Productivity enhancement

The method based on the precipitation of peroxometalate precursors enables to achieve additional purification during the process. Thus, the addition of complexonates, such as OEDP or EDTA, which form stable complexes with some polyvalent metals, prevents co-precipitation of the main impurities such as Fe, Co, Ni, Mn, Mg, etc., which in turn significantly increases the purity of the final product. Enhanced purification can also be achieved by recrystallization of the precursor. Particularly, the precipitation of ammonium peroxofluorometalates, such as ammonium peroxofluoroniobate ((NH4)3Nb04F4), as a primary precursor, leads to significant reduction of the titanium contamination. Ammonium peroxofluoroniobate, (NH4)3Nb04F4, is... [Pg.307]

The enzymes that catalyze the conversion of one or more compounds (substrates) into one or more different compounds (products) enhance the rates of the corresponding noncatalyzed reaction by factors of at least 10 . Like all catalysts, enzymes are neither consumed nor permanently altered as a consequence of their participation in a reaction. [Pg.49]

This is a further deepened work of what Samsung Total accomplished[12-14] several years ago. Several operation conditions including hardware modification which may enhance the productivity were deduced and simulated using the simulation model. Some ideas wctb alre y applied to commercial plant when they were concluded practically reasonable while some are on the waiting list One of the examples of productivity enhancement is shown in Fig. 1 and Fig. 2 which compare the conversion profiles and MWDs under original and revised operation conditions. As shown in these two figures the productivity was mhanced while MWD docs not change much. [Pg.840]

Diastereoselectivity was observed as the result of stereoinduction (Equation (41)), giving preferential formation of the 1,2-trans products. Enhancement of the diastereoselectivity in the cycloisomerization of enyne 65a n= 1) was observed with the use of the catalyst bearing the sterically demanding Cp ligand 64. [Pg.573]

TNF-a is chemotactic for monocytes and neutrophils. Its effects on neutrophils are numerous for example, it can prime degranulation and reactive oxidant production, enhance phagocytosis and ADCC and up-regulate the expression of some surface receptors, such as CR3. Whilst low concentrations of TNF-a are required to prime the cells subsequent to stimulation by other agonists, such as fMet-Leu-Phe, higher concentrations of TNF-a alone can activate low levels of oxidant production. This activity is even more pronounced if the neutrophils are adhered to surfaces. [Pg.95]

The focus of this work was to determine if a glyco-peptide or a simple dextrinized, oxidized starch could be produced which would enhance the behavior of a starch-based polymer for spray dried flavoring production. Enhancement of a starch s lipophilic/hydrophilic balance was anticipated to maintain the polymer s film forming" and cohesive wall development during the spray drying process while improving its emulsifying/interfacial activity capabilities. [Pg.12]

It is claimed (Ref 31) that the above effects suggest that gaseous decompn products enhance the rate of decompn of solid RDX. In spread samples the activation energy is given as 63 kcal/mole ( ) over the entire decompn range, whereas for unspread samples the activation energies for induction, acceleration and max rate regimes are claimed to be 49, 43 62 kcal/mole, respectively (Ref 30)... [Pg.161]
