Present study demonstrated the preparation of MCM-41 as a support for the immobilization of Candida rugosa lipase by the physical adsorption technique. The lipase immobilized MCM-41 has been characterized by scanning electron microscopic and FTIR techniques. At pH 6, maximum lipase immobilization (250 mg/g) on MCM support has been observed and the immobilized lipase was employed as biocatalyst ...

The catalytic cracking of a fuel oil over fluid catalytic cracking (FCC) catalyst has been investigated applying different additives. Catalyst mixtures consisting of a equilibrium FCC catalyst (E-Cat) blended with ZSM-5, MCM-41 and Mordenite additives were examined at the additive levels of 25 wt.%. The catalytic performance of the matrix was studied in a fixed bed micro-activity test unit (MAT...

The observation of molecular clusters has been of interest for some time. Molecular clusters can show quite different dynamic and static phase behaviour from bulk systems, and, because of their limited size, are accessible to computational molecular dynamics techniques.1-3 Experimentally, molecular clusters are made using several methods, including supersonic jets, vapours, confinement of phase...
