1 Coal to 1 Graphite 600/min (300/min) with (without) Proliferator
Use one coal to make one graphite by using X-ray Cracking + Reforming Refine.
Initialization (first time only): 0: fill up the proliferator (if needed) 1, (fully) fill up the belts for hydrogen and refined oil 2, (at the Red Cross Mark) break the belts for hydrogen and refined oil 3, start supplying coal
ps, rough estimation:
Smelter: 600 graphite = 1200 coal 600 graphite = ~1020 coal (mk.3 proliferator, fire ice used), consumption ~15% off
Cracking + Reforming: 600 graphite = ~860 coal (with mk.3 proliferator, fire ice used), consumption ~28% off 600 graphite = 600 coal (without proliferator), consumption 50% off
