Kinetic study of the hydrothermal reaction between lime and rice-husk-ash silica
(Elsevier Limited, 1992)
The paper describes a study of the reaction between lime and amorphous silica obtained from rice-husk (93-94% SiO2) under hydrothermal conditions, in the range 80-140°C. The progress of the reaction, conducted in stainless ...

Pretreatment of wheat straw using combined wet oxidation and alkaline hydrolysis resulting in convertible cellulose and hemicellulose
(John Wiley & Sons Inc., 1996)
The wet oxidation process of wheat straw has been studied as a pretreatment method to attain our main goal: To break down cellulose to glucose enzymatic, and secondly, to dissolve hemicellulose (e.g., for fermentation) ...

A film diffusional effect on the apparent kinetic parameters in packed-bed immobilized enzyme reactors
(John Wiley & Sons, Inc., 1997-08)
A film diffusional effect on the apparent kinetic parameters in packed-bed reactors containing the enzyme immobilized on the surface of a nonporous support was investigated. A comparison of the plug-flow reactor model ...
Hot corrosion behaviour of Nickel-200 alloy in presence of Sodium salts at 850°C
(Academy Science Publishers/African Academy of Sciences (AAS), 1996)
The hot corrosion behaviour of Nickel-200 industrial alloy has been investigated in presence of Na2S04, NaCI, NaN03, Na2C03 and Na202 at 850°C in flowing air. The hot corrosion kinetic and effect of salt deposition on the ...
Mass transfer effects in solvent-free fat interesterification reactions: influences on catalyst design
(John Wiley & Sons, Inc., 1994-01-01)
The use of solvent-free systems in the oil and fats industry is commonplace. Initial studies on interesterification were carried out in solvent systems because the lipase was immobilized solely by adsorption onto particles ...
The CsCl- and CsN03-induced high temperature oxidation of Nimonic-90 alloy at 1123 K
(Elsevier Science B.V., 1996)
Nickel-base alloys find vital scope in space and nuclear applications due to their numerous favourable properties such as low density, high strength and corrosion resistance. The high temperature oxidation of Nimonic-90 ...
Silica gel from rice hull ash: preparation and characterization
(American Association of Cereal Chemists, Inc., 1998-07)
Rice hulls, a waste coproduct of the rice industry, is composed of 20% silica. The objectives of this study were to develop a method to recover silica from rice hull ash and produce silica gel, and to determine the physical ...
