1. A process for the conversion of a feed gas comprising carbon dioxide and hydrogen to a product gas comprising carbon monoxide and water where:
a. the feed gas is heated to an inlet temperature greater than 1,400° F. in a preheater outside the main reactor vessel to produce a heated feed gas, wherein the preheater is an electrically heated radiant furnace;
b. the radiant furnace uses electricity to generate heat and produce the heated feed gas, and wherein the radiant furnace uses less than 0.5 MWH electricity/metric ton of CO2;
c. the heated feed gas is sent to a main reactor vessel, wherein the main reactor vessel has an inlet temperature and an outlet temperature, and wherein the main reactor vessel outlet temperature is 100 to 200° F. less than the main reactor vessel inlet temperature, and wherein there is a mass flow rate of reactants in the main reactor vessel, and wherein the mass flow rate is between 1,000 and 60,000−1;
d. the main reactor vessel is maintained at or near isothermal conditions;
e. the main reactor vessel contains catalyst that converts the heated gas to the product gas.
