What You Need To Know About The Processes Of A Biomass Pyrolysis Plant

Pyrolysis is described as a thermal decomposition associated with biomass which occurs in an environment where oxygen is absent. This chemical reaction is a precursor for both gasification and combustion processes that naturally occurs within a few seconds. Products produced through biomass pyrolysis range from bio-oil, to biochar, onto gases that include carbon dioxide, carbon monoxide, hydrogen, and methane. More information on biomass pyrolysis plant here.

Dependent on the actual thermal environment and the highest temperature that is reached, pyrolysis mainly yields biochar at the lower temperatures that are under 450 degrees Celcius. When the heating rates are slower, mainly gases are produced at a higher temperature that exceeds 800 degrees Celcius. At the intermediate temperatures, using a heating rate that is relatively high, the main product that is produced includes bio-oil.

Pyrolysis provides an attractive, cost-effective, and flexible method to convert biomass that is solid into easy to transport and store liquids. The bio-oil produced is used successfully for producing heat, chemicals, and power. The biomass waste that is used in the pyrolysis plants includes a number of organic materials such as coconut shells, rice hull, wood, sawdust and so on.

The different biomass feedstock options are also commonly used in the pyrolysis processes. The process of pyrolysis will depend on moisture levels in the feedstock, which should usually not exceed 10%. The waste streams that contain high moisture levels like sludge or meat-processing wastes will necessitate drying before they can undergo the process of pyrolysis.

The nature and efficiency of pyrolysis processes depend on the feedstock particle sizes. Many of the current pyrolysis technologies are only able to process particles of small sizes (maximum of 2mm) to achieve heat transfer that is rapid through these particles. This often means that the size of the particles need to be reduced before they can undergo the process of pyrolysis. The pyrolysis plants usually adopt crusher or shredder machines to assist with this part of the process.

The process of pyrolysis is categorized as either fast pyrolysis or slow pyrolysis. The fast pyrolysis processes are at this stage the more widely used system. The slow pyrolysis often takes a number of hours in order to complete, and the primary product is biochar. Fast pyrolysis, on the other hand, is a very efficient process that yields 60% bio-oil within a matter of seconds. This process also produces 20% syngas and 20% biochar.

What Is Bio-Oil?

Bio-oil produced from biomass pyrolysis plants is a dark-brown liquid. It features a density that is much higher when compared to woody materials and this assists with lowering transport and storage costs. Bio-oil cannot be used directly in the standard internal-combustion engines. It can, however, undergo an upgrade through a gasification process to produce a syngas which is then converted into bio-diesel, or to produce specialized engine fuels. Bio-oil has become increasingly popular for co-firing as it is easy to handle and burn when compared to solid fuels. It is also a product that is much cheaper to store and transport. In addition, the bio-oils are an important source when it comes to specialty chemicals and different organic compounds. See the blog: http://arriedman.webstarts.com.
