PROTECTED RECOVERED METAL CATALYST Russian patent published in 2018 - IPC B01J33/00 B01J23/78 C10G2/00 C07C1/04 

FIELD: chemistry.

SUBSTANCE: in accordance with the present invention, a method of producing a protected recovered supported metal catalyst in the form of a granule or paste in which the said supported catalyst is in the form of a powder comprises contacting and mixing the said powder of the supported catalyst with a liquid in an inert atmosphere in such a manner that substantially all the surface of practically all the powder particles of the supported catalyst is coated with liquid. In this case, the amount of liquid corresponds to up to five times the amount of liquid required on the basis of the moisture capacity. The said liquid is selected from the group consisting of liquid C₁₀-C₁₃-aliphatic hydrocarbons subjected to hydrodesulfurization of heavy naphtha, white spiritates, tetralin, and combinations thereof.

EFFECT: fluid used to protect a catalyst against oxidation can easily be removed by distillation, these fluids not only protect the catalyst powder against oxidation, but also inhibit the spontaneous ignition of the protected catalyst.
