Abstract
The invention relates to a catalyst for producing an isoparaffins-rich synthetic oil from CO and H2 and to a method for preparing this catalyst. An object of the present invention is to improve mass transfer of reagents inside of catalyst granules and increase content of isoparaffins in the produced oil. The catalyst is granulated porous composite material comprising a three-dimensional heat-conducting structure of metal aluminum and Raney cobalt, and a binding component comprising a H-form zeolite. The particles of Raney cobalt are in direct contact with the particles of the zeolite. The method for preparing the catalyst comprises mixing of binding component powders, peptizing the obtained mixture with a solution of nitric acid to obtain the binding component in the form of a homogeneous gel, mixing of the homogeneous gel with a fine powder of Raney cobalt, powder of metal aluminum and a liquid phase to form a homogeneous paste, extrusion of the prepared paste to form granules and calcination of the obtained granules. The H-form zeolite is used as one of the binding component powders.
