Title: Improvements in and relating to the production of unsaturated hydrocarbons
IPC: E04C3/22
Filed: 1956-06-20
Abstract: <PICT:0821109/IV (a)/1> A process for the production of acetylene by the partial oxidation of a substantially saturated hydrocarbon comprises mixing streams of gaseous hydrocarbon preheated to 400-900 DEG  C. at a velocity greater than Mach number 0.5, igniting the mixture while injecting it into a reaction zone at a velocity greater than the flame velocity and quenching the products so that the total p  reaction time is between 1 and 4 milliseconds.  The reactants are preferably mixed at about sonic velocity and the reaction pressure is between 16 and 20 p.s.i.a.  Natural gas is a suitable hydrocarbon, or a hydrocarbon containing 1 to 4 carbon atoms, in which case the volume ratio of hydrocarbon to oxidant is between 0.7 to 1 and 2 to 1.  In the apparatus of Fig. 1, an oxidant such as oxygen is fed through inlet 16, tube 36, and ports 42 which terminate perpendicular to the conical end of the member 32.  The hydrocarbon is fed by conduit 24, tube 44 and the conical annular passage 46 where it is mixed with the oxidant.  In order to obtain velocities at or near sonic, a pressure ratio across the ports 42 and the passage 46 should be about 2:1.  The gases pass down the mixer throat 50 and into the reaction zone 52, at the entrance to which is a suitable flame holder, in this case a stagnation area at the shoulder created by the sharply enlarged entry into the reaction zone which is equipped with a ceramic wall 51 which assists in holding the flame.  Quenching means, not shown, are arranged to quench the products within 4 milli-seconds of the initiation of combustion.  Internal cooling passages are provided through which a coolant such as water may be passed.
