Abstract A process for synthesizing liquid hydrocarbon includes two-stage air oxidization to obtain nitrogen-containing synthetic gas, cooling via heat exchanger, synthesis reaction in Fischer-Tropsch synthesis reactor in the presence of Co-base alumina catalyst to produce the liquid hydrocarbon whose main component is the paraffine-base hydrocarbons and gas-liquid separation to separate liquid resultant from reaction tail gas. Said catalyst is a Co-base alumina catalyst using La or Ce and Mg or K as assistant. Its advantages are high CO conversion higher than 80%, high yield of liquid hydrocarbon higher than 80%, no pollution of S, N and heavy metals, simple process and less investment.
