Red mud (RM) as large quantity of industrial wastes could serve as a low-cost catalyst for catalytic upgrading of coal pyrolysis volatiles. However, the catalytic performance of raw RM for improving the quality of tar was limited because of its composition and structure. In this paper, the RM-based catalyst (RMC) for coal pyrolysis was prepared by ...
An efficient hybrid pretreatment method was developed for butanol production from corn stover using dilute sulfuric acid (DA) and aqueous ammonia (AA). With the optimized AA concentration, treatment temperature and time of 10% AA, 80 degrees C and 24 h, the hybrid pretreatment could effectively dissolve hemicellulose and lignin with solid recovery ...

The hydrolysis of magnesium chloride hexahydrate and the countermeasures against hydrolysis were investigated. X-ray diffraction, TG-DSC analysis, and chemical analysis were employed to characterize the hydrolysis process, and then the hydrolysis reactions occurred at different temperatures were determined. After that, the combination of inhibition...
This study was aimed at screening acidic (HCl, HNO3, and H2SO4) and alkaline (NaOH, KOH and Ca(OH)(2)) pretreatments for the biorefining settings (enzymatic hydrolysis and furan production routes) of walnut shell (WS) and corn stover (CS) using two way heterogeneity (biomass vs pretreatment reagents). Both the substrates were pretreated at constant...
Ni-La-Si mixed oxides with different La loadings were first synthesized through one-step polyethylene glycol-assisted hydrolysis of tetraethoxysilane and inorganic salts in a water-ethylene glycol solution of nitric acid. The Ni-La-Si materials exhibited mesoporous structures with narrow pore size distributions and large specific surface areas. Eff...
