophobic by means of hydrophobic polymer compounds (polytetrafluoroethylene, polyisobutylene, polyethylene, and the like) or by means of a mixture of a few of these compounds at a ratio of catalyst : hydrophobisizing agent of 25:1 to 1:4 at a reaction temperature of 10 to 80 DEG C. In the apparatus according to the invention, the hydrophobisized catalyst is applied as a porous catalytic layer to sheets made of a hydrophilic fibre base or a porous base, which leads to formation of a three dimensional matrix for holding back and draining the acid. These catalytic sheets are arranged such that gas ducts are formed between them whose constant volume is secured by means of spacing elements. The upper ends of the catalytic sheets are mounted in the distributing tank for the acid feed. The electrochemical, catalytic oxidation of sulphur dioxide to sulphuric acid with simultaneous participation of oxygen and water takes place in the porous layers of the hydrophobisized catalyst which forms a spacing layer between liquid phase and gas phase. <IMAGE>

Patent CA-2000001-A1 (CA)
IPC: G01N27/72
Filed: 1989-10-02
Abstract: Oxygen sensing apparatus and methods utilize a sensing cell including two pairs of electrically heated thermistors and a source of an inhomogeneous magnetic field.  One thermistor of each pair is positioned inside the magnetic field, and the second thermistor of each pair is positioned adjacent to the respective first thermistor of each pair, substantially outside the magnetic field.  When oxygen is present in the sensing cell, the thermistors inside the magnetic field generate a gas flow in the direction of the adjacent thermistors of each pair positioned outside the magnetic field, thus tending to reduce the temperature of the thermistors inside the field and increase the temperature of the thermistors outside the field.  The thermistors are connected in a measuring bridge circuit including elements for maintaining the temperature of the thermistors at a substantially constant level, thereby providing a signal that can be used to compensate for changes in the thermal characteristics of the background gases.
