Abstract

Abstract: Insights into the nickel sulphide speciation of a dried oxidic Ni catalyst supported on delta-alumina were obtained by temperature-programmed sulphidation monitored by Quick-X-ray absorption with online mass spectrometry. Combination with Raman spectroscopy enabled the phase identification of sulphide phases isolated by multivariate curve regression with alternating least square analysis of the time-resolved X-ray absorption spectroscopy data.
