In the present disclosure, a dehydrogenation catalyst in which cobalt in the form of single atom is supported on an inorganic oxide (specifically, silica) support in which an alkali metal in the form of single atom is fixed by alkali metal pretreatment and a method for producing the same, and a method for producing olefins by dehydrogenating corresponding paraffins, specifically light paraffins in the presence of the dehydrogenation catalyst are described.

Cobalt-based single-atom dehydrogenation catalysts and method for producing corresponding olefins from paraffins using the same

Provided is a dehydrogenation catalyst having single-atom cobalt loaded onto a support including a zirconia core surface-modified with silica, a method for producing the dehydrogenation catalyst, and a method for producing corresponding olefin through dehydrogenation of paraffin, particularly light paraffin, in the presence of the dehydrogenation catalyst.

Cobalt-based single-atom dehydrogenation catalysts having high selectivity and regenerability and method for producing corresponding olefins from paraffins using the same

In the present disclosure, a heterogeneous nickel-based oligomerization catalyst in which nickel in the form of single atom is loaded on an Al-mesoporous silicate support by ion exchange and a method for producing the same, and a method for oligomerizing light olefins, specifically C4 olefins using the catalyst are described.

Nickel-based oligomerization catalysts and method for oligomerizing light olefins using the same

Disclosed is a process for converting methane into value-added compounds. In this process, a gas mixture containing hydrogen as well as high-concentration acetylene formed through methane pyrolysis (e.g. non-oxidative coupling of methane) is selectively hydrogenated in the presence of a bimetallic supported catalyst. This process obtains ethylene from acetylene in the gas mixture while unreacted methane and hydrogen are recovered as byproducts and/or additionally recycled.

Process of selectively hydrogenating gas mixture having high acetylene content

Disclosed herein are a dehydrogenation catalyst having single-atom cobalt loaded onto a silica support that has undergone pretreatment including a thermal treatment and a high-temperature aqueous treatment (reaction), a preparation method therefor, and a method for producing olefins by dehydrogenating corresponding paraffins, particularly light paraffins in the presence of the dehydrogenation catalyst.

Cobalt-based single-atom dehydrogenation catalysts having improved thermal stability and method for producing olefins from corresponding paraffins by using the same

In the present disclosure, a composite oxide catalyst capable of effectively suppressing side reactions at the time of dehydrogenation of C4 hydrocarbons having single bonds or one double bond and a process for preparing butadiene, in particular 1,3-butadiene, with a high selectivity and a high yield using the same are described.

Alkali metal and/or alkaline earth metal-doped transition metal-hydrogen active metal composite oxide catalyst and process for preparing butadiene using the same

Disclosed herein are a dehydrogenation catalyst having single-atom cobalt loaded on a silica-based, shaped support, a preparation method therefor, and a method for preparing an olefin by dehydrogenating a corresponding paraffin, particularly light paraffin in the presence of the dehydrogenation catalyst.
