Heating oil is one of the varieties of oil products, which has found application for heating of residential buildings and industrial plants, canning and drying of agricultural products, as well as in ores flotation at mining enterprises.
The main feature of heating oil is generation of large amounts of heat during combustion. At the same time, this oil product does not have any sharp and unpleasant smell. Heating oil is relatively inexpensive, which (together with the factors listed above) resulted in its popularity.
There are two types of fuel by color: dark and light. In most cases, the consumer logic is quite simple: the properties of dark fuel are close to ordinary furnace oil and those of light fuel are closer to diesel fuel. Buyers want to purchase a quality product at a price as low as possible, and at the subconscious level they tend to chose the second option.
What should the seller do? Is it possible to somehow balance the sales? Yes, it is. To do this, dark heating oil should be clarified. There are several ways to achieve this goal. We will not cover all of them, but focus on one of the simplest ways. We are talking about the use of activated charcoal.
Activated (active) charcoal is a porous substance with good sorbtion properties. There are many substances in nature which have a number of pores, but activated charcoal differs with its highly developed pore system in the first place, and, secondly, its high internal surface area (up to 1000 m²/g). The number of pores can be increased by activating this substance; hence, this charcoal gets its full name.
Activated charcoal is used in water treatment and purification, as well as in removing impurities from petroleum products, including clarification of heating oil.
