We produced liquid fuel after condensation of gas which come from the waste plastic bags by heating them at 500 degree centigrades in enclosed furnace in absence of air. Now we are confused about the distillation of the liquid fuel. One more thing is also confusing me that If we stored condensed liquid fuel in the plastic bottles than vapours are shown inside surface of bottle but if we poured it in the glass bottle, than there is no vapour inside. So is this fuel is reactive to plastic? or what? please help!
