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

This handbook serves scientists and researchers interested in any aspect of spent hydroprocessing catalysts. Its aim is to assist in the analysis and assessment of refined catalyst byproducts and processing options, to determine whether spent catalysts can be processed into productive resources. For non-regenerable spent catalysts, the book takes into consideration both safety and ecological implications of utilizing landfill and other waste options. - Provides comprehensive guidance and assistance to those making decisions on the fate of spent catalysts, radically improving strategic options for refining organisations - Offers solutions that maximize procedural, regulatory, safety, and preparedness benefits - Contains detailed information on hazardous characteristics of spent and regenerated catalysts with deployment recommendations, and acts as a benchmark document for establishing threshold limits of regulated species as well as for developing procedures for handling spent catalysts to ensure environmental acceptance

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.

Waste management can be problematic. Especially with the emphasis in many countries now being on sustainability, there is a great need for more research on disposal methods. While we have found ways to reduce the volume of waste that needs to disposed. questions remain about the environmental and safety aspects of certain recycled materials and the by-products of waste management activities, current technology improvements, and regulatory and monitoring problems. Featuring papers published at the Sixth International Conference on Waste Management and the Environment, this book contains contributions on the topics such as: Advanced Waste Treatment Technology, Wastewater Treatment; Resources Recovery; Waste Incineration and Gasification; Waste Pre-Treatment; Separation and Transformation; Landfills; Soil and Groundwater Clean-up; Public Awareness; Air Pollution Control; Hazardous Waste, Waste Management; Construction and Demolition Waste Costs; Waste Reduction; Reuse and Recycling, Energy from Waste; Electrical Waste; Rare Metals; Computer Modelling; Methodologies and Practices; Risk Assessment; Nuclear Waste; Environmental Economics Assessment; Laws and Regulations; Biological Treatments; Agricultural Wastes.

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.

Containing the proceedings from the 9th International Conference on Waste Management and the Environment, this book is a collection of research on current waste disposal methods, as well as highlighting better practices and safer solutions for the future. 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. Society is increasingly aware of the need to establish better practices and safer solutions for waste disposal. This requires further investigation into disposal methods and recycling as well as new technologies to monitor landfills, industrial mining wastes and chemical and nuclear repositories. This creates a need for more research on current disposal methods such as landfills, incineration, chemical and effluent treatment, as well as recycling, clean technologies, waste monitoring, public and corporate awareness and general education. The papers contained in this title form a collective record of scientific information and work on the current situation of waste management amongst professionals, researchers, government departments and local authorities.
