Abstract
An integrated Fischer-Tropsch process having improved alcohol processing capability is provided. The integrated Fischer-Tropsch process includes, optionally, synthesis gas production, Fischer-Tropsch reaction, Fischer-Tropsch reaction product recovery and, optionally, separation, catalytic dehydration of primary and internal alcohols, and, optionally, hydro-processing.
Claims41
In a Fischer-Tropsch process wherein a synthesis gas is catalytically converted into a Fischer-Tropsch reaction product mixture comprising paraffins and oxygenates and wherein the oxygenates include primary and internal alcohols, the process improvement comprising:
- (a1) passing all or part of the Fischer-Tropsch reaction product mixture over at least one bed packed with an alumina catalyst to dehydrate substantially all of the alcohols to their corresponding olefins.
An integrated Fischer Tropsch process 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 light Fischer Tropsch liquid, and a heavy Fischer Tropsch liquid;
- and
- (c) reacting at least a part of the light Fischer Tropsch liquid over an alumina catalyst to dehydrate alcohols in the light Fischer Tropsch liquid to corresponding alpha- and internal-olefins and forming a dehydrated product.
