Abstract: The invention provides a method for mixing two or more gaseous or liquid streams, where the gaseous streams are combined in an inlet chamber and thereafter repeatedly accelerated and decelerated in one or more of stages, and a value of a maximum linear velocity of the accelerated combined gaseous stream is maintained in each step within a range of mass flow rates of the gaseous streams. The invention also provides apparatus for mixing two or more gaseous or liquid streams, one embodiment comprises a body with a seat; a spindle with a plug, which is installed in the seat and the seat and the plug have a plurality of conical surfaces forming the same plurality of conical annuli. The spindle is able to move the plug in an axial direction in the seat during the mixing. Another embodiment comprises a body, a spindle with a tube plug. A cage and annular mixing elements surround the tube plug.

Abstract: A method for measurement of high temperatures of a process stream by means of a thermocouple arranged in a thermowell. The thermowell is at least partly covered by a layer of a catalytic material which is active in at least one endothermic reaction. The thermowell is installed in a reactor by inserting the thermowell through a hole penetrating the reactor wall so that the tip of the thermowell is in contact with the process stream. The invention is typically used where the reaction is a reforming reaction and the reactor is an autothermal reformer fed with a hydrocarbon stream and an oxygen containing stream.

Abstract: A reactor for processes involving reactions of gasses at high temperatures comprising a gas impermeable basket suitable for operation at elevated temperatures surrounded by a layer of insulation material, the insulation material being surrounded by a reactor shell suitable for operation at elevated pressures. The basket comprises an inlet channel and a wall surrounding a fixed catalyst bed, and the inlet channel is connected to the reactor shell forming a gas leak tight transfer for a feed gas. An electric heater can be installed on the outer surface of the wall around the inlet layer of the catalyst bed and the installed catalyst is in form of particles or a monolith. The reactor is particularly useful in catalytic partial oxidation of hydrocarbons.

Abstract: A process for the preparation of hydrogen and carbon monoxide rich gas by steam reforming of a hydrocarbon feedstock in the presence of a steam reforming catalyst disposed in the pores of a porous supporting structure aligned and adhered along the wall of a reforming reactor.

Abstract: Method for the depression of soot formation during combustion of fuel rich hydrocarbons in a combustion chamber by applying an electrostatic field in the combustion chamber by means of one or more electrodes at least a portion of the electrodes extend into the chamber, wherein the portion of the electrodes extending into the chamber comprises porous ceramic material.

Abstract: The invention relates to a process for the production of electricity in a fuel cell system by steam reforming a carbonaceous fuel to form fuel cell reactant gas and recycling recovered reactants from the anode exhaust gas to the anode inlet. There is obtained an increase of the electricity production of 20-30% if prior to the recovery and recycling the anode exhaust gas is passed over a steam reforming catalyst by which lower hydrocarbons in said exhaust gas is converted to reactants for use in the fuel. The carbonaceous fuel may for instance be natural gas or methane. A fuel cell system for use in the process comprises supply means (2,10) for carbonaceous fuel; an inlet reformer unit (6) for producing reactant gas for the fuel cell (4); an outlet reforming unit (12) for converting hydrocarbon-containing anode exhaust gas to anode reactant gas; and means (18,90) for recovering the reactant gas and recycling recovered anode reactant gas.
