The goal of gasification/ steam reformation is the complete transformation of feedstock carbon content into gases (syngas) with high heating values. The Boudouard reaction is a very important process to achieve this goal by transforming solid residue carbon content and non-combustible carbon dioxide into a usable gas - carbon monoxide and increasing the heating value of the produced syngas.
Sure, a catalist can be found for producing CO as a fuel. The problem is that the syntesis of CO should take less energy than energy released upon burning CO.
Experiments have been done to prevent carbon attack in refractories, caused by the Carbon deposition from CO containing gas. This was done successful by minimising the catalytic components in the refractories. Since catalysts work "both ways" in the reaction it is likely that also the formation of CO from carbon will be propagated by these catalysts.
Usually carbon exist in graphite form with some defects, and it is this defect that facilitates the boudouard reaction. As a consequence, catalysts that can make defective points in the graphite structure enhances the reaction. Charcoal is one of the most reactive carbon material, and we can use it for the low tmeperature conversion of CO2.
Intercalation compounds could be the way. They can modify strongly graphite introducing "defective" points. Open to discuss.
It seems to me that the generation of the intercalation compound include the modication of the graphite structure. If it is so, how the intercalation compounds are created should also be considered.
