摘要： The present invention describes a process for the simulated moving bed separation of xylenes, in which the operating conditions are optimized by means of a specific relationship between the cycle time and the flow rate of the desorbant.

摘要： The present invention describes a process for the simulated moving bed separation of xylenes which can be used for the treatment of paraxylene-rich feeds (more than 25% by weight of paraxylene), in which the operating conditions are optimized by means of a specific relationship between the cycle time and the desorbant flow rate.

摘要： Process for the production of olefins and of middle distillates from a paraffinic feedstock, in which: a) a paraffinic feedstock resulting from a Fischer-Tropsch unit is recovered, the said feedstock containing a light fraction and a heavy fraction; b) the light fraction is sent to a catalytic cracking unit; c) the effluent resulting from the catalytic cracking unit is separated in a fractionation unit in order to obtain a fraction of light hydrocarbons, an olefinic fraction and a residual liquid fraction; d) the heavy fraction is sent to a hydrocracking/hydroisomerization unit; e) the effluent resulting from the hydrocracking/hydroisomerization unit is separated in a fractionation unit in order to obtain a middle distillates fraction, a naphtha cut having a maximum boiling point of less than 180° C. and an unconverted heavy fraction; f) a part of the naphtha cut resulting from the fractionation unit is sent to the catalytic cracking unit.
