Catalytic reactor for the conversion of carbon dioxide and hydrogen to syngas

A catalytic reactor for the production of syngas from mixtures of hydrogen and carbon dioxide to syngas comprising:

• a. an inlet nozzle;
• b. an outer shell of metal with a thickness between ¼ inches and 10 inches;
• c. a refractory layer that has a thickness of between 6 and 18 inches where the refractory layer comprises an insulating material:
• d. an inner sleeve that has a surface that is made from at least one high-temperature alloy where the high temperature alloy comprises nickel and chromium where the nickel is between 29 and 75 wt % of the alloy and the chromium is between 13 and 32 wt % of the alloy;
• e. a catalyst bed capable of converting mixtures of carbon dioxide and hydrogen to carbon monoxide;
• and steam, where the catalyst bed comprises multiple catalyst sections separated by at least one high temperature alloy sheath and wherein the number of catalyst sections is from 2 to 100, and where the catalyst bed is penetrated by resistive heating elements:
• f. one or more resistive electrical heating elements;
• g. and an outlet nozzle.
