steam explosion
The phenomenon of steam explosion takes an important place in the analysis of severe accidents in nuclear power generation.
      
The intensity of steam explosion defines the scenario of further course of an accident.
      
A comparison with experiment confirms the validity of this approach to solving the problem on intensity of steam explosion.
      
Only the mixing of a corium jet with water at different values of pressure is studied in experiments L-14 and L-24; in experiment L-33, an initiating device is used to make a steam explosion after mixing.
      
The results of VAPEX code-aided calculations and the experimental data agree qualitatively and quantitatively both at the stage of mixing and at the stage of steam explosion.
      
Steam explosion of hardwood chips produces impurities that reduce the activity and stability of cellulases.
      
Agricultural residues were pretreated by steam explosion and the cellulosic component of these substrates were converted to ethanol using a combined enzymatic hydrolysis and fermentation (CHF) process.
      
Effect of steam explosion on the physicochemical properties and enzymatic saccharification of rice straw
      
The effects of steam explosion pretreatment on the physical and chemical properties of rice straw and on the enzymatic saccharification of the straw were investigated.
      
Rice straw was very finely defiberized by steam explosion.
      
The steam explosion products were separated into hemicellulose, cellulose, methanol-soluble lignin, and klason lignin.
      
Steam explosion pretreatment of potato for the efficient production of alcohol was experimentally studied.
      
Steam explosion of straw in batch and continuous systems
      
The chips were first impregnated with dilute sulfuric acid, then pretreated in a steam explosion reactor to hydrolyze, more than 90% of the hemicellulose and approx 10% of the cellulose.
      
Prehydrolysis with dilute acid and steam explosion constitute the most promising methods for improving enzymatic digestibility of biomass for ethanol production.
      
Optimization of steam explosion to enhance hemicellulose recovery and enzymatic hydrolysis of cellulose in softwoods
      
The MSW was pretreated with dilute sulfuricacid (0.4% w/w) at 210°C for 3 min in a 4-L stea mexplosion reactor, then washed with water to recover the solubilized hemicellulose.
      
The nature of lignin from steam explosion/enzymatic hydrolysis of softwood
      
Effective utilization of the lignin by-product is a prerequisite to the commercial viability of ethanol production from softwood wastes using a steam explosion (SE)/enzymatic hydrolysis (EH)/fermentation process.
      
Whole-tree chips were impregnated with dilute sulfuric acid and steam treated in a 4-L steam explosion reactor.
