A mixture of natural gas and air is converted to a C 5-C19 diesel fuel-grade liquid hydrocarbon. The natural gas and air mixture is supplied to the input of a catalytic partial oxidation reactor. The carbon-containing gas output of the catalytic partial oxidation reactor is connected as an input to a first Fischer-Tropsch reactor, to thereby form a first diesel fuel grade C5-C19 liquid hydrocarbon output. A carbon-containing gas output of the first Fischer-Tropsch reactor is connected to the input of a second Fischer-Tropsch reactor, to thereby form a second diesel fuel grade C 5-C19 liquid hydrocarbon output. The catalytic partial oxidation reactor contains a platinum group catalyst, a promoted platinum group catalyst, a rhodium catalyst, or a platinum promoted rhodium catalyst. Each of the Fischer-Tropsch reactors contain a catalyst that is made up of from about 3 to about 60 parts-by-weight cobalt and from about 0.1 to about 100 parts-by-weight of at least one metal selected from a group consisting of cerium, lanthanum and ruthenium per 100 parts-by-weight of a support selected from a group consisting of silica, alumina and combinations of silica and alumina, and more preferably a catalyst that is made up of about 20 percent by weight cobalt, about 0.1 percent by weight ruthenium, about 0.1 percent by weight platinum, the remainder being an alumina support.
