Patent ID: 7419830

Claim:
An automatic catalytic testing device comprising at least one reaction block ( 5 ) which comprises a set of reaction chambers ( 4 ) capable of housing solid materials in their interior and each chamber ( 4 ) comprising a fluid inlet, and an outlet connected to an outgoing fluid duct ( 24 ) which communicates with analysis means ( 8 ) through duct ( 22 ), means of fluid feed ( 1 , 10 , 11 ) capable of performing regulated dosing of flows of at least one fluid with exactitude at a required pressure independently in each of the reaction chambers ( 4 ), said required pressure being common to each of the reaction chambers, automatic and dynamic pressure control means, capable of performing pressure regulation in each reaction chamber in conjunction with other reaction chambers, the pressure control means comprising at least a first non-return valve ( 23 ) provided in the outgoing fluid duct ( 24 ) between the outlet for each reaction chamber and a common damping tank ( 6 ) that receives the outgoing fluid from each reaction chamber ( 4 ), a pressure sensor ( 3 b ) provided in a first outlet duct ( 25 ) and an automatic needle valve ( 20 ) provided in a second outlet duct, and sample taking devices ( 13 ) for sample taking, in order to permit the regulated circulation of fluid from the outlet of any reaction chamber as far as the analysis means.
