The process equipment and system were devised by the inventor to find the conditions under which this could be done. Unless these were found to be possible it was not necessary to evaluate further on account of the very limited budget available. It would be left for future R&D by others.
Accordingly the R&D was performed and proven successful at Regensburg University in Bavaria under the supervision and instruction of the inventor employing the University staff. Patents were eventually granted, almost four years later thereafter. The experimental results were reported by the University researchers in Regensburg.
The good results obtained were surprisingly good and beyond expectations and not proven before – or the patents would not have been granted as the findings would have been anticipated if they had already been achieved. In all the time since the start of the Second Industrial Revolution and the exploitation and use of fossil-fuels, this had not been established or found. Furthermore both the rates and amounts of conversion of CO2 to CH4 were found to increase exponentially as pressure increased and also accelerate showing the pathway for further tests to find optimum better conditions for even further better development:
The CO2 Recycled Process operates under aqueous liquid high pressure conditions – not gaseous! This enables use of approximately 740x smaller compact plant & equipment and faster reaction kinetics because of closer proximity of reacting components to be used than by gaseous processes. These are great capital cost savers. Various other innovative measures are incorporated in the plant equipment patent to provide further process enhancers and cost savings.
