- Abstract
The possibility of involvement of diesel fractions obtained from petroleum waste in hydrotreating feedstock for the manufacture of diesel fuels that meet the Euro-4 and Euro-5 standards has been studied. The hydrogen treatment of a mixed feedstock, composed of diesel fractions of oil sludge (DFS), straight-run diesel fraction (SDF), and light catalytically cracked gas (LCCGO), conducted in a laboratory flow unit using the HTRU-120 CoMo/AlO catalyst (340-360°C, 3.5 and 4.0 MPa, LHSV of 1.5-2.0 h, the hydrogen : feedstock ratios of 350 and 500 nL/L) has revealed that DFS can be used as a feedstock component for hydrotreating units used to manufacture diesel fuel that meets the Euro 4 and Euro 5 standards. If the process parameters of severe hydrogen treatment are maintained, as large an amount of DFS as 5 wt % can be involved in the hydrotreating unit feedstock. The samples of stabilized hydrogenation products obtained from this feedstock meet all the requirements of GOST (State Standard) R 52368-2005.
