NOVELTY - The method for producing BBN 100 (biofuel) as an alternative diesel fuel substitution material, comprises distillating (1time/stage) an oil waste from palm coconut through membrane/filter press, and adding methanol (99%) and 12 molar (concentration) (1-1.5 vol.%) of waste vegetable oil (WVO) sulfuric acid in a fluoresceine angiography (FFA) treatment unit reactor (R1A, R1B, R1C), which is the mixing reactor to obtain distillation flow. The reactor is continuously stirred tank reactor, which is operated at atmospheric pressure and at 60-70 degrees C for 60-90 minutes.    USE - The method is useful for producing a BBN 100 (biofuel) as an alternative diesel fuel substitution material.    ADVANTAGE - The method is capable of effectively producing the BBN 100 (biofuel) with improved physico and chemical characteristics such as physico state in the form of yellow-brownish liquid and chemical characteristics of 6 maximum acid number.    DETAILED DESCRIPTION - The method for producing BBN 100 (biofuel) as an alternative diesel fuel substitution material, comprises distillating (1time/stage) an oil waste from palm coconut through membrane/filter press, and adding methanol (99%) and 12 molar (concentration) (1-1.5 vol.%) of waste vegetable oil (WVO) sulfuric acid in a fluoresceine angiography (FFA) treatment unit reactor (R1A, R1B, R1C), which is the mixing reactor to obtain distillation flow. The reactor is continouly stirred tank reactor, which is operated at atmospheric pressure and at 60-70 degrees C for 60-90 minutes. The obtained distillation flow is supplied in an evaporator (E1), which is operated at 65 degrees C and at pressure (20-60 mmHg) for 60-90 minutes, and is proceeded in a distillation column (D1), which is to be distilled in operation condition at 65 degrees C and at pressure (20-60 mmHg) for 60 minutes. The fractions (top, bottom) of methanol and methyl ester have a temperature of 20 degrees C/65 degrees C with a concentration of 99%. The top/vapor fraction in the form of methanol is proceeded to stainless steel bait tank (TB1) through a condenser at temperature 20 degrees C in liquid condition. The bottom/liquid fraction in the form of water, glycerol, methanol and soap mixture is proceeded to bait tank (TB5) through a reboiler at temperature 65 degrees C in liquid condition. The obtained distillation flow of methanol with 99% concentration is restrained in the bait tank (TB1), and is proceeded to tank (R3), which is the mixing tank. The sodium- or potassium-hydroxide (1-1.5 wt.%) as catalyst and 99% methanol (10-15 wt.%) are included in the tank (R3) and then mixed to obtain sodium methanol. The waste vegetable oil in the form of oil waste of fruits/palm coconut or jatropha is evaporated at the evaporator and stored in pre reactor reserved (PR1) for 60 minutes for homogenic purpose, and is proceeded into reactor (R2A and R2B) through mixing tank (M1) together with the sodium methanol to obtain optimum methyl ester. The product obtained from R2A and R2B is removed through the bottom part of the reactor, and proceeded into pre reactor reserved (PR2) to obtain optimum result and into the distillation column (D2) having a specification of column packing. The top/liquid fraction in the form of glycerol, soap and methyl ester is recovered/withdrawn through the distillation column (D3), and proceeded to bait tank (TB2) through the condenser at temperature 20 degrees C in liquid condition. The bottom/liquid fraction in the form of methyl ester/biodiesel is proceeded to reactor (R4) through the reboiler at temperature 65 degrees c in liquid condition. The methyl ester/biodiesel is neutralized from pH 10 to become pH (5.5- 6) by adding sulfuric acid and water (10-15 vol.%), and then evaporated in evaporator (E2). The top fraction consisting of water, soap and salt is retained in the dirty water reserve tank (TB5), and the bottom fraction, which is the biodiesel 100 as the substitution of diesel fuel is reserved in the biofuel BBN-100 product tank.
