i am new to the biogas process,i have rudimentary knowledge,but i understand the process,biogas contains;O (0-2%),CO2(30-40%),N(1-2%),H(5-10%),H2S(trace),CH4(50-70%),H2O vapour,in processing a molecular sieve(3A) could be used to filter the gas stream leaving CH4,H2S and H2O,which then could be ''scrubbed'' with activated carbon,leaving CH4 and H2O to be stored and used as fuel,from the molecular sieve the combined O,CO2,N,H could be water scrubbed to remove CO2,my question is this,could the O,N,H also be burned as fuel?any help is appreciated,thanks
