I am currently doing a design project concerning pyrolysis and gasification of biomass to get hydrogen, but in the process of getting hydrogen CO2 and N2 will be given off, I am trying to find a way to separate them or make them useful so that the whole process would be carbon neutral. Please does anyone have any ideas?
You can find the following for N2,

Hi Harry,
The article in this link discusses copolymers with good carbon dioxide/nitrogen separation performance

Hope it helps.
You may also want to try pressure swing adsorption
Article Carbon Dioxide Nitrogen Separation Through Pressure Swing Adsorption
The issue of separating co3 and n2 from a mixture of gases is handled in the simplest possible way by using PSA- pressure swing adsorption process indicated already. There is no great research involved. But some development in terms of the choice of the zeolite material and trials on a system that can be ordered. I think that is all there is to it.
Shekinah Harry. Like mentioned earlier by our fellow researchers, pressure swing adsorption can be one of the best processes to separate these gases. Also, the high pressure separation of carbon dioxide/nitrogen or if it is the mixture of carbon dioxide/hydrogen, both can be separated by the application carbon bead samples. High-pressure volumetric apparatuses can be used by the application of high incremental pressure of gases of interest. Adsorption of the gases as a function of the increasing equilibrium pressure can be evaluated on the surface of the activated carbon beads. To make it more clearer, here is the link of one of the paper that can answer your question...
Again, good question..!

The Benfield/Catacarb process (same process with 2 different names) is a proven way to remove all/most CO2 from a gas mixture
