Abstract
Processes for converting Fischer-Tropsch products into linear alkyl benzene (LAB) are described. By selecting a portion of the Fischer-Tropsch product stream, it can be fed to the alkylation reaction zone. Some pretreatment steps can be eliminated or reduced. Unreacted paraffins can be dehydrogenated and recycled to the alkylation reaction zone.
Claims19
A process for producing linear alkylated benzene comprising:
- providing a Fischer-Tropsch product stream comprising C10-C13 normal paraffins;
- alkylating the Fischer-Tropsch product stream with benzene in an alkylation reaction zone comprising an alkylation reactor in the presence of an alkylation catalyst to produce an alkylated effluent stream;
- and
- separating the alkylated effluent stream into an LAB product stream comprising linear alkyl benzene and a recycle stream comprising unreacted paraffins.

- separating the alkylated effluent stream into an LAB product stream comprising linear alkyl benzene and a recycle stream comprising unreacted paraffins, 1 wherein the LAB product stream has a linearity of greater than or equal to 70%;
- dehydrogenating the recycle stream in a dehydrogenation reaction zone comprising a dehydrogenation reactor in the presence of a dehydrogenation catalyst to produce a dehydrogenated effluent stream comprising C10-C13 mono and di olefins;
- and
- passing the dehydrogenated effluent stream to the alkylation reaction zone.
