Abstract
The present invention relates to a normal paraffin composition comprising from 45 to 60 wt. % of a fraction of normal paraffin having from 10 to 13 carbon atoms and from 40 to 55 wt. % of a fraction of normal paraffin having from 14 to 18 carbon atoms.
Claims9
A normal paraffin composition comprising from 45 to 60 wt. % of a fraction of normal paraffin having from 10 to 13 carbon atoms and from 40 to 55 wt. % of a fraction of normal paraffin having from 14 to 18 carbon atoms.
A process to prepare a normal paraffin composition comprising the following steps:
- (a) providing a Fischer-Tropsch product stream;
- (b) separating the Fischer-Tropsch product stream of step (a), thereby obtaining a gaseous hydrocarbon stream and a first liquid hydrocarbon stream;
- (c) cooling of the gaseous hydrocarbon stream of step (b) in one or more steps to obtain a second liquid hydrocarbon stream and a third liquid hydrocarbon stream;
- (d) subjecting the second and third liquid hydrocarbon streams of step (c) to a hydrogenation step, thereby obtaining a hydrogenated liquid hydrocarbon stream;
- (e) separating the hydrogenated liquid hydrocarbon stream of step (d) by one or more atmospheric distillation(s), thereby obtaining at least a normal paraffin composition comprising a fraction of normal paraffin fraction comprising 10 to 13 carbon atoms and a fraction of normal paraffin fraction comprising 14 to 18 carbon atoms, a normal paraffin fraction comprising 5 to 9 carbon atoms, and a hydrogenated normal paraffin fraction comprising 19 to 35 carbon atoms.
A process to prepare linear alkyl-benzene sulphonate using a normal paraffin fraction comprising 10 to 13 carbon atoms.
