There are many bio waste available in our day to day life , instead of dumping them, we can make use of that waste matter by extracting oil from such bio wastes by using a setup called “fixed bed reactor” so many research has been made in past on this fixed bed reactor, in which we are conducting experiments on different bio wastes and going to extract oil on that corresponding wastes(dry seeds) with a heating element of 0 to 300?C, here we changed the cooling system and in that oil will be collected from the overflow of the condenser bath.
