Immobilization Of Lipase On Metal Organic Frameworks For Biodiesel Production, Reem L Safwan Shoma
Immobilization Of Lipase On Metal Organic Frameworks For Biodiesel Production, Reem L Safwan Shoma
Theses
For the economical application of enzymatic processes in biodiesel production, lipase enzyme has to be used in immobilized form to allow easy retention and reuse. The main challenges facing the industrialization of the enzymatic process are the high mass transfer resistance, the tendency to adsorb the by-product glycerol onto the support matrix and poor operational stability. These problems can be solved by a good selection of supports of favourable surface characteristics and pore sizes. In that regard, increasing interest has recently been in Metal-Organic Frameworks (MOFs) as a new kind of porous support for enzyme immobilization. Physical adsorption, which is …
Investigation Of The Effect Of Supercritical Carbon Dioxide Extraction On The Adsorption Capacity Of Date Pits, Haliemeh Imad Sweidan
Investigation Of The Effect Of Supercritical Carbon Dioxide Extraction On The Adsorption Capacity Of Date Pits, Haliemeh Imad Sweidan
Chemical and Petroleum Engineering Theses
This thesis aims to develop and investigate an innovative use of date pits, a common and abundant agricultural waste in the UAE. It is suggested that date pits may be used to produce date pit oil, and the powder residue from this extraction process may be used as a low cost adsorbent for removal of lead from water. This thesis aims to investigate the effects of the parameters pressure, temperature, and particle size on the extraction yield when using supercritical carbon dioxide (SC-CO₂) to extract oil from date pit powder. This oil is a valuable component which has many applications …
