conversion of HC to methane
conversion of HC to methane
(OP)
Dear all,
I am writing to ask whether anyone knows how to convert HC to methane.
Actually, I have a stream with CH4 (86%) plus higher HC (14%) and just traces of CO2. The goal is to increase the CH4 content up to 97% reducing the concentration of the other HCs.
As far as I know the pre-reforming stage used for the syngas production can do this job with an highly active Ni catalyst but I am still uncertain about the feasibility of such a process. So, if anyone can help me I would be greatful.
Cheers-Gianluca

there are hundreds of gas processing facilities that use the cryogenic process (turbo-expander) for removing heavier hydrocarbons; thus generating revenue for both products (i.e. heavier hydrocarbons + pipeline quality gas).
a simple preliminary design analysis can be accomplished by knowing the inlet gas composition, pressure, & temps and determining the outlet conditions. be glad to recommend a reputable process design company (EPC firm) upon request.
meanwhile, good luck!

Anyway now I am working on a different solution, it is the employment of the pre-reforming step used to produce syngas. It allows me to get 95% methane in the product gas which suits my requirements (93%) and I do not need any H2 in the inlet stream. However if I would use H2 I could get a concentration above 99%. I will let you have more info next week cause I am waiting for details from the catalyst supplier.
