Composition Analysis of Waste RaneyNickel Catalyst

A typical kind of waste Raneynickel catalyst was comprehensively analyzed by infrared spectrometry (IR), Xray powder diffractometry (XRD), inductively coupled plasmaatomic emission spectrometry (ICPAES), Xray photoelectron spectrometry (XPS), scanning electron microscopy (SEM), elemental analysis (EA) and gravimetric method. There is a high nickel content in the waste catalyst so that it is worthy of recycling. The quantification for some components in the waste catalyst including nickel, aluminum, calcium, iron, molybdenum, copper and silicon, as well as qualitative analysis for some components has been carried out. The technical protocol of the recycling from waste Raneynickel catalyst has been put forward.
