Articles: Understanding Gasification and
Pyrolysis
"A great
way to learn more about a subject is to read information from a number of
sources".
You can learn a lot by reading around a
subject like gasification and pyrolysis, so we will scour the web for you and we will publish the best
articles written about Advanced Thermal Treatment.

Plasma gasification is an excellent way of recycling garbage. The facilities are large and expensive but the by-products from the process are carbon dioxide, nitrogen, water vapor and inert slag making it very environmentally friendly.
Gasification plant technology is at the forefront of developing alternatives for conventional furnaces. Pyrolysis is a similar renewable energy technology. All use biomass and usually use waste biomass. Continue...
IGCC - Integrated Gasification Combined Cycle technology - the big new hope in clean and sustainable solid carbonaceous fuel burning to replace Coal Fired Power Stations - revealed in this article.
No site on gasification would be complete without including information about GE's Gasification process skills, and their leading role in developing the IGCC Gasification Process (IGCC). So, here it is! Oh, and Don't forget to watch the embedded video!
The Pyrolysis of Automotive Shredder Residue: Four pyrolysis processtechnoogies are reported to be semi or fully commercial, and clearly specify that they can handle ASR as a feed.
Oil refinery gasification is a new use for gasification technology. The refinery industry is a highly competitive global industrial sector where sales are governed largely by price. For individual refineries to survive they must develop and evolve to meet changing quantity and quality requirements for the domestic fuel market.
What is Pyrolysis?
Pyrolysis is a process which is designed to produce a char which can be processed into a
liquid with a heat value in the range of 50-80% of mineral fuel oil.
The oil which pyrolysis produces a is called bio-oil, which is the basis of several processes for the
development of fuels, chemicals and materials. There are various concepts around which pyrolysis is being
devemoped. One concept is to use the residual fractions of the oil for hydrogen production after co-products have
been separated making pyrolysis a possible component of a future hydrogen fuel based economy.
Pyrolysis produces energy fuels with high fuel-to-feed ratios, making it the most efficient process for biomass
conversion, and the method most capable of competing and eventually replacing non-renewable fossil fuel
resources.

So pyrolysis produces bio-oil, char, and synthetic gas from biomass. One company has developed what it
calls "Fast pyrolysis" which operates at higher temperatures and over shorter time periods than other
pyrolysis processes. They say that this converts more of the biomass into gas and oil, and less into charcoal. Fast
pyrolysis is aimed at producing liquids for the direct application of heat and power in bio-refineries with typical
applications of pre-conditioning of gasifier feedstock –producing liquids and gases as well as char and even
slurry.
However, we are told that the fast pyrolysis of non-woody feedstocks can lead to the production of highly
reactive liquids and can be rich in high tars with some product sbituminous in character and solid at room
temperature leading to storage and processing issues.
Carbonscape would not initially be producing charcoal for biochar, but for industrial uses
of charcoal, as a substitute for coal, because prices are rising internationally. Carbon credits will be earned for
the treatment of wood waste into charcoal. Carbon dioxide produced in the biomass gasification step is constantly
recycled into the reactor, thus eliminating the release of carbon dioxide into the atmosphere. It must be noted,
however, that the paper sets forth only a conceptual framework.
Biochar is charcoal formed by low temperature pyrolysis. Higher temperature pyrolysis produces a more
traditional charcoal. Biochar is charcoal formed by low temperature pyrolysis. Medium temperature pyrolysis
produces a more traditional charcoal, high temperature pyrolysis produces activated charcoal.

Capture.
