Fuel blends for homogeneous charge compression ignition engines

The present disclosure relates to novel processes for making improved blends of hydrocarbon fuels that provide increased power and a broader operating range when used as fuel for homogeneous charge compression ignition engines.

Processes for making homogeneous charge compression ignition engine fuel blends

A method to isomerize one or more wet hexanes in the presence of a catalyst comprising tungsten, zirconium and a Group VIII metal is provided.

Isomerization of wet hexanes

A process is disclosed for the alkylation of aromatics by charging a hydrocarbon feed containing aromatic hydrocarbons and olefinic hydrocarbons to a distillation column for separation into at least one fraction; removing an aromatics/olefin stream containing at least a portion of the aromatic hydrocarbons and at least a portion of the olefinic hydrocarbons; charging the aromatics/olefin stream to an alkylation reactor, operated at a temperature in the range of from about 80&#xb0; C. to about 220&#xb0; C., for alkylation of at least a portion of the aromatic hydrocarbons with the olefinic hydrocarbons; recycling at least a portion of the resulting reactor effluent to the distillation column; and removing a product stream containing alkylated aromatics from the distillation column.

Alkylation process

An isomerization process is disclosed including contacting a n-hexane hydrocarbon feed containing less than about 10 volume % naphthenic hydrocarbons with a catalyst to produce an iso-hexane containing product; wherein the catalyst is prepared by: a) incorporating tungsten on a zirconium hydroxide solid; b) drying and calcining the tungsten impregnated zirconium hydroxide; c) sizing the dried and calcined material to particle sizes between about 150 and about 600 microns; d) incorporating a Group VIII metal selected from the group consisting of nickel, platinum and palladium, and combinations thereof, on the sized material; e) drying and calcining the Group VIII metal impregnated tungsten/zirconia material; and f) contacting the second dried and calcined material with hydrogen in a reducing environment to form the catalyst which contains tungsten, zirconia and a Group VIII metal selected from the group consisting of nickel, platinum and palladium, and combinations thereof.
