Abstract:
The present application is directed to systems and methods for on-board fuel separation. The system includes: a source fuel tank for liquid fuel; a pump; and a membrane module. The membrane module includes a hydrophilic membrane, a retentate channel, and a permeate channel. The retentate and permeate channels are on opposing sides of the membrane. The membrane module receives fuel from the source fuel tank and separates the liquid fuel into a high octane fraction that collects in the retentate channel and a low octane fraction that diffuses through the membrane to the permeate channel. The system further includes a low octane fuel tank for receiving at least a portion of the low octane fraction, a high octane fuel tank for receiving at least a portion of the high octane fraction, and an engine configured to selectively receive at least a portion of the low and high octane fractions.

Claim (Index 6):
A system for on-board fuel separation using membrane distillation, the system being mounted in a vehicle and comprising:\n a source fuel tank comprising liquid fuel; a pump configured to deliver the liquid fuel from the source fuel tank; a membrane module comprising a hydrophilic membrane, a retentate channel, and a permeate channel, the retentate and permeate channels being disposed on opposing sides of the hydrophilic membrane, wherein the retentate channel is configured to receive the liquid fuel from the source fuel tank via a feed channel, and wherein the membrane module is configured to separate the liquid fuel into a high octane fraction that remains in the retentate channel and a low octane fraction that diffuses through the hydrophilic membrane to the permeate channel; a gas channel fluidly connected to the permeate channel and configured to deliver a sweeping gas to the permeate channel; a flash tank fluidly connected to the permeate channel and configured to selectively receive at least a portion of the low octane fraction and the sweeping gas, and to separate the low octane fraction from the sweeping gas; a low octane fuel tank configured to receive the separated low octane fraction from flash tank; a high octane fuel tank configured to receive the high octane fraction from the retentate channel; and an engine fluidly connected to the permeate channel and configured to selectively receive at least a portion of the low octane fraction and at least a portion of the high octane fraction.
