    Abstract: A process for hydrocracking hydrocarbon-containing VD feedstocks allowing the improved production of middle distillates: a) hydrocracking of feedstocks in hydrogen and at least one hydrocracking catalyst, b) gas/liquid separation of effluent originating from a) producing a liquid effluent and a gaseous effluent with hydrogen, c) comprising the gaseous effluent before recycling into hydrocracking a), d) fractionation of liquid effluent into at least one effluent of converted hydrocarbon-containing products having boiling points less than 340° C. and an unconverted liquid fraction having a boiling point greater than 340° C., e) hydrocracking unconverted liquid fraction from d), in hydrogen and a hydrocracking catalyst, f) hydrotreating effluent from e) in a mixture with a hydrocarbon-containing gas-oil liquid feedstock having at least 95% by weight of compounds boiling at a boiling point between 150 and 400° C., hydrotreating f) operating in hydrogen and with at least one hydrotreating catalyst.

    Abstract: Process for hydrotreatment of hydrocarbon-containing feedstock comprising sulphur- and nitrogen-containing compounds, comprising: a) separating the feedstock into heavy and light fractions, b) a first hydrotreatment stage wherein the heavy fraction and hydrogen are contacted with a first hydrotreatment catalyst Z1 to produce a first desulphurized effluent, c) separating the first effluent into a first gaseous fraction and a first liquid fraction, d) purifying the first gaseous fraction to produce a hydrogen-rich flow, e) mixing the light fraction with the first liquid fraction to produce a mixture, f) a second hydrotreatment stage wherein the mixture from stage e) and the hydrogen-rich flow from stage d) are contacted with a second hydrotreatment catalyst Z2 to produce a second desulphurized effluent, g) separating the second effluent into a second gaseous fraction and a second liquid fraction, h) recycling at least part of the second gaseous fraction to b) as a flow of hydrogen.

    Abstract translation: 本发明涉及一种用于加氢处理包含硫和氮化合物的烃原料的方法，其包括以下步骤：a）将烃原料分离成重馏分和轻馏分; b）通过将重馏分和氢气流与第一加氢处理催化剂Z1接触来进行第一加氢处理步骤，以产生包含氢气，H 2 S和NH 3的第一脱硫流出物; c）将第一流出物分离成包含氢气，H 2 S和NH 3的第一气体馏分和第一液体馏分; d）纯化第一气体馏分以产生富氢流; e）将轻馏分与步骤c）中获得的第一液体馏分混合以产生混合物; f）通过将步骤e）中获得的混合物和步骤d）中产生的富氢料流与第二加氢处理催化剂Z2接触来进行第二加氢处理步骤，以产生包含氢气，NH 3和H 2 S的第二脱硫流出物; g）将第二流出物分离成包含氢气，H 2 S和NH 3的第二气体馏分和第二液体馏分; 和h）将第二气态馏分的至少一部分再循环到步骤b）作为氢气流。
