In this study, the effect of using olive stone residues (OSR) on some properties particleboard was investigated. For purpose, particle boards were manufactured from particles white poplar (Populus Alba L.), which partially substituted with OSR in amounts 10 %, 20 % and 30 %. addition, containing OSR, had previously been chemically modified NaOH solution, produced. Phenol formaldehyde adhesive u...

Typical biomass torrefaction is a mild pyrolysis process under conditions of ordinary pressure, low temperature (200–300°C) and inert atmosphere. Torrefaction considered to be competitive technology for pretreatment, but its impacts on the emissions particulate matter from combustion are worthy further study. In this paper, three kinds biomass, i.e., bagasse, wheat straw sawdust were selected p...

Using various Sodium hydroxide (NaOH) concentrations (0, 1, 2, and 3%), we studied the alkaline pretreatment of microalgal biomass from blue-green alga Nostochopsis lobatus in this work. In stage, entrapped polysaccharides found within microalgae cell walls are broken down to form fermentable subunits. The selected procedure (2% NaOH) was then followed by enzymatic saccharification for generati...

Herbal waste of processed medicinal plants of a local pharmaceutical industry was pretreated by steam explosion (160C for 0.5 – 2.0 h), and the process was accelerated by the use of Conc. H2SO4 (0.5 – 2.0%, 160 C for 0.5 – 2.0 h), NaOH (0.5 – 2.0%, 160C for 0.5 – 2.0 h). Significant increase in the content of reducing sugars was found after acid/alkali pretreatment of steam exploded herbal biom...
