Presentation Transcript

  1. Total Acid Number Determination • Total acid number of biodiesel • Distilled biodiesel experiment • Ultra low sulfur diesel (ULSD) experiment

  2. Total Acid Number • Definition The mass of potassium hydroxide (KOH) in milligrams that is required to neutralize the acids in one gram of oil. • Formula Veq :Titrant consumed by sample+spiking solution beq :Tiltrant consumed by spiking solution N: Molarity of titrant

  3. Factors Contributing to the TAN • FFA • Esters • Catalyst oxides • Salts of heavy metals • Additives such as inhibitors and detergents ……

  4. Potentiometric Titration • The sample is dissolved in toluene and propanol with a little water • Titrated with alcoholic potassium hydroxide • A glass electrode and reference electrode is connected to a voltmeter/potentiometer. • The meter reading (in millivolts) is plotted against the volume of titrant. • The end point is taken at the distinct inflection of the resulting curve corresponding to the basic buffer solution.

  5. Acid used in the experiment • Calculated amounts of palmitic acid was added to the oil to determine total acid numbers (TANs)

  6. Experiment Results: Distillated SBO-biodiesel • TAN of ND B100: 0.177mgKOH/g • TAN(mgKOH/g) of distilled BD100 from Capila

  7. Experiment Results Based on ULSD

  8. Current Work • Synthetic antioxidants by GC-MS • Acid number • Writing proposal • Catalyst activities
