this is very old technology route, and is normally also integrated with a heavy organics section . so there are uses for the scrubbed gasses .
some are quite nasty some are beneficial.
liquid CO + liquid H2 is the route to Mustard Gas.
Mustard gas ( Non sadam hussein use) is the building brick for di-isocyanites , instant adhesives and the polymerisation agents for plastics ,
I suspect the greenest use of CO2 would be to fix the gas in precipitated calcium carbonate, by the adsorbtion route into calcium hydroxide solution.
couldn't claim as carbon neutral but it would deal with a lot of the CO2 from the gasification proces. and it would be in solid phase and it would be added to cement/mortars and concretes, which would continue to adsorb CO2 from the atmosphere as it slowly cured over hundreds of years.
