Abstract
This invention relates to the conversion by way of decomposing a solid carbonaceous matter to acetylene. Specifically, the invention teaches selecting the operating conditions which will produce high yield at low cost. Specific values of heat and enthalpy for the carbonaceous matter and the gas are proposed in combination with specific particle sizes and reaction time. All of the foregoing contribute to producing acetylene at a commercially competitive cost.

A method of producing acetylene from coal by decomposing coal in hydrogen:
- supplying coal particles and hydrogen at a predetermined controlled rate to a reaction zone;
- heating said coal and hydrogen so that the decomposition reaction takes place under conditions embraced by the area defined by the x, y coordinates (1.0, 2.5) (2.0, 2.5) (5.0, 1.5) (5.0, 0.6) (2.0, 0.6) (1.0, 1.25) where x coordinate is the specific gas enthalpy in Kw/SCFM H.sub.2 and the y coordinate is the specific solid enthalpy in Kw/lb. carbon per Hr to produce acetylene;
- and
- removing said acetylene from the reaction zone to prevent it from decomposing.
