  1. Two-stage acidic-alkaline pretreatment of Miscanthus for bioethanol production

    Pretreatment is the rate-limiting step for bioethanol production from lignocellulosic biomass, and subsequently intensive studies have been undertaken to improve the pretreatment efficiency. However, so far most pretreatment methods failed to achieve desirable sugar recovery from both cellulose and …

  2. Evaluating the potential for improving anaerobic digestion of cellulosic waste via routine bioaugmentation and alkaline pretreatment

    … was routine bioaugmentation and the second was alkaline pretreatment. Both of these methods were applied to a two-phase anaerobic digestion process for treating the residuals from sweet corn processing, which have a significant lignocellulosic fraction as well as some starch from the base of the …

  3. Thermal hydrolysis and thermal alkaline pretreatment of waste activated sludge: comparison of effects on biogas yield, dewaterability, sludge liquor and cost-benefit analysis

    … effect of process conditions (T, pH) of thermal alkaline pretreatment (TAP) and thermal hydrolysis (TH) of waste activated sludge (WAS) on biogas yield increase, dewatering potential of digestate, return load increase and refractory COD using same sludge. Moreover, it was intended to compare …

  4. Concentration and Recovery of Rare Earth Elements from Eastern US Coal Refuse

    … approach that showed the most promise was strong alkaline pretreatment, followed by ion-exchange leaching with ammonium sulfate at pH 4. A combination of strong alkali and high-temperatures treatment successfully liberated the REEs, converting them to a form amenable to ion-exchange leaching. The …

  5. Effect of pretreatment on the breakdown of lignocellulosic matrix in barley straw as feedstock for biofuel production

    … matrix. In this study, two types of biomass pretreatment were applied on barley straw grind: radio-frequency (RF)-based dielectric heating technique using alkaline (NaOH) solution as a catalyst and steam explosion pretreatment at low severity factor. The pretreatment was applied on barley …
