Characterization of Pretreatment for Barley straw by Alkaline Solutions

Enhanced Surface Wettability of Rice Straw with Alkaline Pretreatment

To improve the surface wetting properties of rice straw, effects of distilled water and four alkali pretreatment on the straw surface wettability were analyzed. The straw surface contact angle at different time points was measured by JC2000A contact angle measuring apparatus, optical microscope (OM) and scanning electron microscopy (SEM) combined with a linear regression technique for parameter...

Evaluation of High Solids Alkaline Pretreatment of Rice Straw

Fresh-harvested, air-dried rice straw was pretreated at a water content of 5 g H(2)O/g straw using sodium hydroxide (NaOH) and compared to pretreatment at 10 g H(2)O/g straw by hydrated lime (Ca(OH)(2)). Full factorial experiments including parallel wash-only treatments were completed with both sources of alkali. The experiments were designed to measure the effects of alkaline loading and pretr...

Biosorption of Nickel by Barley Straw

Comparison of different ionic liquids pretreatment for barley straw enzymatic saccharification

Recently, application of ionic liquids due to their special solvency properties as a promising method of pretreatment for lignocellulosic biomass has received much attention. Chemical stability, temperature stability, non-flammability, low vapor pressure, wide liquidus range, and non-toxicity are among those unique properties. These solvents are also known as green solvents due to non-toxicity ...

Optimization of the Alkaline Pretreatment of Rice Straw for Enhanced Methane Yield

The lime pretreatment process for rice straw was optimized to enhance the biodegradation performance and increase biogas yield. The optimization was implemented using response surface methodology (RSM) and Box-Behnken experimental design. The effects of biodegradation, as well as the interactive effects of Ca(OH)2 concentration, pretreatment time, and inoculum amount on biogas improvement, were...
