PROCESS FOR THE CONVERSON OF NATURAL GAS INTO MIDDLE DISTILLATES |

| Abstract |
An improved process is disclosed for the conversion of natural gas into middle distillates. In the process natural gas is converted into synthesis gas or syngas consisting essentially of carbonmonoxide and hydrogen. The syngas is contacted with a series of three catalyst beds comprising of an admixture of oxides of copper zinc and aluminium in the first bed an oxide of aluminium in the second bed and silicate salt of a rare earth metal in the third bed. From the aqueous phase the olefinic hydrocarbons are separated and then converted into oligomers boiling in the middle distillates range by contacting with solid oligomerization catalyst. The oligiomers in admixture with hydrogen are then converted into middle distillates by contacting the admixture with a hydrogenation catalyst. The middle distillates are well known for their varied applications as fuel and illuminators. |
