    摘要: A process is disclosed for the removal of metals contaminants, particularly calcium, from hydrocarbonaceous feedstocks. The process comprises mixing the feedstock with an aqueous solution of a metals sequestering agent, particularly hydroxocarboxylic acids, especially citric acid, then salts or mixtures thereof, and separating the aqueous solution containing the metals from the demetalated feedstock.

    摘要: A process for the production of transportation fuels from heavy hydrocarbonaceous feedstock is provided comprising a two-stage, close-coupled process, wherein the first stage comprises a hydrothermal zone into which is introduced a mixture comprising a feedstock and dispersed activated or presulfided red mud having demetalizing and coke-suppressing activity, and hydrogen; and the second, close-coupled stage comprises a hydrocatalytic zone into which substantially all the effluent from the first stage is directly passed and processed under hydrocatalytic conditions.
