The fractionating column is usually filled with glass or plastic beads. These beads improve the separation between the liquids being distilled. The reason that fractional distillation gives better separation between the liquids is because the glass beads in the fractionating column provide "theoretical plates" on which the refluxing liquid can condense, re-evaporate, and condense again, essentially distilling the compound over and over. The more volatile liquids will tend to push towards the top of the fractionating column, while lower boiling liquids will stay towards the bottom, giving a better separation between the liquids.
A fractionating column is used to separate a mixture into component parts based on their volatility. Volatility is defined as the tendency to vaporize in chemistry.
Fractionating columns are used to separate mixtures into respective components or fractions based on relative volatilities.
This a chemical laboratory apparatus or an idustrial installation used for the separation of liquids, based on the difference between boiling points.
Fractionation is based on the differences between boiling points of components.
distillation column
Fractional Distillation. Performed in a fractionating column. Heat is applied to the crude oil and it vaporises. Fractions with different boiling points rise to specific heights within the fractionating column, where they are condensed and extracted.
The process is distillation based on vaporization.
using fractional distillation. first crude oil is heated up until it turned to gas and the residue (bitumen) goes through the most bottom pipe to be used for tar macing roads. The fractionating column has different fraction that are at different temperatures (gets colder as you go up). And because hydrocarbons got different boiling point (the longer the hydrocarbon, the higher the boiling point), the gas then travels up and as certain hydrocarbons got to the fraction below their boiling point they turn from gas to liquid and go through the pipe to be used.The fractional distillation goes in this order:-(shortest chain/lowest boiling point)LPGPetrolParaffinLight Gas OilDieselLubricating SubstancesBitumen(longest chain/highest boiling point)Hope this help! (if not don't blame me, I'm only 14!)
Fractional distillation it is separating mixtures via their boiling points. Fractional distillation is done by adding some sort of material into the column that the vapor travels before being cooled and condensed while. Since the fractional distillation means the separation of a mixture into different componenets.Suppose the raw material entering into the distillation column contains many fraction(for example,if a crude oil is entering,it contains gases,gasoline,kerosene etc). if a distillation is done for such a material.this will be the fractional distillation.Because in a distillation column you will separate different components present in the crude Check the related question below to know more.

Kerosine (sometimes spelt kerosene) is a mixture of hydrocarbons that is a fraction from the fractional distillation of petroleum extracted between 150 and 200 0C. See wikipedia -fractional distillation for a diagram of an industrial fractionating column
This is an installation used for separation by distillation.

why does temprature fall down toward the end of the fractional column
The process is distillation based on vaporization.
The outer jacket on a fractionating column is used to insulate against heat loss from the inner jacket during distillation.
Depending on the boiling points of the various components in a complex mixture, the pure components can be obtained and the process is known as fractional distillation. The distillation efficiency can be further increased by increasing the fractional column surface area. The aim of fractional distillation is to achieve high purity of components.

Fractional Distillation, an experiment using a Fractionating column that the gas passes through after it is heated, before going into a condensing tube where it turns back into a liquid and pours into a test tube. Each of the liquids at the start have different boiling points, so they turn into a gas and go through the apparatus at separate times.
The height of a column used in fractional distillation is dependent on the number of theoretical plates needed to sufficiently separate a mixture divided by the height equivalent to theoretical plate HETP. Nt=H/HETP
