Biodiesel from tilapia engine oil and the production process.

Abstract

OCR This invention adds value to waste materials from seafood processing by utilizing tilapia offal. It is a primary raw material in oil extraction for biodiesel production, resulting in high-quality biodiesel that can reduce costs. The cost of biodiesel production can be reduced.

Claims

OCR Claim 1: A method for producing biodiesel from engine oil in tilapia, consisting of the following steps: As follows:

1. Step 1: Extracting oil from tilapia offal. A. Grind the tilapia offal using a blender at a speed of 18,000 revolutions per minute. Duration: 30 seconds B. Mix the tilapia offal (from step A) with water in a ratio of 1 to 5 (weight to volume). Stirring at a speed of 250 revolutions per minute for 60 minutes at a temperature of 80 degrees Celsius. C. Filter the mixture through cheesecloth and centrifuge at a speed of 20,000 revolutions per minute. The temperature was 28 degrees Celsius for 10 minutes. d. Take the top portion obtained (from step c) and bake it in a hot air oven at 105 degrees Celsius. The evaporation process takes 60 minutes to remove water, resulting in oil extracted from the tilapia offal.

2. Step 2: The process of producing biodiesel from engine oil in tilapia. A. Biodiesel is produced by combining oil from tilapia offal and methanol in a ratio of oil to methanol. Tanol in a 1:4 ratio (by moles), with 1% deionized water (DI) added. (Weight of oil) Add lipase enzyme at a level of 20 kilouncture units (1 unit is the amount of enzyme released). Nitrophenol (p-nitrophenol) increased by 0.001 per minute at 37 degrees Celsius, pH 8.0, with... p-nitrophenyl palmitate is a precursor. B. Shake continuously at a speed of 200 revolutions per minute at a temperature of 35 degrees Celsius. For 18 hours, using a temperature-controlled shaking water bath. C. After the specified time, separate the samples by centrifuging them at a speed of 5,000 x rpm. After 10 minutes of centrifugation, the sample was stratified. The top layer, which is the outermost layer, was separated. Biodiesel can be obtained from the engine oil in tilapia.
