The present invention relates to an NCC process and an apparatus for producing light olefins and aromatics, wherein the fraction comprising ethane and/or propane () from the cracking effluent is sent at least partly into a steam cracking furnace (), fed with steam (), to produce a steam cracking effluent () comprising ethylene and/or propylene.

Apparatus and process for producing light olefins by catalytic and steam cracking

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&#xb0; C. and an unconverted liquid fraction having a boiling point greater than 340&#xb0; 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&#xb0; C., hydrotreating f) operating in hydrogen and with at least one hydrotreating catalyst.

Process integrating two-stage hydrocracking and a hydrotreatment process

The invention relates to a process for purifying synthesis gas, comprising at least one stage for separating the crude synthesis gas to be treated into at least two effluents, namely a first part and a complementary part, in which the said first part is subjected to a carbon monoxide conversion stage with steam and the said complementary part is subjected to a COS and HCN catalytic hydrolysis stage, the two gas flows, namely the first part and complementary part, are then each treated separately in two stages intended to remove acid gases such as COand HS, by washing with aqueous solutions of specific amines, before a recombination stage of the two treated effluents.

Process for purifying synthesis gas by washing with aqueous solutions of amines

Process for hydrotreatment of hydrocarbon-containing feedstock comprising sulphur- and nitrogen-containing compounds, comprising:

Process for the hydrotreatment of a gas oil in a series of reactors with recycling of hydrogen

A process for the hydrotreatment of a hydrocarbon feedstock in which:
