焦炭的形成是醋酸蒸汽重整过程中面临的较大挑战之一。从表1中我们可以看到

Coke formation is one of the great challenges acetate faced steam reforming process. We can see from Table 1, both CO disproportionation, decomposition, acid decomposition of CH4, or condensation of acetone can cause coke formation [52]. CO at all temperatures typical for the reforming of acetic acid, may by "Boudouard" disproportionation reaction, and deposition of carbon. Thermal decomposition of CH4 in the main relatively high temperature (> 600 ° C) to make a contribution to the formation of coke. Acetone and acetic acid may also be formed in the pyrolysis coke. Meanwhile, the acid catalyst surface irreversible decomposition or dissociation of carbon deposited as coke precursors, such as ethylene, polymerization of these intermediates would result. Acetone and ketones are formed mainly in the lower reaction temperatures (

The formation of coke is one of the great challenges in the process of steam recombination of acetic acid. From Table 1, we can see that whether it is the disamification of CO, the decomposition of CH4, the decomposition of acetic acid, or the reduction of acetone, it will lead to the formation of coke. Coos can be disambiguated through the "Boudouard" reaction at all typical temperatures used for acetic acid recombination, promoting carbon deposition. The thermal decomposition of CH4 mainly contributes to the formation of coke at a higher temperature (-600 degrees C). Acetic acid and acetone can also be heat-desdone to form coke. At the same time, acetic acid on the surface of the catalyst irreversibly decomposed or dissofarted into coke precursors, such as ethylene, the polymerization of these intermediates will lead to carbon deposition. The formation of acetone and ketones occurs mainly at lower reaction temperatures (

The formation of coke is one of the major challenges in the steam reforming of acetic acid. From table 1, we can see that no matter the disproportionation of CO, the decomposition of CH4, the decomposition of acetic acid or the condensation of acetone will lead to the formation of coke [52]. At all typical temperatures for acetic acid reforming, CO may be disproportionated by "boudouard" reaction, which promotes the deposition of carbon. The thermal decomposition of CH4 mainly contributes to the formation of coke at higher temperature (> 600 ° C). Acetic acid and acetone can also be pyrolyzed to form coke. At the same time, the irreversible decomposition or dissociation of acetic acid on the catalyst surface is coke precursor, such as ethylene. The polymerization of these intermediates will lead to carbon deposition. The formation of acetone and ketone mainly occurs at lower reaction temperature（
