Abstract
The invention discloses a new making method of CO clean fuel gas catalyzed by carbonate salt mineral and carbon, which comprises the following steps: adopting carbonate as raw material; grinding carbon and catalyst; blending; making the reacting material; transmitting into reactor or reacting furnace; insulating air; heating; catalyzing; gasifying; guiding the gasified material; purifying; reserving; liquefying; draining the slag as cement slurry or architectural material or metallurgy and fuel purifier; using residual heat to heat air and raw material.
Description
Technical field:
