Principally, when the gas from the digester was entered in the absorber an equal volume of NaOH solution was displaced from the absorber into the measuring cylinder.
(Singh and Gupta, 2012) presented similar results and found non-significant difference in Dry Matter intake of Karan Fries calves fed on 5.0% NaOH treated rice husk and wheat straw.
Because the catalysts mentioned above had not yet been studied in the glycolysis reactions of PUs, except for NaOH, and that the solvent choice was important in the depolymerization reaction yield, there is an interest in studying better reaction conditions to achieve even higher conversion rates.
Basic groups contents were also determined by back titration of the filtrate with 0.01 M x NaOH solution.
(6) Step 6: calculation of individual mass of AAS content (NaOH and [Na.sub.2]Si[O.sub.3] solutions)
It is also evident that the percentage of NaOH is directly related to all the mechanical properties and composite, treated with 7 (w/v) % NaOH showing better mechanical properties.
When comparing the performance of the Pd-Cl/C and Pd-N/C catalysts similar behavior is observed in presence of NaOH, but is distinct when is used CaCO3 and especially the differences in activity observed between PdCl/C and PdN/C could be attributed to, at least in part, to the residual chlorine on the catalyst surface and to the electronic effects due to electrodeficient species present on the chloride catalyst.
Glycerol oxidation process parameters like NaOH initial concentration [c.sub.0](NaOH) = 0-1.5 mol/L, glycerol and palladium molar ratio n(glycerol)/n(Pd) = 300-1000 mol/mol, reaction temperature 45-60 [degrees]C and oxygen pressure from 1 to 6 atm were varied.
The mineral composition of the WHB ash specimens made of mixtures with sodium silicate based solutions differs considerably from that of the samples treated with water or NaOH. A major difference between the fresh ash and water and NaOH mixed samples is in the amorphous phase content, which, differently from the constant 14 wt% in the former, varies from 6 to 52 wt% in the samples mixed with Na-silicate, depending on its amount added (Fig.
(1985), as follows: samples of 0.5g dry soil were subjected to sequential extraction with anion-exchange resin (AER-Pi); NaHC[O.sub.3] 0.5mol [L.sup.-1] (NaHC[O.sub.3]-Pi and NaHC[O.sub.3]-Po); HCl 1.0mol [L.sup.-1] (HCl-Pi) and NaOH 0.5mol [L.sup.-1] + ultrasound (NaOH-Pi and NaOH-Po).
OPMF hydrolysate was prepared by pretreating OPMF with alkaline sodium hydroxide (NaOH) and followed by enzymatic hydrolysis.
[6] had studied the thermal behaviour of NaOH treated sisal fibre using TA Q5000 IR.
The gas (C[O.sub.2] and water vapour) was adsorbed with NaOH solution.
