In-situ diffuse reflective infrared Fourier transform spectroscopy (DRIFTS) study on Ni passivation in FCC catalysts from boron-based technology

Summary: Fluid Catalytic Cracking (FCC) is a crucial refining process that provides the majority of gasoline and key building blocks for the chemical industry worldwide. Nickel, a contaminant in crude oil, can inhibit optimal operation of the FCC unit by inducing unwanted dehydrogenation reactions. A new spectroscopic methodology has been developed to characterize the impact of boron interaction on nickel in FCC catalysts, showing that boron can passivate nickel by decreasing its reducibility.
