Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
115 words
IN A PROCESS FOR PRODUCTIONOF ACETYLENE BY REACTION OF A HYDROCARBON WITH COMMERCIALLY PURE OXYGEN AT TEMPERATURE ABOVE ABOUT 2500* F. IN AN UNOBSTRUCTED REACTION ZONE AND RAPIDLY QUENCHING THE REACTION PRODUCTS AFTER 0.001 TO 0.1 SECOND REACTION TIME, THE IMPROVEMENT FOR MAINTAINING THE REACTION ZONE DIMENSIONALLY STABLE WIHICH COMPRISES: FORMING A MIXTURE OF SAID HYDROCARBON AND OXYGEN, AND DISCHARGING SAID MIXTURE AT A VELOCITY OF 10 TO 30 FEET PER SECOND FROM THE DISCHARGE SIDE OF A POROUS PLATE HAVIN PERMEABILITY OF AT LEAST 80 INTO A REACTION ZONE AUTOGENEOUSLY MAINTAINED AT REACTION TEMPERATURE AND LATERALLY DEFINED BY IMPERFORATE WALLS EXTERNALLY COOLED TO A TEMPERATURE AT LEAST ABOUT 600* F. BELOW SAID REACTION TEMPERATURE.
