The carbon content of pyrolysed
(bio)char fluctuates between [+ or -] 5% and 95% of the dry mass, dependent on the feedstock and process temperature used.
Kerogen is considerably pyrolysed
While inorganic materials are converted into vitrified mass, organic materials could be pyrolysed
or converted into gases like hydrogen, carbon monoxide and other lower hydrocarbon gases.
Generally, higher PAH concentrations have been found in biochars pyrolysed
for shorter times and at lower temperatures (350-500[degrees]C) (Hale et al.
Briefly, dried sediments were first pyrolysed
at 450[degrees]C during 24 hours to mineralise phosphorus bound to organic matter.
The model distinguishes into an unreacted core and an inert outer layer of pyrolysed
Observing the surface are that has pyrolysed
, it can be seen that after time 230 seconds, the surface area begins to decay, which indicates that the fire will self-extinguish soon after that.
2010) examined changes in the properties of waste pine and eucalyptus bark treated with alkaline tannery waste (at 2 different concentrations) and subsequently pyrolysed
Effects of pyrolysed
aeroengine oil on human health Germany's pilot and cabin crews trade unions and associations are calling on the German government to launch an independent inquiry into the effects of pyrolysed
aeroengine oil on human health.
They can further be pyrolysed
in an inert atmosphere at temperatures around 1000[degrees]C to obtain carbon aerogels.
150/[micro]g) were placed in quartz tubes and then pyrolysed
at 610[degrees]C in a flow of helium for 10 s in a platinum coil using a CDS 1000 pyroprobe (Chemical Data System, Oxford, PA, USA) interfaced to a Perkin Elmer Turbomass Gold equipped with a fused silica capillary column (Chrompack; CP-Sil 5CB; 50m x 0.
by plasma burner into the pyrolysed
material, maintenance of required temperature by electrical heating elements, short residence time of vapor in the reaction zone and fast cooling of the product.
