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.

This technology is a waste powder coating recycling process that classifies waste powder coatings by compound and color, performs pretreatment through selection and mixing, removes impurities, and then mixes, melts, and extrudes the material with virgin coating to create chips, which are then pulverized and classified.

By standardizing quality through classification based on compounds and colors, as well as mixing with virgin coatings and remelting, this technology can be applied to the production of recycled powder coatings, allowing waste coatings to be repurposed as a resource.

This technology is a low-temperature packaging box that provides a dual-wall Seokbinggo effect, consisting of an inner box that forms an air gap with an outer box via pillar walls, along with internal intake and exhaust vents.

This technology provides respiratory training content to a user terminal and calculates breathing patterns based on data measured by a respiratory interface. It then adjusts inhalation and exhalation resistance if the patterns deviate from established standards.
Existing cognitive training methods often fail to quantitatively reflect respiratory states and struggle to guide or adjust a user's breathing in real time, limiting the effectiveness of the training.
By adjusting the inhalation and exhalation resistance of the interface when breathing patterns fall outside the target range, this technology guides users toward normal breathing, making it ideal for cognitive training services that aim to improve both respiratory control and cognitive function.
