Diesel Preperation by Chemicals

DIESEL PREPARATION

( A step Towards Alternative Fuel Energy Source )

By

Chemically Preparation of Diesel

Introduction :-

Biodiesel is an alternate of DIESEL and ts production is quite simple and in vehicles it does not need large number of changes we have to change its connection of fuel supply from Normal Diesel to Bio Diesel .

So to over come energy crisis or to reduce Environmental Pollution , we can use it and we can also produce it in a small plants .

Chemically Making Of Diesel :-

In making of Bio Diesel we used some oil made of Acids , Chemicals etc . Firs we take " Fatty-Acid / Triglyceride " its viscosity is to high so that we put it into a process namely " Transesterification " in this process we give a certain amount of heat to the reactant ( Fatty-Acid / Triglyceride ) and Alcohol in the presence of catalyst [ Sodium Hydroxide / Potassium Hydroxide ] , to produce Biodiesel ( Methyl Ester ) and Glycerol .

In this process , when we combined Alcohol with Catalyst , Triglyceride chemically broken with glycerides in the oil being replaced by Alcohol , forming a Fatty Ethyl Ester or Methyl Ester and produce Glycerol and METHYL ESTER as a by product

After process complete the mixture is reclaimed and separated in steps to isolate the Glycerol , Methyl Ester ( Alcohol ) is recycled and Bio Diesel is obtained .

Note :

" R " is a arbitrary " alkyl " that contain 3 Harbon atoms and 7 Hydrogen atoms in single bond .

Picture Presentation Of Chemical Process / Reaction :-

Steps To Obtained or to Make 1 Liter of Diesel :-

1 ) 0.2 Liter / 200 ml of Methanol .

2 ) 8 gr of Potassium Hydroxide [ KOH ] / 3.5 gr of Sodium Hydroxide [ NaOH ] ( Catalyser ) .

3 ) Catalyser dissolved in Alcohol .

4 ) Oil is per-heated at 50 - 60 *C

5 ) Both component are mixed together .

6 ) Before being settle mixture , it is heated at that temperature for 1.5 hours.

Future Working / Research :-

Working on Production of Diesel by Vegetable Oil and Animal Fat .
