pürolüüsigaas

Pürolüüsigaas, also known as pyrolysis gas or syngas, is a gaseous fuel produced through the thermochemical decomposition of organic materials in the absence of oxygen. This process, known as pyrolysis, involves heating the feedstock to high temperatures, typically between 400 and 800 degrees Celsius, which breaks down the complex organic molecules into simpler gaseous components. The primary constituents of pürolüüsigaas are hydrogen (H2), carbon monoxide (CO), methane (CH4), and smaller amounts of other hydrocarbons, along with nitrogen (N2) and carbon dioxide (CO2) depending on the feedstock and process conditions.

The composition and calorific value of pürolüüsigaas can vary significantly based on the type of biomass or waste material used as feedstock, as well as the specific pyrolysis parameters such as temperature, heating rate, and residence time. Common feedstocks include wood, agricultural residues, municipal solid waste, and plastics. The produced gas is a versatile energy carrier and can be utilized in several ways. It can be combusted directly in engines or turbines to generate electricity and heat, or it can be cleaned and upgraded for use as a synthesis gas in chemical processes to produce liquid fuels or other valuable chemicals. Additionally, pürolüüsigaas can be a component in the production of biochar, a solid residue from the pyrolysis process. The development and optimization of pyrolysis technologies aim to efficiently convert a wide range of organic materials into a usable and sustainable energy source, contributing to waste management and renewable energy goals.
