  • Coupled Pretreatment with Liquid Nitrogen and Ball

    2019-7-8 · A key problem in the conversion of cellulose into chemicals and fuels is the low product yield from cellulose due to its robust structure. In this work, for the first time, cellulose was pretreated with coupling of liquid nitrogen and ball milling (LN–BM) for cellulose hydrolysis. After the LN–BM treatment, the glucose yield from cellulose by HCl in water increased by almost 2

  • Coupled Pretreatment with Liquid Nitrogen and Ball

    2019-7-8 · Typically, 2 g of cellulose was added to a stainless steel pot (50 mL) along with 15 zirconium oxide balls (diameter of 8.50 mm). Then, 30 mL of liquid nitrogen was poured into the pot. After the evaporation of liquid nitrogen, the pot was immediately placed in a planetary ball miller (Retsch PM100, Germany).
