摘要： The present invention relates to a zeolitic granular material having a connected zeolitic structure across the entire volume thereof, having high mechanical resistance to crushing in the bed, and optimised material transfer in the macro-mesopores. The invention also relates to the method for preparing said zeolitic granular material, as well as to the use thereof as an adsorbent material in co-current or counter-current liquid phase separation methods, typically in a simulated mobile bed.

摘要： A subject matter of the invention is a process for the hydrotreating of a hydrocarbon feedstock having a distillation range of between 150° C. and 600° C., so as to obtain a hydrotreated effluent, said process comprising the following stages:



a) said hydrocarbon feedstock is brought into contact, in the presence of hydrogen, with at least one first catalyst occupying a volume V1 and comprising a support based on alumina or silica or silica-alumina and an active phase consisting of nickel and molybdenum,
b) the effluent obtained in stage a) is brought into contact, in the presence of hydrogen, with at least one second catalyst occupying a volume V2 and comprising a support based on alumina or silica or silica-alumina and an active phase consisting of nickel, molybdenum and tungsten, and phosphorus,

the distribution of the volumes V1/V2 being of between 50% vol/50% vol and 90% vol/10% vol respectively.

摘要： The present invention describes a process for treating a feedstock obtained from a renewable source, comprising a step a) of hydrotreating said feedstock, a step b) of separation into at least a light fraction and at least a hydrocarbon liquid effluent, a step c) of removing at least a portion of the water from the hydrocarbon liquid effluent, a step d) of hydroconversion of at least a portion of the hydrocarbon liquid effluent, said hydroconversion step d) being characterized firstly by the use of a bifunctional catalyst comprising a molybdenum and/or tungsten sulfide phase promoted with nickel and/or cobalt and secondly by a ratio between the partial pressure of hydrogen sulfide and of hydrogen at the inlet of the hydroconversion unit of 10 less than 5×10−5 and a step e) of fractionation of the effluent obtained from step d) to obtain at least a middle distillate fraction.
