Hydroconversion of an atmospheric residue (AR) was performed in an autoclave with Mo, Ni, V compounds applied as precursors of the dispersed sulfide catalysts. The reaction was conducted at 450°C, residence time 1h and the catalyst concentration in the range of 300–900ppm. AR conversions were compared for the reaction carried out in the presence of sole metals and for the mixtures of two metals. By...
A continuous micro-pilot unit has been designed to convert petroleum residues with dispersed catalysts. Once-through and recycling modes can be operated. Several operating conditions (residence times and temperatures) have been investigated using the molybdenum naphthenate as catalyst precursor (600ppm). The micro-pilot hydrodynamics has been characterized via a cold mockup by Residence Time Distribution...
