Through waste pyrolysis, waste tyre, rubber, oil sludge or plastic can be converted to pyrolysis oil and carbon black which has high economic value in our daily life. As plasma pyrolysis is currently a new ray of hope for us for plastic and bio-medical waste treatment. 5.1 Biomass Pyrolysis. The former issue is a feature of pyrolysis processing (and also a The description of this method, along its advantages and disadvantages are presented in this chapter. However, disadvantages of this pyrolysis technology include slow process, low energy yield and excessive energy consumption [8] [9] [10]. Pyrolysis is the thermal decomposition of an organic material under starved-air or oxygen-deficient conditions. Pyrolysis can be obtained through thermal or catalytic pathways. 1 Chapter 1: Introduction Fossil fuel consumption has increased over the past century, becoming a primary source of energy for many countries around the world and accounting for . Ultrasonic Spray Pyrolysis. Gasification of Municipal Wastes. The particle material of process (also named as precursor) usually has a high evaporation temperature. Advantages of using pyrolysis technology to convert plastic to oil: 1. The valuable derivatives of crude oil obtained through pyrolysis of non-recyclable waste reduces the need to excavate fossil fuels form the earth. Study now. - No high temperatures are required during processing (up to 500 C). inert atmosphere. Pyrolysis seems to be the optimal thermochemical treatment option compared to incineration and gasification. . The energy demands for heating, melting, pyrolysis, and evaporation determined in the pyrolysis experiments were normalized using the feedstock lower calorific value. While a stationary pyrolysis plant is a more durable, mobile units are still expensive. Preceramic polymers (polymer precursors) are the Polymers, which can be converted into Ceramics by pyrolysis. Companies have been experimenting with these technologies for over three decades. The main disadvantage of pyrolysis technology is reflected by the waste pyrolysis plant. The first disadvantage is the high temperature supply. - Substrates with complex geometries can be coated. Rapid/Fast Pyrolysis : Primarily to produce Bio-Oil and Gas -Biomass is very rapidly heated (~1000-10,000 ⁰C/s) to a temperature around 650 ⁰C-1,000 ⁰C depending if bio-oil or gas products are desired. This means that it is only viable for companies that have large amounts of waste they can convert into biofuel. The methods of sludge treatment include: healthy landfill, incineration, .

It takes a substantial amount of cash to start a mobile pyrolysis plant, but the advantages are more than worth it. Under the enough heat and oxygen, an explosion may occur. Pyrolysis occurs when solid organic matter is heated, resulting in the release of gases, oils, and char, hence the word's etymological root of "loosening or change by fire". The surface is heated by hot flue gas produced by combustion of pyrolysis gases or char and rotates while biomass is pressed onto the hot surface (873K). and easy to operate; they function at a lower process temperature as well (400 °C). Beston Machinery has developed the latest waste plastic pyrolysis plant, which is aimed at converting waste plastics into fuel oil and carbon black. The key advantages of pyrolysis. all the organic and pathogen in the sludge will be destroyed through the oxidation and pyrolysis with the temperature of 850 to 1100 degree centigrade.
