Patent ID: 7803269

Claim:
A process for improving the cold flow properties of a hydrocarbon stream, the process comprising: providing a hydrocarbon feed stream having a cloud point, a pour point, and a CFPP value; taking at least a portion of the hydrocarbon feed stream as a hydroprocessing feed; admixing an amount of hydrogen with the hydroprocessing feed, the hydrogen in a form available for substantially consistent consumption in the substantially liquid-phase continuous hydroisomerization zone; directing the hydroprocessing feed to the substantially liquid-phase continuous hydroisomerization zone; and reacting the hydroprocessing feed undiluted with another hydrocarbon stream in the substantially liquid-phase continuous hydroisomerization zone using at least a hydroisomerization catalyst at hydroisomerization conditions effective to produce an effluent having at least one of a reduced cloud point, a reduced pour point, and a reduced CFPP value relative to the cloud point, pour point, and CFPP value of the hydrocarbon feed stream.
