Ammonium Hydroxide Treatment of Wheat Straw
Chopped wheat straw, containing increasing amounts of added water was treated with a constant level of ammonia (3.3 percent of straw dry matter) as ammonium hydroxide, and stored for I to 60 days before determing in vitro dry matter digestibility (IVD MD), nitrogen content and fiber-bound nitrogen (ADF-N) versus free ammonia nitrogen (NH3N) of the treated sample. The overall improvement (e.g., ...
متن کاملFungal treatment of sugarcane straw for organosolv pulping
544 The scientists at Engineering College of Lorena, Brazil and Faculty of Chemical Engineering, Colombia reported the effect of fungal pretreatment of sugarcane straw in the performance of the treated pulps. Fermentation time, fungal mycelium load and pretreatment scale were studied in the fungal treatment, and the best conditions were 15 days with Fungal treatment of sugarcane straw for organ...
متن کاملMicroscopic potassium hydroxide preparation.
Procedure 1. Place the specimen on a clean glass slide. Add 1 drop of 20% KOH. 2. Place the cover glass on top of the slide and gently press to get rid of any air bubbles. Blot excess solution from the finished slide preparation with the gauze. 3. Place slide on the microscope stage and start with a low-power (10 ×) examination. To make epithelial cells visible, reduce illumination by lowering ...
متن کاملPreparation of Activated Carbon from Lignin Obtained by Straw Pulping by Koh and K2co3 Chemical Activation
Activated carbon was prepared through chemical activation of lignin from a straw pulping precursor, using K2CO3 and KOH as chemical agents. To optimize the preparation method, the effect of the main process parameters (such as impregnation ratio, activation temperature and activation time) on the performance of the obtained activated carbon (expressed in terms of iodine number and yield of acti...
متن کاملResearch on Wheat Straw Pulping with Ionic Liquid 1-Ethyl-3-Methylimidazole Bromide
In this paper, the pulping process of wheat straw using ionic liquid 1-ethyl-3-methylimidazolium bromide ([Emim]Br) as the digestion liquor is presented. The influence of pulping conditions on the pulp yield are analysed by single-factor and orthogonal experiments, and optimum pulping conditions are obtained. The average pulp yield reaches 44 %, and the average recovery rate of ionic liquid is ...
