Abstract: A catalytic testing device comprising a reaction block comprising a set of reaction chambers, each chamber comprising a fluid inlet and outlet connected to an outgoing fluid duct connected to analysis means, fluid feed means capable of performing regulated dosing of flows of the fluid at the required pressure independently in each of the reaction chambers, automatic and dynamic pressure control means, capable of performing pressure regulation in each reaction chamber, which comprise a non-return valve in the outgoing fluid duct between the outlets of the reaction chambers and a common regulating tank that receives the outgoing fluid from the chambers, a pressure sensor provided in a first outlet duct and an automatic needle valve provided in a second outlet duct from the tank.

Abstract: A cathode for high-temperature fuel cell, comprising a layer of porous particles applied on a sintered electrolyte, the layer having a surface area of 15 to 900 m2 per gram and the average size of the porous particles do not exceed 30 nm and a method for preparing the same.

Abstract: The invention relates to a catalytic method for the transalkylation/dealkylation of organic compounds, consisting in bringing a supply comprising organic compounds into contact with a catalyst containing a first zeolitic component that is selected from among: a) one or more zeolites having crystalline structure ITQ-13; b) one or more zeolites having crystalline structure ITQ-13, which are modified either by means of selectivation or with the incorporation of one or more metals, or both; and c) a mixture of a) and b). The invention also relates to a catalyst comprising one or more modified zeolites having crystalline structure ITQ-13.
