PAPER TITLE

This work reported a well dispersed copper-based catalysts prepared by a modified ammonia evaporation method with ordered mesoporous silica (OMS) as the precursor of the support. During the aging stage, the lower pH value of the precursor solution can protect the destruction of ordered mesoporous structure of OMS, which plays an important role in homogeneous pre-distributing copper precursor in the support. So that more copper phyllosilicate or surface Cu-O-Si species could be produced during the ammonia evaporation stage, resulting in large surface areas of both Cu0 and Cu+ species in the final catalysts (shown in Figure 1). The catalysts with various copper loading were systematically characterized and applied in the hydrogenation of dimethyl oxalate (DMO) to ethylene glycol (EG). An excellent low-temperature catalytic performance and stability were achieved on 20Cu/OMS with EG selectivity of 98.2% at 453K, due to the superior surface areas of both Cu0 and Cu+, as well as the highest ratio of Cu+/ (Cu0+Cu+). The catalytic activity was strongly dependent on the amount of Cu0 or Cu+, indicating that both Cu0 and Cu+ are the active sites for the DMO hydrogenation. The space time yield of EG (STYEG) presented a positive correlation with the copper surface areas, especially Cu0 species. This novel approach showed prospective future in well fabricating high efficient industrial catalyst.
Annual world rice (Oryzae sativa ) production is about 618 million metric tons (In year 2005). For every ton of grain harvested, about 1.35 ton of rice straw remains in the field. Rice straw has a high potential as a source of lignocellulosic biomass because of the high yield of rice straw per hectare. It can be handled by new processes to manufacture cellulosic fibers, lignin, furfural and other by products. Delignification (pulping) reaction of rice Straw was carried out in small stainless steel air tight jars placed in lab digester at controlled temperature. Acetic acid was used as main chemical and H2SO4 was used as catalyst. The unbleached pulp was bleached by DED bleaching sequence. Decorative laminates are typically comprised of an assembly of three layers; a core layer, a print layer and a surface layer. Decorative laminates, particularly high pressure laminates, find utility in manufacture of furniture, kitchen counter tops, table tops, store fixtures, wall paneling, partitions, doors, bathroom and kitchen work surfaces and wall paper. Inert filler materials (TiO2, CaCo3, Clay etc.) are used in the paper core sheets to give high opacity, mechanical strength and surface properties. TiO2 is particularly useful as filler because of its high optical scattering power resulting from its high refractive index. Titanium dioxide is relatively expensive compared to other fillers that are used in the paper industry, but its optical properties produces high degree of opacity and brightness in the core sheet and the resulting decorative laminates. The brightness of unbleached paper (made of received pulp) is 26 - 27 % ISO (measured at 457 nano meters). The opacity of paper is 98%, which is very high and good for several grades.The burst index and tear index of sample paper is 0.6 -0.65 Kpa.m2/g and 4.5 - 4.7 mN.m2/g respectively.
