Catalyst for converting light olefin to aromatics, method of making and method of using the same
A catalyst for converting hydrocarbon, a method of making the same, and a method of using the same are provided. Such a catalyst includes a zeotype microporous material, a binder material, and a metal phosphide, which can be in a range of from 0.01% to 10% by weight of a total weight of the catalyst. For example, such a catalyst can be used to convert light alkene or alkane into aromatic hydrocarbon such as benzene, toluene, xylenes, and a combination thereof. The alkene may be ethylene, propylene, butylene, or a combination thereof. The alkene may be supplied directly or from a stream converted from light alkane such as methane, ethane, propane, butane, or a combination thereof.
PHOSPHATE-PROMOTED NICKEL CATALYST FOR HIGH TEMPERATURE OLIGOMERIZATION
An oligomerization catalyst, oligomer products, methods for making and using same. The catalyst can include a supported nickel phosphate compound. The catalyst is stable at oligomerization temperatures of 500° C. or higher and particularly useful for making oligomer products containing C4 to C26 olefins having a boiling point in the range of 170° C. to 360° C.
METHOD OF SYNTHESIZING HIGH-EFFICIENCY BIFUNCTIONAL ELECTROCATALYSTS
The design of bifunctional catalysts for water splitting by modifying the electronic structure of the catalyst. That bifunctional catalyst that is synthesized is a quaternary FeNi—PSe nanoporous film (FeNi—PSe NF). A self-supported FeNi—PSE NF is synthesized and used as an anode and a cathode in a two-electrode electrolytic cell. The cell is subjected to a water source, and the FeNi—PSe NFs split the water molecules to produce hydrogen fuel. The slightly oxidized FeNi—PSe surface serves as an active site for oxygen evolution reactions, making hydrogen evolution reactions and oxygen evolution reactions well-balanced, thereby improving electrolysis efficiency.
