Abstract: The present invention relates to a process and a device for the conversion of aromatic compounds, in which the aromatic compounds of a hydrocarbon feedstock (1) comprising aromatic compounds containing 9 carbon atoms are isomerized in an isomerization unit (A) in the presence of a bifunctional isomerization catalyst having a hydro/dehydrogenating function and a hydroisomerizing function, to produce an isomerization effluent (10) enriched in trimethylbenzenes. The present invention also relates to a process and a device for the production of aromatic compounds, comprising the process and the device for the conversion of aromatic compounds.

Abstract: The present invention relates to a process for purifying a crude diester monomer feedstock comprising:
a) a step of mixing the crude diester monomer feedstock with an aqueous solvent, at a temperature of between 60° C. and 150° C., in order to obtain a diester monomer aqueous mixture, the amount of aqueous solvent introduced being adjusted so that the crude diester monomer feedstock represents between 20% and 90% of the total weight of the diester monomer aqueous mixture;
b) a step of adsorbing the diester monomer aqueous mixture, at a temperature of between 60° C. and 150° C. and a pressure of between 0.1 and 1.0 MPa, in order to obtain a purified monomer effluent.-

Abstract: 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.-
