Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Spent Hydroprocessing Catalysts, Second Edition, covers all aspects of spent hydroprocessing catalysts, both regenerable and non-regenerable. It contains detailed information on hazardous characteristics of spent and regenerated catalysts. The information forms a basis for determining processing options to make decisions on whether spent catalysts can be either reused on refinery site after regeneration or used as the source of new materials. For non-regenerable spent catalysts, attention is paid to safety and ecological implications of utilizing landfill and other waste handling and storage options to ensure environmental acceptance. As such, this handbook can be used as a benchmark document to develop threshold limits of regulated species. Includes experimental results and testing protocols which serve as a basis for the development of methodologies for the characterization of solid wastes Presents a database which assists researchers in selecting/designing research projects on spent catalysts, i.e., regeneration vs. rejuvenation and metal reclamation Provides the environmental laws, acts, and liabilities to raise awareness in safety and health issues in all aspects of spent catalysts Contains solid waste management procedures specific to hydroprocessing that serve as a model for designing research projects in other solid waste areas

Download or read book Hydroprocessing Catalysts And Processes The Challenges For Biofuels Production written by Seddon Duncan and published by World Scientific. This book was released on 2018-04-05 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for hydroprocessing catalysts has shown an increasing trend, because of their applications in refining of petroleum and biofuels, in order to comply with strict environmental regulations controlling emissions from transportation vehicles. Transport fuel is dominated by fossil fuels with carbon emission intensive production methods. If we are to move away from these sources, the alternative is to produce liquid fuels from agricultural stocks -- crops, crop waste, forestry waste or algae. Converting these feedstocks into high quality fuels is a considerable challenge. By describing the current status in processing agricultural feedstock into high quality liquid transport fuels, the authors set out the means to develop better chemistry and catalysis for the necessary conversion processes. This book offers an intriguing insight into the mechanisms and protocols involved in new hydroprocessing catalysts and processes, and covers the methods for upgrading these liquids to modern transport vehicles suitable for operation in modern gasoline and diesel engines. It provides an introduction to the mechanism of hydroprocessing reactions, application of different metals in hydroprocessing, the effect of catalyst supports, applications in refining new feedstock, renewable fuels standards, the management of spent hydroprocessing catalysts, and hydrogen production. Hydroprocessing Catalysts and Processes will prove useful for both researchers in academe and industry concerned with future fuels development and treatment to produce current and future liquid transport fuels.

Download or read book Waste Management and the Environment VII written by C. A. Brebbia and published by WIT Press. This book was released on 2014-05-12 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of the 7th International Conference on Waste Management and the Environment follows on from the success of previous meetings held in Cadiz (2002), Rhodes (2004), Malta (2006), Granada (2008), Tallin (2010) and the New Forest (2012). There is growing awareness of the detrimental effects of current waste disposal and a movement towards greater accountability for effective waste management. Better practices and safer solutions are required. This creates a need for more research on current disposal methods such as landfills, incineration, chemical and effluent treatment as well as recycling, waste incineration, clean technologies, waste monitoring, public and corporate awareness, and general education. Waste Management is one of the key problems of modern society due to the ever expanding volume and complexity of discarded domestic and industrial waste. Unfortunately many of the policies adopted in the past were aimed at short term solutions without due regard to the long term implications on health and the environment, leading in many cases to the need to take difficult and expensive remedial action. The desired direction of waste management is towards sustainable strategies. The approach which has emerged as the most sustainable strategy has been called 3Rs, where reduction, reuse and recycling, in this order, are seen as the best actions. Recently recovery is added as the fourth action (4Rs) applied in order to; for example, recover energy from waste that cannot be classified under the 3Rs. This largely decreases the volume of the waste that needs final disposal. Further steps are required towards improvement of current technologies, increased collaboration between the public, government and private sectors and increased involvement of all stakeholders. Topics covered include: Environmental impact; Reduce, reuse, recycle and recovery (4Rs); Cost and benefits of management options; Waste incineration and gasification; Energy from waste; Industrial waste management; Nuclear and hazardous waste; Agricultural waste; Wastewater; eWaste; Landfill optimization and mining; Remote sensing; Thermal treatment; Emergent pollutants; Environmental remediation; Legislation; Behavioural issues.

Download or read book Natural and Synthetic Waxes written by Ernst Krendlinger and published by John Wiley & Sons. This book was released on 2023-01-10 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural and Synthetic Waxes A compilation of all relevant information for the production and use of waxes in technical applications Waxes are among the oldest organic substances used by mankind. Before all others, beeswax is known to have played a role in human history for thousands of years. But over time, many other wax species have been detected and exploited, and prepared for different utilizations. Today, we possess knowledge of a great variety of different types of waxes. Unfortunately, there still is no broadly accepted definition of a wax: for the relatively few wax chemists, waxes are usually defined by their physico-chemical properties more than by their chemical constitution. Waxes are not uniform but oligomeric and polymeric substances, not simply describable with a chemical formula. The realm of waxes encompasses fully or partly natural, refined, partly or fully synthetic products, which can be extended by “wax-like” products which do not fulfil all definition criteria. Waxes are offered in different forms like pellets, granules, powders, or micropowders. Their number of technical applications runs into thousands. However, waxes in most cases are just adjuvants or additives, and with few exceptions like candles not known to a broader public. Only few publications over the last decades tried to present a more comprehensive overview of heir chemistry, chemical composition, their physical and analytical properties, their applications, and their sometimes astonishing history. Based on personal experience and expertise, the authors intend to present an overview on the main classes of waxes, their origin, history, future, and potential fate. Economical aspects like market size and development, ecological impacts and challenges, and regulatory issues are also addressed. Waxes are indispensable products in everyday life and in industry and technology, though mostly not even visible or distinguishable to experts. They deserve more than the role of a “poor cousin” in chemistry and technology.
