You rely on Graphite from cracking for power. You run low on power. Refineries slow down. Cracking stops. No Graphite. Total blackout. Solution: Never put all your eggs in the cracking basket. Keep a separate coal mining operation for emergency power, or use Wind/Solar to cover your refinery base load.
Proliferating the Hydrogen input is useless because you get the Hydrogen back. Only spray the Refined Oil. x ray cracking dyson sphere program
This process creates a self-sustaining loop where the Hydrogen produced can be fed back into the refinery to keep the reaction going, making it a "catalytic" process. Why Use X-Ray Cracking? You rely on Graphite from cracking for power
