Book Description
This volume contains peer-reviewed manuscripts describing the scientific and technological advances presented at the 6th Natural Gas Conversion Sumposium held in Alaska in June 2001. This symposium continues the tradition of excellence and the status as the premier technical meeting in this area established by previous meetings.The 6th Natural Gas Conversion Symposium is conducted under the overall direction of the Organizing Committee. The Program Committee was responsible for the review, selection, editing of most of the manuscripts included in this volum. A standing International Advisory Board has ensured the effective long-term planning and the continuity and technical excellence of these meetings.

Book Description
"Spillover and Mobility of Species and Solid Surfaces" collects the papers which were presented at the Fifth International Conference Spillover, either as oral or poster contributions, as well as the summaries of the invited lectures. This congress and its publication in the Studies on Surface Science and Catalysis series follow the tradition of previous conferences on spillover, initiated in Lyon, 1983, and continued in Leipzig, 1989, Kyoto 1993 and Dalian, 1997. For the fifth conference, held in S.L. el Escorial (Madrid), the organising committee has attempted to compile representative contributions which illustrate the advances in understanding the spillover phenomenon since 1997. Spillover is a process taking place during the interface of gas reactant molecules (mainly hydrogen and oxygen) on solid surfaces. However, different contributions to the more general area of the chemistry at surfaces, related with the mobility and migration of species, diffusion through membranes, fuel cell catalysts, etc., have also been included. In fact the title of the present volume summarizes this attempt to extend the conference topics towards dynamics at surfaces.Among the 70 contributions received, the 56 accepted papers were selected on the basis of the reports of at least two international reviewers, according to standards comparable to those applied for other specialised journals. These papers are from 21 different countries.

Book Description
Today, there is growing interest in aqueous-phase catalytic conversions for the valorization of renewable biomass-based feedstocks for biorefineries to produce, in a sustainable way, biofuels, chemicals, power, energy, materials, pharmaceuticals and food. This is because of the highly polar nature of water which makes it an ideal medium to convert polar biomass-based lignocellulose (cellulose, hemicellulose, lignin), with high oxygen content, and their upgraded products such as hydrophilic carbohydrates, platform chemicals and their derivatives. Another reason which makes water the solvent of choice is that water itself is involved either as a reagent or as a byproduct even in large amounts in typical conversions for the valorization of biomass. The obtained intermediates further react in the aqueous medium, often without any separation and purification, to manufacture more valuable products. This results in substantial energy savings, lower emissions and economic benefits. Furthermore, water could act as a catalyst in conversions of biomass-based feedstocks such as in liquefaction reactions under subcritical conditions. Moreover, novel types of catalytic reactivity have been observed in the aqueous solvent, not only with water-soluble transition metal catalytic complexes, but also with conventional heterogeneous catalysts and catalytic nanoparticles in a broad spectrum of different reactions such as, inter alia, aldol condensations and hydrogenation reactions. For example, in the aqueous-phase hydrogenation of the biomass-based key platform chemical levulinic acid into γ-valerolactone and beyond, employing heterogeneous catalysts and nanoparticles the presence of water has a beneficial effect and accelerates the reaction rates, whereas in organic solvents much lower activities were observed. This promotional effect of water in the hydrogenation of levulinic acid was proved by many experimental and theoretical studies using a broad spectrum of different types of catalytic systems.
