Process and system for production of synthesis gas

A gasifier system comprising:

• i) a pyrolysis chamber configured to be operated within a desired elevated pressure range and within a desired elevated temperature range;
• ii) at least one mechanically propelled rotating carousel platform configured for the decomposition of carbonaceous materials by pyrolysis and at least one mechanically propelled rotating carousel platform configured for the steam reformation of said pyrolytically decomposed carbonaceous materials positioned within the pyrolysis chamber and configured to be operated within substantially the same pressure range as the pyrolysis chamber;
• the pyrolysis chamber being mounted in a spaced apart relationship from a thermal circumscribing heat shield encasement, said spaced apart relationship defining a space between the pyrolysis chamber and the thermal circumscribing heat shield encasement;
• the pyrolysis chamber being configured for mixing and advancing a carbonaceous material disposed therein;
• and
• iii) a heating system configured to heat the space and the pyrolysis chamber, while maintaining a cool exterior to the thermal circumscribing heat shield encasement.
