초록 ▼

A method is provided for controlling the operating temperature of a catalytic reactor using a closed-loop system that provides for varying the reactor input and other operating parameters in order to maintain the operating temperature of the reactor at or near the initial setpoint temperature for operation of the reactor. In one example, maximum and minimum operating temperatures with a catalytic partial oxidation reactor are controlled, as well as maintaining control over the corresponding minimum required ratio of oxygen atoms to carbon atoms, such that the operating temperature within the reactor is maintained below the material limits but above threshold temperatures for coking.

1. A method for controlling the operating temperature of a catalytic partial oxidation reactor in a catalytic partial oxidation process, the method comprising: a) setting an initial setpoint temperature as a maximum operating temperature for operation of the catalytic partial oxidation reactor in the catalytic partial oxidation process, wherein a liquid distillate fuel is contacted with oxygen in the presence of a catalyst within the reactor under reaction conditions sufficient to produce hydrogen and carbon monoxide;b) operating the reactor at the initial setpoint temperature while measuring the operating temperature simultaneously at a plurality of locations within the reactor;c) selecting a maximum observed operating temperature within the reactor from the measurements of step (b);d) selecting a minimum observed operating temperature within the reactor from the measurements of step (b);e) calculating a temperature differential between the maximum observed operating temperature selected in step (c) and the minimum observed operating temperature selected in step (d);f) modifying the initial setpoint temperature based upon the temperature differential by (1) varying a flow of fuel at a fixed air flow, or (2) varying a flow of air at a fixed fuel flow, or (3) alternating flows between (1) and (2); andg) operating the reactor at the modified setpoint temperature until the temperature differential is less than a selected threshold temperature differential. 2. The method of claim 1 wherein the selected threshold temperature differential of step (g) is less than about 350° C. 3. The method of claim 1 wherein the selected threshold temperature differential of step (g) is less than 150° C. 4. The method of claim 1 wherein step (g) further comprises operating the reactor at an increased setpoint temperature until the temperature differential is less than about 150° C. 5. The method of claim 1 wherein step (g) further comprises operating the reactor at an increased setpoint temperature until the temperature differential is less than about 350° C. 6. The method of claim 1 wherein the initial setpoint temperature is set to a maximum operating temperature of between 980° C. and 1020° C. 7. The method of claim 1 wherein the minimum observed operating temperature is greater than the threshold temperature for coking. 8. The method of claim 7 wherein the minimum observed operating temperature is greater than 700° C. 9. The method of claim 1 wherein the catalytic partial oxidation process comprises contacting the liquid distillate fuel with oxygen at an O/C ratio of oxygen atoms in the oxygen to carbon atoms in the fuel as input to the reactor ranging from 1.0:1 to 1.2:1. 10. The method of claim 1 wherein the catalytic partial oxidation process comprises contacting the liquid distillate fuel with oxygen in the presence of a catalyst comprising a wire-mesh substrate coated with a rhodium supported on alumina washcoat.
