In this Quarter, the research was focused continually on the two general tasks: Task 1, molecular organometallic catalysts for hydrogenation and Task 2, organic base catalysts for arene hydrogenation and the hydrotreating of the coal liquids. With regards to Task 1, the [ 1,5-HDRhCl] suffer catalyst system has been investigated in detail to improve its performance. In the presence of CTAB ([CTA...

Abstract Understanding how hydrotreating oxygen-containing compounds together with nitrogen-containing affects the reactivity and selectivity is relevant for processing renewable feedstocks. In this work, competitive hydrodeoxygenation (HDO) hydrodenitrogenation (HDN) reactions were studied by co-hydrotreating palmitic acid (C16 acid) tetradecylamine (C14 amine) over a Pt/ZrO 2 catalyst in batc...

A highly dispersed nickel phosphide catalyst supported on SBA-15 was prepared and tested for the hydrotreating of tire pyrolysis oil (TPO). Physicochemical properties were analyzed by CO uptake chemisorption, BET, TEM, X-ray diffraction (XRD). An advanced technique with gas chromatography equipped mass spectrometry atomic emission detector applied to investigate carbon-, sulfur-, nitrogen-conta...

A study was made of the coking of a commercial fresh sulfide Ni-Mo/Al2O3 catalyst in a fixed-bed reactor. The catalyst was coked using different coke precursors in the gas oil under accelerated conditions at temperatures of 400 to 450°C to yield different deactivated catalysts containing 2-20 wt% C. Two cases were studied; crushed catalyst without diffusional ...
