Esterification over Acid-Treated Mesoporous Carbon Derived from Petroleum Coke.

ABSTRACT: Multistep activation of a Canadian oilsands petroleum coke that yields an acidified mesoporous carbon catalyst is reported. Microporous-activated carbon (APC; ∼2000 m²/g), obtained by thermochemical activation of petroleum coke using KOH, was impregnated with ammonium heptamolybdate and activated by carbothermal hydrogen reduction (CHR). The resulting Mo₂C, supported on high-mesopore volume (V _meso ∼0.4 cm³/g) carbon, yields the desired mesoporous carbon catalyst (V _meso ∼0.7 cm³/g) following acid washing. The effect of CHR temperature and the benefit of Mo₂C loading on mesopore development is reported, and pore development models are discussed. The mesoporous carbons are active for the esterificatio
