Abstract(s)
In the year 2020, global biodiesel production reached 46.45 million tons, with biodiesel from waste
cooking oils (WCO) constituting approximately 10% of this total, with Europe accounting for
approximately 33% and Brazil 12% of global production [1]. The cost of conventional biodiesel
production is higher than the production of diesel from petroleum, since it is produced mainly from
high quality virgin oils, it is estimated that 70 to 80% of the total cost of biodiesel production is
associated with the cost of the raw materials [2]. With this perspective, biodiesel production from
WCO has become an economic opportunity and an environmental strategy to help address global
renewable energy challenges and contribute to a sustainable society [3]. Oil with hours of frying at
high temperatures results in the loss of its edible properties and nutritional value, the disposal of used
cooking oil remains an issue due to its environmental and human health threats [4]. In this scenario,
the collection and destination of these oils for the production of a value-added and environmentally
friendly biofuel presents itself as an opportunity to be investigated. Adsorption and ion exchange are
the most commonly used affinity separation processes in biodiesel purification worldwide, these
methods are also known as dry washing methods. In these processes, an appropriate adsorbent is
used to selectively remove certain impurities from the liquid phase onto its surface. Dry cleaning offers
several advantages, including simple integration into an existing plant, shorter purification time, lower
water consumption and lower effluent generation
