Claim 1
Independent Claim
153 words
IN A PROCESS FOR THE SYNTHESIS OF HYDROCARBONS BY THE CATALYTIC CONVERSION OF CARBON MONOXIDE-HYDROGEN MIXTURES, THE IMPROVEMENT WHICH COMPRISES CONTACTING SAID MIXTURES IN A SYNTHESIS REACTION ZONE WITH AN IRON CATALYST AT A TEMPERATURE WITHIN THE RANGE OF 220 TO 280*C. AND AT A PRESSURE WITHIN THE RANGE OF 185 TO 440 POUNDS PER SQUARE INCH GAUGE, MAINTAINING A BODY OF LIQUID COOLANT IN SAID SYNTHESIS REACTION ZONE, INTRODUCING SAID COOLANT TO SAID REACTION ZONE AT THE BOILING POINT OF SAID COOLANT AND AT THE SYNTHESIS REACTION TEMPERATURE WITHIN THE RANGE OF 220 TO 280*C., COUNTERCURRENTLY TO THE FLOW OF SAID GASEOUS MIXTURES WITH COOLANT FLOWING DOWNWARDLY BY GRAVITY OVER SAID IRON CATALYST WITHOUT ESTABLISHING A LIQUID LEVEL IN SAID REACTION ZONE, AND REGULATING THE PRESSURE IN SAID REACTION ZONE WITHIN THE RANGE OF 185 TO 440 POUNDS PER SQUARE INCH GAUGE SO AS TO MAINTAIN SAID COOLANT AT ITS BOILING POINT.
