Abstract:
A typical kind of waste Raneynickel catalyst was comprehensively analyzed by infrared spectrometry (IR), Xray powder diffractometry (XRD), inductively coupled plasmaatomic emission spectrometry (ICPAES), Xray 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 Raneynickel catalyst has been put forward.
