What is Proliz?

One of the thermo chemical processes is prolysis. Prolysis occurs when plants are exposed to hot environments without air. The formation of energy sources such as petrol, coal, natural gas, charcoal is actually a type of prolysis.

Prolysis is the name of the thermo-chemical process in which organic substances undergo thermal breakdown at high temperature and in an oxygen-free environment, consisting of the Greek words ‘pyro’ meaning heat and ‘lyse’ meaning to disintegrate. At the end of the process, the fixed carbon and

 in organic substances are separated. The volatile is then condensed to produce two different fuels in liquid and gaseous form. Prolysis volatile is roughly the transformation of large molecules into smaller gas, liquid and solid molecules. Prolysis occurs when plants are exposed to hot environments without air. The formation of energy sources such as petrol, coal, natural gas, charcoal is actually a type of prolysis.

Prolysis process and its types

During prolysis, the chemical bonds of the biomass subjected to prolysis are thermally degraded in the absence of oxygen and at high temperature. Large hydrocarbon molecules are broken down or organised into simpler molecules. In general, the temperature is 400-600 'C and the pressure is atmospheric pressure.

 Solid, liquid and gaseous products are obtained by prolysis. The type and quantity of products depends on factors such as the type of biomass, heating rate and final temperature. Prolysis is divided into five basic groups as slow, moderate, medium, fast and flash according to the time and temperature parameters applied during the process.

Usage areas of Proliz products and their contribution to the economy;

The most well-known prolysis process is the production of charcoal (biochar) by slow prolysis. It is also known as degasification and the solid product is the target product. Generally, stacked wood piles are covered with soil and carbonization of wood pieces is achieved by combustion in a limited air environment. The gases produced during charcoal production are vented to the atmosphere. However, if they are condensed and collected, a liquid product consisting of a mixture of organic chemicals and water with a lower average molecular weight than wood is obtained. There are also non-condensable gaseous products, including gases such as CO2, CH4, CO, H2, N2.

Charcoal production, especially from oak trees, is quite common and is mostly produced by classical methods in Turkey. For this purpose, torches are set up with properly stacked woods and the woods are covered with soil and carbonized by partial combustion. The oil from prolysis is used as fuel in the glass industry, tire industry and cement industry. It is also converted into electrical energy by engines and generators running on heavy fuel oil. Non-condensable gases (CH4, H2, CO, CO2) are used as heating fuel in the prolysis system. In addition, electricity is generated from the surplus.

Contribution of prolysis product (biochar) to agriculture and animal husbandry

AGRICULTURE: If biochar is given to plants together with fertilizer, the water retention properties of biochar are revealed here. Therefore, it will be enough to water the plants, which are watered every day, once a week due to fertilization with biochar. Plants will develop more healthily as they receive water little by little and there will be a 25% yield increase.

LIVESTOCK: If biochar produced from oak and hornbeam wood is added to animal feed and silage , it absorbs the gases in the animal's stomach and the animal relaxes. Meat and milk yield increases by 25-30% When added to cat and dog food, it removes the odor of feces. is a must-use product for pets.
