    摘要: A process for the economical and environmentally acceptable disposal of spent adsorbent recovered from an adsorption column used to remove HPNA compounds and HPNA precursors from hydrocracking unit bottoms and/or recycle streams includes removing the liquid hydrocarbon oil from the spent adsorbent material by a combination of solvent flushing, and/or heating and vacuum treatment, grinding the dried adsorbent material containing the HPNA compounds and HPNA precursors to produce free-flowing particles of a predetermined maximum size, and introducing the particulate adsorbent material into a membrane wall partial oxidation gasification reactor to produce hydrogen and carbon monoxide synthesis gas, or syngas, which can be further processed by the water-gas shift reaction to increase the overall hydrogen recovered from the initial feed to the gasifier.

    摘要: An hydroconverted effluent composition is provided, along with systems and methods for making such a composition. The hydroconverted effluent composition can have an unexpectedly high percentage of vacuum gas oil boiling range components while having a reduce or minimized amount of components boiling above 593°C (1100°F). In some aspects, based in part on the hydroprocessing used to form the hydroconverted effluent composition, the composition can include unexpectedly high contents of nitrogen. Still other unexpected features of the composition can include, but are not limited to, an unexpectedly high nitrogen content in the naphtha fraction; and an unexpected vacuum gas oil fraction including an unexpectedly high content of polynuclear aromatics, an unexpectedly high content of waxy, paraffinic compounds, and/or an unexpectedly high content of n-pentane asphaltenes.

    摘要: The invention provides a process for producing middle distillates from a residual hydrocarbonaceous feedstock, comprising the steps of: (a) thermally cracking the residual hydrocarbonaceous feedstock in a first thermal cracking unit to obtain a thermally cracked product comprising a thermally cracked residue; (b) deasphalting at least the thermally cracked residue to obtain a thermally cracked deasphalted oil and an asphaltic product; (c) thermally cracking at least part of the thermally cracked deasphalted oil in a second thermal cracking unit to obtain a twice thermally cracked deasphalted oil; (d) hydrocracking at least part of the twice thermally cracked deasphalted oil as obtained in step (c) to obtain a hydrocracked product; and (e) subjecting at least part of the hydrocracked product as obtained in step (d) to a separation treatment to obtain at least a middle distillate fraction. The invention further provides a process for producing ultra-low sulphur fuel oil and middle distillates and a low-sulphur fuel oil or fuel oil blending component having a sulphur content in the range of from 0.03%wt. to less than 0.5%wt.
