Abstract

A new Ni–Mo/Al2O3-based nano catalyst composition was developed and manufactured by a proprietary catalyst preparation technology for diesel hydrotreatment. The nanocatalyst has been performing commercially since September 2011, consistently producing ultra low-sulfur diesel of Euro-IV/V standards from a feedstock containing 1.75 wt% sulfur. In addition to lowering sulfur content, the catalyst also enhances cetane number and reduces boiling end-point to obtain diesel with better quality. The nanocatalyst was characterized by X-ray photoelectron spectroscopy to ascertain the electronic state of metal species. The morphological characterization of the nanocatalyst carried out by TEM revealed the presence of nano-sized MoS2 slab structures. The performance of the nanocatalyst is mainly attributed to MoS2 slabs with increased stacking which in turn are generated from the customized metal-sulfide precursors.
