Abstract
A synthetic olefin/paraffin mixture useful for the production of linear alkybenzene and linear alkybenzene sulfonates. An integrated Fischer-Tropsch process to manufacture linear alkylbenzene and linear alkylbenzene sulfonates.
Claims46
A process to produce an alkylbenzenes comprising the steps of:
- (a) producing a synthetic crude by Fischer-Tropsch reaction of synthesis gas;
- (b) fractionating the synthetic crude at least into a naphtha stream, a light Fischer-Tropsch liquid, and a heavy Fischer-Tropsch liquid;
- (c) fractionating light Fischer-Tropsch liquid into at least a naphtha cut and a remaining light Fischer-Tropsch liquid stream;
- (d) reacting at least a part of the remaining light Fischer-Tropsch liquid stream over an alumina catalyst to dehydrate alcohols in the remaining light Fischer-Tropsch liquid stream to corresponding alpha- and internal-olefins and forming a dehydrated light Fischer-Tropsch liquid;
- (e) reacting the dehydrated light Fischer-Tropsch liquid with benzene to produce an alkylbenzene.

A feedstock for use in producing a linear alkylbenzene comprising:
- at least about 5 wt % olefins;
- at least about 5 wt % n-paraffins;
- and
- between about 2 and 80 wt % branched paraffins wherein substantially all of the branch groups are monomethyl and wherein the ratio of terminal monomethyl branching to internal monomethyl branching is at least about 1:1.5.
