Optimized homopolymer absorbent material used for removing free water from emulsified liquid fuels such as hydrocarbons derived from petroleum and biofuels such as blends of diesel and biodiesel, comprises acrylamide monomer

NOVELTY – Optimized homopolymer absorbent material comprises 2-5 wt.% of acrylamide monomer and 2-4 wt.% of methylenebisacrylamide as a cross-linking agent. The liquid fuel is selected from hydrocarbons derived from petroleum, biofuels and blends of diesel with biodiesel. USE – Optimized homopolymer absorbent material used for removing free water from emulsified liquid fuels such as hydrocarbons derived from petroleum and biofuels such as blends of diesel and biodiesel. ADVANTAGE – The optimized homopolymer absorbent material provides efficient removal of free water without direct contact with fuel. DESCRIPTION OF DRAWING(S) – The drawing shows a graphical representation depicting monitoring degree of swelling of hydrogel. (Drawing includes non-English language text).
