Аннотация:The paper presents the results of studies aimed at obtaining experimental
data for development of technological solutions to the production of marketable
petrochemicals and petroleum products from heavy oil wastes using the process of
hydroconversion and at designing engineering solutions in the area of preliminary
treatment of heavy oil wastes for their further processing into marketable petrochemicals
and petroleum products. The experiments have been conducted using a
bench for heavy oil waste processing which combines pretreatment of oil wastes
and subsequent hydroconversion processing in the presence of highly efficient
ultrafine catalysts. Optimum conditions of oil sludge heavy residue hydroconversion
(pressure, 7 MPa; temperature, 435 °C; feedstock space velocity, 1 h−1;
hydrogen: feedstock, 1000 nL/L; catalyst (Mo) content, 0.05 wt%; H2O, 2 wt%
(based on the feedstock) make it possible to achieve conversion of the 520 °C
+ fraction of feedstock of up to 67 wt% (per pass) or 90 wt% (based on the recycle
stock).
