Oxidative delignification of wood or wood pulp by transition metal-substituted polyoxometalates by Rajai H Atalla( Book )

1 edition published in 1997 in English and held by 1 WorldCat member library worldwide

A method for delignifying wood pulp and fiber is disclosed. The method comprises the steps of obtaining a wood pulp and exposing the wood pulp to a polyoxometalate of the formula V[subscript l]Mo[subscript m]W[subscript n]Nb[subscript o]Ta[subscript p](TM)[subscript q]X[subscript r]O[subscript s][superscript x] where 1 is 0-18, m is 0-40, n is 0-40, o is 0-10, p is 0-10, q is 0-9, r is 0-6, TM is a d-electron-containing transition metal ion, and X is a heteroatom which is p or d block element, provided that l+m+n+o+p[> or =]4, l+m+q>0 and s is sufficiently large that x>0. The exposure is under conditions wherein the polyoxometalate is reduced. In a preferable form of the invention, the method additionally comprises the step of reoxidizing the polyoxometalate

THE ROLE OF INERTS IN HYDROCARBON FLAMES( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

The role of inerts in hydrocarbon flames close to heat sinks was explored in a spectrophotometric study of low pressure flat butane-oxygen flames to which were added different amounts of nitrogen while as many other variables as possible were held constant. Measurements of flame temperatures led to the discovery that the presence of an inert can bring about reductions in the heat losses to the sink, which can more than compensate for the effect of thermal dilution. Thus, flames containing nitrogen were found to possess higher temperatures than those of the pure fuel oxidant mixture when burned at the same rate. A theoretical analysis leads to conclusions which are in agreement with the experimental results. Variations in the intensity profiles of emitters in the main reaction zone can be interpreted in terms of the increased resistance to diffusion attending nitrogen addition and the higher frequency of termolecular collisions relative to bimolecular collisions.

Press Dry Conference 1983 Held at Madison, Wisconsin on September 7-9, 1983( Book )

1 edition published in 1983 in English and held by 1 WorldCat member library worldwide

The purpose of this presentation is to provide an overview of the overall Institute program. Details of particular aspects of the research have been, and will continue to be, published elsewhere. Water removal concepts directed toward the reduction or elimination of some of the barriers to rapid, efficient drying (as exist in conventional dryers) are the primary subjects of research at the Institute. The concepts being investigated form a family, in that they are all based on the principle of high-intensity drying. High-intensity drying refers to drying under sufficiently intensive heat input conditions that the moist paper web is maintained at a temperature in excess of the ambient boiling point

Oxidation of lignin and polysaccharides mediated by polyoxometalate treatment of wood pulp( Book )

1 edition published in 1996 in English and held by 1 WorldCat member library worldwide

A method for oxidative degradation of lignin and polysaccharide fragments dissolved during polyoxometalate delignification or bleaching of wood pulp, wood fiber or pulp obtained from a non-woody plant. The method comprises the steps of obtaining a spent polyoxometalate bleaching solution containing a polyoxometalate of the formula V[subscript l]Mo[subscript m]W[subscript n]Nb[subscript o]Ta[subscript p](TM)[subscript q]X[subscript r]O[subscript s][superscript x] where 1 is 0-18, m is 0-40, n is 0-40, o is 0-10, p is 0-10, q is 0-9, r is 0-6, TM is a d-electron-containing transition metal ion, and X is a heteroatom which is p or d bock element, provided that l+m+n+o+p[> or =]4, l+m+q>0 and s is sufficiently large that x>0, and heating the solution inthe presence of an oxidant under conditions wherein the dissolved organic compounds are oxidataively degraded to volatile organic compounds and water
Raman microprobe investigation of molecular structure and organization in the native state of woody tissue by Rajai H Atalla( Book )

1 edition published in 1984 in English and held by 0 WorldCat member libraries worldwide

Although the primary emphasis of our program has remained with the application of Raman spectroscopy to the study of native tissue, the scope of the work has been expanded to include a number of complementary approaches. These have included Solid State 13C NMR, autoradiography of radiolabeled woody tissue sections, and the generation of biomimetic tertiary aggregates which simulate states of aggregation characteristic of cell walls. Our Raman spectroscopic studies have resulted in progress in the areas of interpretation of the spectral features, and confirmation of the variability of the patterns of orientation of lignin reported earlier. We have assembled and made operational our new microprobe and spectrometer systems acquired under the DOE-URIP program. We have also demonstrated that, operating with gated detection and pulsed laser excitation, we can discriminate against the laser-excited fluorescence characteristic of most woody tissue. Our studies of celluloses, which combine Raman spectroscopy and 13C NMR have shown that all native celluloses are composites of two forms which have the same secondary structure but different tertiary structures
