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).
