Biodiesel obtained by transesterification of vegetable oils and fats is an alternative for petro-diesel fuel. Purification of biodiesel is one of the crucial steps in the production of biodiesel. The conventional wet washing of biodiesel involves huge quantities of water, energy, and time. Therefore, dry washing was carried out with raw bentonite …
and during refinery processing, and they are responsible for high acidity of oil products[1, 3-4]. The vacuum gas oils (VGOs) delivered from vacuum distillation unit at the refinery conventionally should undergo furfural refining, acetone-benzol dewaxing and clay refining to produce base oils for formulating lubricants [5]. Clay refining as an ...

The term "re-refining" is based on the fact the used oil is refined a second time after having been originally obtained when produced during a crude oil refining. Presently acid/clay re-refining processes are insufficient to recover good base stock from used oil. In relation to today's lubricating oils, modern re-refining technologies are ...
Clay treatment The filtered oil is again heated to about 100–110 °C for about 15 min during which the activated clay is added to the oil and continuous stirring is done. d. Neutralization The acidic nature of the oil can be neutralized by addition of sodium hydroxide/activated carbon which will improve the pH of the oil. e.
