Hydrogen generation by steam reforming (Mahler AGS GmbH) 

Thank you very much for your question. You are correct. It is very important for the environment and our customers to reduce the NOx(:= oxides of nitrogen)-emission to the lowest possible value. Therefore we are only using “Low-NOx-Burners” which have been developed exactly for following task: controlled combustion of natural gas/process gas with ambient air. But also Mahler AGS’ whole burner system consisting of multiple control loops (e.g. temperature control, ratio-adjustment…) has been optimized for efficiency and lowest emission of NOx. Due to this technology no further treatment of the flue gas for the removal of NOx is necessary.

In principle it is possible to extract the CO2 produced within this process and to reuse it for other purposes and processes. An additional process step and thus additional equipment is necessary in order to purify the CO2. Mahler AGS is also developing and investigating different solutions for the CO2-reuse (e.g. power to chemicals or power to SNG approaches) in order to be able to offer such solutions to the industry.

Matthew Knobel The problem with transformation to bio diesel is the transesterification process which produces CO2 in itself, if we manage the recycling of CO2 will be a great process. Mohammed.teleb@enervail.com

imo can an algae farm consume all the co2 timely from the steam reforming plant? I am not sure...

I'm not sure if it is more efficient to produce hydrogen directly from sun using solar thermal or PV rather than using a but surely it worth to investigate :)

or you can just use it and some more of that steam to make methane and thus more hydrogen

It should be nickel, my final project at university using nickel catalyst for steam reforming

Will the reaction be affected if you use another type of metal?

This is just the flow direction. The tubes are flown through from top to botttom. This is unrelated to the mass of the components.

Thank you for your reply. Indeed, it seems like an error in the animation.

Typically it's several tubes placed in a heated furnace. The reaction takes place within the tubes.

The purpose of steam in the steam reforming process is to provide oxygen for oxydation of the methane and hydrogen for the hydrogen formation. E.g. CH4 + 2H2O CO2 + 4H2. You will find several related chemical equilibrium equations online.
