Process for the preparation of a hydrocarbon mixture |
(57) Two-step process for the preparation of a hydrocarbon mixture with a desired RCT
and a desired initial boiling point (T,) from an asphaltenes-containing hydrocarbon
mixture with a higher RCT by hydrotreating the latter under such conditions that the
C
4- production per % RCT reduction (G) ist between 1.5 x G
c and 2.0 x G
c (G
c being the virtually constant G under less severe conditions), distilling off components
boiling below T, from the product obtained, and deasphalting the residue thus obtained
to such an extent that the desired RCT is achieved.
