Abstract: The present invention provides a process for the manufacture of acetylene and other higher hydrocarbons from methane feed using a reverse-flow reactor system, wherein the reactor system includes (i) a first reactor and (ii) a second reactor, the first and second reactors oriented in a series relationship with respect to each other, the process comprising supplying each of first and second reactant through separate channels in the first reactor bed of a reverse-flow reactor such that both of the first and second reactants serve to quench the first reactor bed, without the first and second reactants substantially reacting with each other until reaching the core of the reactor system.

Abstract: A method and apparatus for generating acetylene gas by reacting water and calcium carbide wherein a tank containing water is pressurized by a pump in a manner feeding the water to another vessel wherein it reacts with particulate calcium carbide to generate acetylene gas. A portion of the acetylene gas is returned through a pressure regulator to the water tank in a manner maintaining regulated system operating pressure on the water to sustain the reaction without overproduction of the gas. The apparatus can be located in a vehicle for on board generation of acetylene gas as fuel for the internal combustion engine thereof.
