Catalytic Hydrogenation of Corn Stalk to Ethylene Glycol and 1,2-Propylene Glycol

Abstract: The use of whole lignocellulosic biomass as the feedstock for cellulose conversion is of great significance for largescale, low-cost biomass conversion to biofuel and other useful chemicals. We recently achieved the direct conversion of cellulose (pure microcrystalline cellulose) into ethylene glycol at high yields over tungsten carbide catalysts. Here, corn stalk, an agricultural residue available in large quantities, was used as a lignocellulosic feedstock for conversion over nickel-promoted tungsten carbide… Show more

“…The cost of catalysts was greatly reduced due to the convenience in the preparation and the better reusability of catalysts without decay in the performance [28,115]. The feedstock involved microcrystalline cellulose and raw biomass, in detail including corn stover [22], birch wood [24], miscanthus [119], concentrated glucose [116,120], and Jerusalem artichoke [121]. The product distributions were tuned between EG, erythritol, and hexitols by varying the ratio of tungsten and hydrogenation metals [88].…”

“…On the other hand, it guarantees easy separation and recovery of tungsten acid. Taking into account that raw biomass, if properly pretreated, 10 can be well converted into EG with such a tungsten-based catalyst, it can be expected that the combination of tungsten acid and Ru/AC will constitute a promising candidate for the future commercialization of the one-pot conversion of biomass to EG due to its high efficiency, low cost, and exceptional reusability.…”

“…Among others, the one-pot conversion of cellulose to ethylene glycol (EG) has been paid considerable attention as this unique transformation leads to a high yield of EG (up to 75 wt%) which is commercially attractive. Since the first report of this reaction in 2008 [5], Zhang and coworkers have made systematic studies on the catalysts development [6][7][8], optimization of pretreatment and reaction conditions [9,10], reaction kinetics [11,12], and mechanism understanding [13,14]. For example, following the development of Nipromoted tungsten carbide, they further explored three-dimensional carbon supported tungsten carbide catalyst which afforded EG yield as high as 73% even without the promotion of Ni [6,7].…”
