PROCESS TO PREPARE TWO ISO PARAFFINIC PRODUCTS FROM A FISHER-TROPSCH DERIVED FEED

摘要

Process to prepare an iso-paraffinic product having a carbon range of Cx to Cy and a iso-paraffinic product having a carbon range of Cn to Cm from a Fischer-Tropsch derived feed by performing the following steps, (a) obtaining from the Fischer-Tropsch derived feed at least two different compositions (i) and (ii), which composition (i) has a greater fraction of compounds in the carbon range of C2n to C2m than composition (ii) and composition (ii) has a greater content of C2x to C2y than composition (i); (b) performing separately a hydroconversion/ hydroisomerisation step on feed compositions (i) and (ii) and isolating from the thus obtained effluents the iso-paraffinic product having a carbon range of Cx to Cy and the iso-paraffinic product having a carbon range of Cn to Cm.
