Abstract

Спосіб отримання дизельного біопалива з відпрацьованих олій включає процеси фільтрації з відділенням супутніх домішок, нейтралізації вільних жирних кислот, промиванні олії сольовим розчином і водою, очищенні від домішок та переестерифікації. Використовується відпрацьована олія з вмістом вільних жирних кислот 20-40 мг КОН/г, а їх нейтралізація здійснюється проведенням реакції естерифікації концентрованою сірчаною кислотою - двічі 5 % до маси, протягом 2 год. за температури 60-65 °С при постійному перемішуванні з відділенням води і спирту, при чому, метанол і сірчану кислоту беруть у молярному співвідношенні 6:1 та направляють на переестерифікацію з додаванням метанолу і каталізатора - КОН.The method of producing diesel biofuels from waste oils involves filtration processes with separation of associated impurities, neutralization of free fatty acids, washing the oil with saline and water, impurity purification and transesterification. Used waste oil with a content of free fatty acids 20-40 mg KOH / g, and their neutralization is carried out by esterification with concentrated sulfuric acid - twice 5% by weight, for 2 hours. at a temperature of 60-65 ° C with constant stirring with the separation of water and alcohol, whereby methanol and sulfuric acid are taken in a molar ratio of 6: 1 and sent for transesterification with the addition of methanol and catalyst - KOH.
