This method
produces pyrolysis oil, or bio oil.

A third route, known as
pyrolysis, heats dried and ground biomass to about 550 ˚C in an oxygen - depleted chamber (so the biomass doesn't burn),
producing a mixture of gases, liquids, and a gray, carbon - rich solid called coke.
The zeolite catalyst then converts these hydrogenated products into light olefins and aromatic hydrocarbons in a yield as much as three times higher than that
produced with the pure
pyrolysis oil.
The hydroprocessing increases the intrinsic hydrogen content of the
pyrolysis oil,
producing polyols and alcohols.
Pyrolysis bio-oil is
produced by rapidly heating the forest residues in an oxygen - free environment and then rapidly cooling the products formed.
«During
pyrolysis the biomass is degraded and the compounds
produced can be rapidly extracted, because if not «they start to react among themselves and
produce things we are not interested in.
The process to
produce bio-oils is based on flash
pyrolysis.
This project is particularly efficient in the treatment of tires: «When flash
pyrolysis is carried out under specific conditions, we can
produce some very interesting raw materials, like carbon black.»
This researcher has developed a reactor based on conical spouted beds which, by means of flash or rapid
pyrolysis,
produces fuels and raw materials using various types of waste.
A team at Zhejiang University, China, has developed a novel cracking technology for the upgrading of bio-oil,
produced by the fast
pyrolysis of biomass, to biogasoline.
I generally find lye + heat effective, though some think
pyrolysis more economically efficient than saponification, as it sequesters the carbon and
produces both fertilizer and low CO2E - intensity fuels, whereas the former only leads to soap and ashes.
Fast
pyrolysis is rapidly heating biomass (including corn stalks) without oxygen to
produce liquid bio-oil, which can be upgraded to transportation fuels.
Two kinds of BC are
produced in combustion processes through different formation pathways: char is an impure form of graphitic carbon from combustion residue formed directly by
pyrolysis in smoldering fires, while soot is a combustion condensate
produced by gas - to - particle conversion at relatively high temperatures (> 600 °C) in flame.
This process, called
pyrolysis, also
produces syngas and bio-oil that can be used as a renewable fuel.
Just to make sure we're on the same page,
pyrolysis is not the burning of plastic... but, as GAIA pointed out repeatedly during the chat, the synthetic oil
produced is burned.
Biochar can be
produced by
pyrolysis at around 500 degrees C, either slowly (over days, the traditional approach e.g. in kilns), which results in about equal amounts of biochar (about 35 % of the original biomass), liquid and gaseous fuels; or rapidly (e.g. flash
pyrolysis, in seconds), which gives less biochar (about 15 % converted) less gaseous products, but more liquid «bio-oil» products (about 75 %).
Biochar is
produced through the «slow cooking» (
pyrolysis) of plant wastes.
«What we're looking at is
producing those kinds of charcoals in a modern
pyrolysis reactor,» notes Brown, who received a $ 1.8 million grant from the U.S. Department of Agriculture (USDA) to attempt to recreate terra preta using corn stalks.
