Cobalt-Iron Hybrid Catalyst Having Ordered Mesoporous Channels As a Main Framework for Fischer-Tropsch Synthesis, a Method for Preparing the Same, and a Method for Preparing Hydrocarbons

High temperature stable mesoporous cobalt-iron hybrid catalyst

This technology relates to a cobalt-iron hybrid catalyst for Fischer-Tropsch synthesis reaction, a method for producing the same, and a method for producing hydrocarbons using the same. A cobalt-iron hybrid catalyst for the Fischer-Tropsch synthesis reaction having a regular mesoporous main skeleton in which cobalt oxide and iron oxide are uniformly mixed, a method for producing the same using a hard casting technique, and a method for producing hydrocarbons using the same. This is about the method of producing hydrocarbons.

The existing Fischer-Tropsch catalyst had difficulties in efficient hydrocarbon synthesis due to problems such as low activity and structural instability. This technology overcomes these limitations by developing a cobalt-iron hybrid catalyst with a regular mesoporous main skeleton.

This catalyst has a three-dimensional structure in which cobalt oxide and iron oxide are uniformly mixed, and is manufactured using a hard casting technique, maintaining high activity and excellent structural stability even at high temperatures and harsh reaction conditions, enabling a stable Fischer-Tropsch reaction without a separate cocatalyst. This allows selective, high-yield production of C2-C4 light hydrocarbons and C5+ heavy distillate hydrocarbons from syngas.

Key Features:

• Manufacturing a hybrid catalyst with a three-dimensional porous structure in which cobalt oxide and iron oxide are uniformly mixed through a hard templating method using mesoporous silica as a 'frame'
• The skeleton of the catalyst itself is made of active materials (Co, Fe), so it has more reaction active sites than existing support catalysts
• Cobalt-iron mixed oxide (CoFe2O4, etc.) is a structure enhancer It maintains the porous structure stably without collapsing even under high-temperature hydrogenation reaction conditions.
