NOVELTY - A biological regenerated diesel in kitchen garbage waste grease production comprises (pts. wt.) kitchen garbage waste grease (30-40), Barbados nut grease (25-35), rice bran grease (10-15), cotton seed grease (15-25), saponin grease (5-8), camphor grease (1-2), methanol (28-38), Tween T-80 (RTM: polyoxyethylene (20) sorbitan monooleate), Span S-80 (RTM: sorbitan monooleate) (0.5-1), petroleum ether (1-2), acetone (1-2), and sodium hydroxide (2-4).    USE - A biological regenerated diesel in kitchen garbage waste grease production.    ADVANTAGE - The product has the regeneration performance, thus solving the circulation of the kitchen garbage and meeting the relative rule of the kitchen garbage circulation and harmless treatment in the 36th document of the State Council 2010.    DETAILED DESCRIPTION - A biological regenerated diesel in kitchen garbage waste grease production comprises (pts. wt.) kitchen garbage waste grease (30-40), Barbados nut grease (25-35), rice bran grease (10-15), cotton seed grease (15-25), saponin grease (5-8), camphor grease (1-2), methanol (28-38), Tween T-80 (RTM: polyoxyethylene (20) sorbitan monooleate), Span S-80 (RTM: sorbitan monooleate) (0.5-1), petroleum ether (1-2), acetone (1-2), and sodium hydroxide (2-4). The kitchen garbage waste grease is the grease separated from the residual food in the hotel, guesthouse, catering industry, office, school and factory, hogwash water, inedible animal and plant grease and oil-water mixture by the machine after the oil-water separation. The Barbados nut grease is grease obtained by drying the fruit of Barbados nut, separating the seed, crushing, heating and vaporizing the seed, extruding by the machine. The rice bran grease is grease extracted by mechanical extraction method from rice bran separated from the machine production. The cotton seed grease is grease extracted by machine extraction by drying the cotton, machining the separated cotton seed, crushing, heating, and cooking the seed. The saponin grease is the grease extracted by machine extraction by drying the fruit, machining the separated cotton seed, crushing, heating, and cooking the seed. The camphor grease is the grease extracted by machine extraction by drying the fruit, separating the seed, crushing, heating, and cooking the seed. An INDEPENDENT CLAIM is included for a method for preparing a biological regenerated diesel in kitchen garbage waste grease production comprising mixing (pts. wt.) kitchen garbage waste grease (30-40), Barbados nut grease (25-35), rice bran grease (10-15), cotton seed grease (15-25), saponin grease (5-8), camphor grease (1-2), methanol (28-38), Tween T-80 (RTM: polyoxyethylene (20) sorbitan monooleate) (0.8-1.5), Span S-80 (RTM: sorbitan monooleate) (0.5-1), petroleum ether (1-2), acetone (1-2), and sodium hydroxide (2-4); preheating at 30-60 degrees C; adding in the reaction kettle; performing decoloration, esterification, separation; separating, filtering; and purifying by a centrifuge.
