Rice husk is one of the agro-residues which is available
from mills in relatively dry form . Rice husk has so far been considered as a cheap, abundantly available renewable fuel . But using rice husk to make a valuable product which can be used in many industries has hardly been thought about. Living in a rice producing country, finding that this is a terrible waste of resource ,I determined to do some studies on rice husk . After some years with the indispensable helps of my colleagues and relatives, I found that we can make ACTIVATED CARBON from rice husk . The applies of ACTIVATED CARBON are various ,and the price of ACTIVATED CARBON made from rice husk is very low , compared to other materials. Moreover , from the process of producing ACTIVATED CARBON from RICE HUSK I found that we can also get a very useful sub-product . That's Silicon SiO2. With the purity of 97.3% it can be used in semiconductor industry and many other processes like producing SiC which I also practically produced . |

And here is the process I used : Rice husk--(Pyrolysis)-->Char1--(gasification
with steam)-->Char2- -(treatment with HCl)-->Char3--(Digestion with NaOH)-->Carbon--(activate with steam)-->ACTIVATED CARBON |
