Title: Improved process for the decomposition under the action of heat of a mixture of methane or other hydrocarbons and water vapour
IPC: C01B3/46
Filed: 1929-09-03
Abstract: <PICT:0343172/III/1> <PICT:0343172/III/2> In the non-catalytic thermal decomposition of a mixture of methane or other gaseous hydrocarbons and water vapour, the heat is supplied by the combustion of gases in the reaction chamber during one period, the air for combustion being preheated but not the gases for combustion, and the preheated reaction gases being passed in an opposite direction through the heated reaction chamber during the next period.  In one modification, Fig. 1, during one period the air for the combustion entering a heat exchanger A at 2, passes into a reaction chamber C, into which a portion of the hydrocarbon gases are directly introduced through a three-way cock 3, the burnt gases passing through the other compartment of the heat exchanger A and leaving at 1.  During the next period the supply of air is cut off and a mixture of hydrocarbon gas and steam passes into a heat exchanger B via the three-way cock 3 and, after traversing the reaction chamber 3, passes out at 4.  In another modification, Fig. 2, the air for combustion entering a regenerator B at D, is joined by directly introduced hydrocarbons in a reaction chamber or conduit C, the burnt gases traversing a regenerator A and escaping at E.  During the next period, the supply of air and directly introduced gas is cut off and a mixture of hydrocarbon gas and steam passes via a three-way cock into the lower part of the regenerator A, through the reaction chamber or conduit C, and out through the lower part of the regenerator B.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also modifications, forming the subject-matter of the divided Specification 341,393, in which the combustion gases and reaction gases simultaneously traverse separate compartments of a heat exchanger, and in addition, a modification in which the regenerator B, Fig. 2, is replaced by a boiler, and another modification in which each compartment of the heat exchangers A, B, Fig. 1, is replaced by a regenerator, valves being provided to reverse periodically the direction of both the combustion air and the reaction gases through the apparatus, the process thus comprising four periods of operation. This subject-matter does not appear in the Specification as accepted.
