Problem is
Gassifying coal, produces coke - carbon + mineral content - it is not
the same as charcoal - especially from a soil perspective. In fact it
can be quite toxic. (As a young boy - if we couldn't get galena (PbS)
crystals (to function as rectifying diodes in crystal sets) we used coke
(which was everywhere in the 50's) - which worked quite well - go figger....

Dear Mr. Jain,
What is the maximum tolerable limit of ash in the coal to be used in
your gasifier?There exists a vast potential for making charcoal from
agricultural waste, but the ash content is rather high (between 30
and 35%) in this charcoal because of the high silica content in the
waste.
