Hello guys I have a q, i have been reading all the posts about the problems with energy transfer, core melts and so on . Why not embed the nickel / catalyst mix in a honeycomb, or other structure that gets easy acess for both H2 and heat trasnfer to the walls of the tube ? Is there any

There are a number of options. Google porous nickel or nickel foam but beware of Alibaba. INCOFOAM is an available nickel foam, produced in a wide porosity range which has been available for several years. A large scale commercial production facility is operating at the Vale/Inco refinery near

Marten, You might want to google or bing nickel nanowire grow or nickel whisker grow. Some of these techiques are hazardous, so better use extreme caution. My guess is that (poly-)crystalline nanostructures are most promising. Hello guys I have a q, i have been reading all the posts about

I think are a many potential downsides to using bulk material substrates (foams, foils, wires) with nickel coatings. - you might get large and non-homogenous transient temperature changes throughout the reactor and this could lead to deformation and even breakup of large continuous scaffolds. - it

If I was attempting to build a system from scratch, I would be tempted to stick as close as possible to what we know of the standard receipes used by others. The problem is that at the moment we don't understand the system to know what is important and what is not. My brother helped build a
