“…The processes of hydro-treatment of heavy oil and petroleum residues in the presence of nanosized and ultra-dispersed catalysts without conventional solid carriers in the catalytic system have been actively studied in recent years due to the depletion of light and medium oil reserves and have shown high efficiency [1][2][3][4][5][6][7].…”

“…Currently, several hydrogenation processes using highly dispersed catalysts with the stated conversion efficiency of heavy oil feed (estimated by the residue conversion level 500 • C) over 90% are at the stage of pilot testing or introduction to the industrial scale. They include Russian Slurry Hydro-Conversion process (RSH) based on the TIPS RAS technology with suspended catalyst nanoparticles [1,8], Eni's EST technology [3], HTI's HCAT [9], Chevron's LC-slurry [10], and PVDSA-Intevep's HDH Plus [10].…”

Ex-Situ Synthesis and Study of Nanosized Mo-Containing Catalyst for Petroleum Residue Hydro-Conversion

2019

This study represents the results of ex-situ synthesis and research of the properties of concentrated suspensions with new catalysts for petroleum residue hydro-conversion. Suspensions were prepared and stabilized in a petroleum residue medium through reverse emulsions containing water-soluble Mo-precursor and S-containing agents (elemental sulfur, thiocarbamide) in the absence of a solid carrier. The resulting ex-situ catalyst dispersions had Mo content of 6-10 wt % and contained nanosized and submicron catalyst particles stabilized in a petroleum residue medium. The effects of S-containing agents on the properties of catalytic particles (sulfidation level, dispersity, structural and morphological features) were studied. The synthesis conditions for the optimal ex-situ catalyst providing the lowest coke yield (0.2 wt %) and the highest conversion (55.5 wt %) during petroleum residue hydro-conversion in a single pass mode have been determined.

The results of investigations on the processing of carbonaceous waste, namely, oil sludge and oil vacuum distillation residue (vacuum residuum) by hydroconversion in the presence of molybdenum catalyst in situ generated in the hydrocarbon medium are presented. A scheme for separation of heavy residue of the hydrocarbon part of the sludge has been developed. The characteristics of the vacuum residue of the sludge hydrocarbon part and the vacuum residue of oil distillation have been compared. It has been shown that a high degree of conversion of the heavy hydrocarbon part of oil sludge can be reached using the complex scheme of separation followed by hydroconversion in the presence of the molybdenum catalyst generated in situ in the hydrocarbon medium.
