METHOD FOR SORTING SPENT CATALYST AS A FUNCTION OF THE METALS OF THE CATALYST

摘要

A method and device for separating at least one catalyst from a mixture of homogeneously shaped catalysts, the catalysts comprising at least one metal selected from the group formed by Ni, Co, Mo, W, the catalyst to be separated comprising a characteristic metal selected from the group formed by Ni, Co, Mo, W and the other catalysts of the mixture not containing said characteristic metal, in which method:
the grains of the catalyst of said mixture pass in front of the LIES detection system,the presence of said characteristic metal in the catalysts is detected by the LIES technique, the wavelength being selected so as to detect said characteristic metal,the LIES detection system sends a signal to a means for evacuating grains of catalyst to be separated in a manner such as to separate said grains from the other catalysts of said mixture.

1. A method for separating at least one catalyst from a mixture of homogeneously shaped catalysts, the catalysts comprising at least one metal selected from the group formed by Ni, Co, Mo, W, the catalyst to be separated comprising a characteristic metal selected from the group formed by Ni, Co, Mo, W and the other catalysts of the mixture not containing said characteristic metal, in which method:
the grains of the catalyst of said mixture pass in front of the LIBS detection system, the presence of said characteristic metal in the catalysts is detected by the LIES technique, the wavelength being selected so as to detect said characteristic metal, the LIES detection system sends a signal to a means for evacuating grains of catalyst to be separated in a manner such as to separate said grains from the other catalysts of said mixture.
