Title
Study on high-performance unsupported Ni–Mo–W hydrotreating catalyst
Abstract

A new unsupported hydrotreating catalyst with binder has been prepared by a reflux method. BET, XRD, TEM characterization results show that the catalysts have high surface area and dense active phase. Pilot plant results also show that the new catalyst exhibits much better hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) performance than the traditional supported catalyst.

Graphical AbstractAccording to the TEM results, the highly active unsupported Ni–W–Mo catalysts B5 and B8 have more MoS2/WS2 stacking layers than the supported catalyst, which means the increase of active sites in the unsupported catalysts.Figure optionsDownload full-size imageDownload as PowerPoint slideResearch highlights► Highly active unsupported catalysts with binder were prepared. ► BET and XRD show the unsupported catalysts have high surface area and pore volume, highly divided active phase. ► TEM demonstrates the unsupported catalysts have dense active sites. ► Pilot plant test shows the unsupported catalysts exhibit good HDS and HDN performance.
