Electro-Catalysis at Chemically Modified Solid Surfaces
FOCUS of the Surf ‘n’ Turf project, a Sustainable Energy Strategy for Orkney was unveiled, which aims to achieve ambitious carbon reduction targets; position Orkney as the globally recognized innovation region to develop solutions for the world’s energy systems challenges; decrease and eradicate fuel poverty in Orkney; maximize economic opportunity and investment in Orkney; and ensure a secure energy supply during transition to a low-carbon future. The next step will involve the formation of an action plan to help the islands reach these targets.

PATENTS Catalyst system for olefin polymerization and method for producing olefin polymer A phthalate-free catalyst component for olefin polymerization comprises titanium, magnesium, a halogen, diether, and oxalic acid diamides represented by an olefin polymerization catalyst system consisting of the solid catalyst component, an organoaluminum compound, and an optional external electron donor compound. The present catalyst compositions improve diether-based catalyst selectivity while maintaining excellent catalyst activity and hydrogen response. An olefin polymer that has a moderate molecular weight distribution while maintaining higher stereoregularity (isotacticity) over diether-based catalyst, and better than or equal to phthalate-based catalyst can be produced by utilizing the inventive catalyst component. US 9,777,084, Formosa Plastics Corporation, Livingston, NJ USA, 3 OCT 2017.
Process and apparatus for hydroprocessing and cracking hydrocarbons A process and apparatus is described for recycling LCO and/or HCO to an FCC unit to recover additional distillate. Spent catalyst recycle in the FCC unit may be used to improve distillate yield. A hydroprocessing zone may saturate cycle oil aromatics for cracking in an FCC unit. The recycle cracked stream may be recycled to a downstream hydroprocessing zone to avoid a first hydroprocessing zone for hydrotreating feed to the FCC unit. Additional recovery of cycle oil for recycle is obtained by heating slurry oil prior to vacuum separation. US 9,777,229, UOP LLC, Des Plaines, IL USA, 3 OCT 2017.

Process for producing oxygen reducing catalyst and uses thereof A process for producing an oxygen reducing catalyst including a step of heat-treating, in a non-oxidizing atmosphere, a catalyst precursor including a compound (i) supplying a carbon element and a nitrogen element by heating in a non-oxidizing atmosphere, and a compound (ii) containing at least one element of iron and cobalt. Also disclosed is an oxygen reducing catalyst, a fuel cell catalyst layer including the oxygen reducing catalyst, an electrode including the fuel cell catalyst layer, a membrane-electrode assembly including the electrode and a fuel cell including the membrane-electrode assembly.

Cross-linked membranes US-based Chevron Inc. has been granted Patent No WO/2016/191089 (Publication date: 1 Dec 2016) for a process for preparing a cross-linked membrane, for example, a cross-linked hollow-fibre membrane. The method involves producing a polyimide polymer consisting of carboxylic acid functional groups, from a reaction solution containing at least one solvent and monomers. The polyimide polymer is treated with a diol under esterification conditions to produce a monoesterified polyimide polymer, then a monoesterified polyimide membrane. The monoesterified polyimide membrane is exposed to transesterification conditions under a carbon dioxide atmosphere to produce a cross-linked polyimide membrane.

Chemically and UV cross-linked high selectivity polyimide membrane for gas separation US-based UOP LLC has been granted Patent No WO/2016/209690 (Publication date: 29 Dec 2016) for a membrane composition for gas separation, and a process for preparing it. Based on gas permeation tests, the chemically and UV cross-linked polyimide membrane has high selectivity and resistance to solvents and plasticization. The material can be used for a wide range of processes, including light gas separation and liquid separation.

BOOKSHELF General Base Catalysis Hydrolysis of Chloropyrifos This book is written for researchers working in the field of physical and organic chemistry. Its focus is the catalytic hydrolysis of pesticides and insecticides. With the growing use of pesticides and insecticides, their accumulation in the environment becomes unavoidable. The solubility of chloropyrifos in water is potentially very harmful to living organisms beyond the targeted insects. This book examines the kinetics and hydrolysis of chloropyrifos catalyzed with different types of amines including n-butylamine, imidazole, hydrazine, ammonia, and ethanolamine. A. Kulshreshtha and C. P. Shinde, 1st edn, SEP 2017, Lap Lambert Academic Publishing GmbH & Co. KG, Saarbru¨cken, GE, ISBN-13: 9783659855528, 56 pp.
Catalysis: Concepts and Green Applications The second edition of this popular introductory textbook covers all aspects of catalysis. It has been updated and expanded with new information on computational methods, industrial applications and green chemistry, with over 700 references. The author, a renowned researcher in catalysis, teaches scientific writing as well as chemistry. This makes him the ideal person to write such a textbook. The effectiveness of his practical approach has been well proven in courses for undergraduates and graduates (in 2007 he was voted “lecturer of the year” by the chemistry students) at the University of Amsterdam. Following an introduction to green chemistry and the basics of catalysis, the book covers biocatalysis, homogeneous catalysis and heterogeneous catalysis, as well as computer applications in catalysis research. Each chapter also features integrated exercises that help teachers and students better learn essential information. G. Rothenberg, e-textbook 2nd edn, OCT 2017, Wiley-VCH Verlag GmbH & Co.
