Industrial applications of pistachio shell

1- Tar production

Production of tar from pistachio skin

 

Production of tar from pistachio skin

The most important and valuable product obtained from the chemical decomposition of hard pistachio skin due to high heat is tar. pistachio shell

 

On average, 15-20 ml of tar is obtained from each 100 grams of pistachio shell.

 

Tar is a viscous liquid with a pungent smell that contains all kinds of different chemical compounds and is obtained from the chemical decomposition of materials such as coal and wood, etc. due to high heat.

The tar in the pistachio skin is edible due to its high index.

 

Therefore, in terms of economic value, it has a higher price than tar obtained from wood. Tar has many uses in the pharmaceutical industry.

For example, Sharben tablets, which are the most used in the anti-flatulence group in humans, are obtained from coke obtained from the hard shell of pistachios. Also, this tar is of high quality and has the effective substance Hydroxanthraquinone; The following drugs are used.

 

1- Piralox with the aim of treating mouth sores and ulcers

2- Iralox with the aim of controlling bacteria and fungi in the mouth

 

Because hydroxyquinones are prepared from phenolic compounds and phenolic compounds are obtained from the tar obtained from burning the shell, pistachio waste can be a suitable source for preparing some drugs, especially antiseptic drugs. The best solvent for pistachio skin tar is diacetone alcohol. In order to analyze and identify the best compounds in pistachio shell tar, you can use gas chromatography.

 

2- Production of activated carbon

Production of activated carbon from pistachio bone skin

At the end of pistachio shell pyrolysis, some coal remains, which is used to prepare activated carbon. Activated carbons are microporous carbon adsorbents that have important and vital applications. This material is produced from the pyrolysis of plant materials containing carbon and is subjected to activation. A large number of toxic gases can be removed from the air by passing through activated carbon.

 

for example

 

Carbon monoxide is one of the things that can be separated from the air by injecting a series of chemicals (silver, copper and chrome salts) into active carbons. have.
