Catalyst for Direct Production of Isoparaffine-rich Synthetic Oil and Method for Preparing Catalyst

摘要

A catalyst for producing isoparaffins-rich synthetic oil is a granulated porous composite material comprising a three-dimensional heat-conducting structure of metal aluminum and Raney cobalt, and a binding component comprising an H-form zeolite. The particles of Raney cobalt and zeolite are in mutual direct contact. Fractions of macropores in an open porosity of the catalyst granules and of mesopores of the size of 70-500 Å in an open porosity of the catalyst granules are respectively 55-79% and 7-20%, a fraction of micropores being the rest. A method for preparing the catalyst comprises mixing binding component powders, peptizing the mixture with a nitric acid solution, mixing obtained homogeneous gel with powders of Raney cobalt and metal aluminum and a liquid phase to form a paste, extruding same into granules and calcinating the granules. The catalyst improves reagents mass transfer inside the granules and increases isoparaffine content in the produced oil.
