Multiphase Catalytic Reactors: Theory, Design, Manufacturing, and Applications
FOCUS in Bochum, Germany, have developed the first photobioelectrochemical cell that combines a native photosystem I (PSI) and an enzyme (glucose dehydrogenase or glucose oxidase) to oxidize glucose and produce electricity. The integrated PSI/enzyme systems convert sunlight into electrical power via the light-triggered PSI-stimulated oxidation of a biomass substrate. Researchers are now attempting to raise the amount of PSI/enzyme conjugates on the electrode to boost photocurrent generation.

PATENTS Bioremediation method for accelerated biological decomposition of petroleum hydrocarbons in sea ice-covered polar regions, and bacteria and enzyme mixtures as agents for carrying out said method A bacterial mixture usable in an inoculum is useful in a bioremediateion method for accelerated biological degradation of petroleum hydrocarbons in a sea ice-covered polar region includes a plurality of isolated coldadapted autochthonous bacterial strains. Each of the bacterial strains has petroleum hydrocarbons degrading activity at an ambient temperature of -3.degree. C. and each has a different temperature tolerance range, a different salinity tolerance range, a different petroleum hydrocarbons degradation spectrum, and a different capacity to emulsify oil.

Process for methanol coupled catalytic cracking reaction of naphtha using a modified ZSM-5 molecular sieve catalyst This invention describes a process for methanol coupled catalytic cracking reaction of naphtha using a modified ZSM-5 molecular sieve catalyst, comprising performing a co-feeding reaction of methanol and naphtha on the modified ZSM-5 molecular sieve catalyst to produce low carbon number olefinic and/or aromatic hydrocarbons. The naphtha and methanol concurrently pass through the catalyst bed, which are reacted during contacting with the catalyst under a reaction condition of a reaction temperature of 550-670oC, a mass ratio of methanol to naphtha of 0.05-0.8, and a total mass space velocity of naphtha and methanol of 1.0-5 h-1.

Catalytic Hollow Fibers This invention involves a hollow fiber for use in production of hydrogen gas. The hollow fiber contains a porous support layer having an outer surface and an inner surface, a catalyst layer coated on the outer surface, and a selection layer coated on the inner surface. Methods for preparing such a hollow fiber catalysts are described. US 9,272,269, National University of Singapore, Singapore, SG, 1, MAR 2016.
BOOKSHELF Lewis Base Catalysis in Organic Synthesis This two-volume set is a comprehensive coverage of the rapidly expanding field of Lewis base catalysis that has attracted enormous attention in recent years. Lewis base catalysis encompasses an extremely wide variety of useful transformations. These catalysts are particularly effective for enantioselectively constructing new stereogenic centers. As electron-pair donors, Lewis bases can influence the rate and stereochemical course of myriad synthetic organic reactions. The edition summarizes the conceptual/ mechanistic principles that underlie Lewis base catalysis, and then builds upon that foundation with a thorough presentation of many different reaction types. The two well-respected
authorities in the field of Lewis base catalysis have compiled quality contributions from an impressive collection of international experts. E. Vedejs and S. E. Denmark (eds), 1st edn, 2016, Wiley-VCH, Weinheim, ISBN-13: 978-3527336180, 1488 pp.
Liquid Phase Aerobic Oxidation Catalysis: Industrial Applications and Academic Perspectives This text is a timely overview of the field of aerobic oxidation reactions in the liquid phase and attempts to link developments to industrial applications. The text also highlights some of the key catalytic and reactor design challenges that lie ahead. Both homogeneous and heterogeneous chemocatalysis and biocatalysis are addressed. Most importantly, the text provides examples taken from various industries including bulk chemicals and monomers, specialty chemicals, flavors and fragrances, vitamins, and pharmaceuticals. One chapter is devoted to reactor design concepts and reactor engineering aspects, while another deals with the relevance of aerobic oxidation catalysis for the conversion of renewable feedstocks. S. S. Stahl and P. Alsters (eds), 1st edn, 2016, Wiley-VCH, Weinheim, ISBN-13: 978-3527337811, 436 pp.
Multiphase Catalytic Reactors: Theory, Design, Manufacturing, and Applications This authoritative book provides a broad assessment of multiphase catalytic reactors from their modeling and design to their applications in industrial manufacturing of chemicals. The authors address theoretical aspects of various multiphase chemical reactors and provide rich examples of applications of fixed-bed, fluidized-bed, trickle-bed, slurry, monolith, and microchannel reactors. The text also includes chapters covering experimental techniques and practical guidelines for lab-scale testing of multiphase reactors. Mathematical models including design equations and empirical relationships characterizing different multiphase reactor types are provided. Detailed analyses of multiphase reactor applications such as Fischer-Tropsch synthesis, fuel processing for fuel cells, hydrotreating of oil fractions and biofuels processing are also included. € Z.
