Thank you all for sharing your expertise on this matter. I should make it clear that due to the historic nature of the ship, and the way its restoration is to be funded, the design criteria are limited to having to stick with about half the propulsion power originating from steam in essence...

A project has been funded to rescue a somewhat dilapidated mid-60s ship (once a car ferry) now 'sunk' (only in about six foot of water) at the North-east of England port. The main points of the power engineering are that the ship is to remain at least part 'steam' but refitted to 21st century...

Thanks again for all the feedback and advice on this design, and thanks for being so constructive in the tone also. But now I've got a nagging feeling that, having explained my design more or less in full, the unspoken consensus out there is this is, well, 'out there'! So, as a final ask: Is...

Thank you -IvyMike- for expanding the my description; making it more legible in the process (I tried to sum-up all three ccts in on paragraph). GregLocock asks "Now you've got hot liquid carcinogenic acidic water what are you going to do with it? Inquiring minds are interested." Earlier I...

Thanks; although weight and bulk are still a seriously major hurdle, this appears to be a design that could actually be built and integrated with a larger IC-engined vehicle, lorries/artics, buses, etc. Getting something over two-thirds of the condensible liquids recovered would appear to make...

Re - closed-circuit exhaust gas cooler: Yes. I had wondered if an approach along those sort of lines was possible, but decided it must go against the laws of thermodynamics (, or something!). Now I'm not so sure... So the exhaust temp after the manifold would initially drop as it transferred...

Thanks both. Maybe there is a material that can act as a Molecular Sieve but can survive slightly higher temperatures. Cooling the inlet air with evap. cooling could be a means to control the exhaust temps, but this would cause atomisation problems (unless we switch to gas fuels, propane, etc =...

Thanks for all the responses. And "D'oh" on the atomic weight of H20! Thanks -ivymike- for translating my gibberish to mean 'molecular sieve'. And thinking of 'Gore-Tex'. Thanks also -140Airpower-. Re: - "About Gore-Tex, the molecular sieve principle will work with high temperature materials...

Cyclonic separators can be used to collect water in after-treatment when hydrocarbons are burnt, but (for one thing) this expends energy in cooling the walls of the cyclone. Is there a means to, say, use a similar effect of centrifugal force to concentrate the water molecules near the outer...

Thanks for the replies. I have looked up most of the areas that have been mentioned above previous to posting here. I think one of the silly mistakes on my pat was when I had been looking up water-gas online I was also getting back info on water-gas shift & this was confusing my amateur...

Thanks moltenmetal for your helpful response. Indeed, I had expected the proportion of inorganics in charcoal to be down to an ignorable percentage. I may consider whether a non-catalyst route should be taken, once I have a better grip of the chemistry. Or alternatively consider how efficient...

How about with charcoal?

I know superheated steam will be reduced with amorphous carbon to create syngas. Where can I find details of the reaction conditions? I ideally want to know what the lowest temperature this reaction will take place (in the presence of a catalyst if necessary) at or near ambient pressures. Also...
