I wish I could be of more help to you.
But I am limited in what I can say about the subject.
I have spent some time with Wayne Keith and his wood-gas vehicle and walked away impressed. The main pitfall I observed with his and other setups is the amount of fiddling needed to get it to run over the large load range a road vehicle operates at. To his credit, he has driven cross country with his contraption, so it is not an impossible pipe dream.
If you are wanting to use only liquid hydrocarbons, that is a good pathway that can yield the CO/H2 gas mix (syngas) that you seek to produce. However, it will still have poor "throttle response" and even with the use of Ni/Fe catalysts, the heat needed for a clean production of syngas will be difficult to keep above the critical reaction level. The need for an electronic feedback circuit would be almost a certainty as the variable fuels would result in a variable carbon to H2O ratio. I am assuming you are building a steam reforming system to fuel your engine.
And please forgive the overzealous denizens of this forum. Many are not scientists, and those who are have very narrow specialties as those of us in the sciences are wont to have. They easily get excited about pie tins and used sign boards and denigrate anyone who wants to do anything mind bending with engines. The few on this forum who do work with engine modifications have often come under duress from experts who have never set foot inside a dyno lab.
Feel free to stick around for a bit. Just ignore the "negative Nancy" crowd of experts and maybe you can get a constructive thread going.
And yes, I have built vapor carbs, GEETS and reformer engines. They all have their positives and their pitfalls. But, when you side step the hocus pocus surrounding them, they all have some good science.
