Abstract
We have been carrying out many kinds of research on bio-char for about 10 years.
At first, we studied biomass pyrolysis technologies and their use.
We found that chars from
sewage and cattle manure contain phosphorous and potassium respectively as citric type
which are easily absorbed by crop.
And it is possible to reduce the application amount of
chemical fertilizer.
Simultaneously, a pilot-scale pyrolysis instrument was made which
facilitates activation, temperature control and singas recycling.
It attributes lower
maintenance cost and environmental friendly.
High absorbent function-char from sewage
sludge was manufactured.
It has an excellent absorption function o
