Book excerpt: Bio-oil obtained by the fast pyrolysis of biomass has the potential to serve as source of alternative liquid fuel for both power generation and transportation fuel. Bio-oils are comprised of oxygenated compounds, due to the presence of a high percentage of these oxygenated groups bio-oil possesses negative properties such as low heating value, low volatility, thermal instability, corrosiveness, immiscibility with fossil fuels and a tendency to polymerize over time. Bio-oils have been converted to both boiler and transportation fuels in laboratory and demonstration projects. However, the available technologies have not proven commercially viable. Therefore, the main objective of this study is to develop additional, potentially commercializable, technologies to upgrade bio-oils and pretreated bio-oil by hydroprocessing pathways. Previous hydrodeoxygenation studies over nearly three decades have provided considerable information about methods to upgrade bio-oil by this technology. However, rapid catalyst deactivation and low yields continue to be problematic and further research is required to refine current hydrodeoxygenation methods and catalysts. In our study we are applying pretreatment to the bio-oil at ambient temperature and pressure conditions to hydroprocess pretreated bio-oil in a single-stage. An initial pretreatment was performed to convert aldehydes present in the bio-oil into carboxylic acids followed by a single-stage hydroprocessing, that was performed to produce hydrocarbons. Where appropriate, successful products produced from the hydroprocessing treatments were analyzed for acid value, oxygen content, heating value, elemental analysis, FTIR and GC-MS. Statistical analysis was performed by analysis of variance (ANOVA).

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.

Available in PDF, EPUB and Kindle. Book excerpt: Future predicted shortages in fossil fuel resources and environmental regulations from fossil fuel combustion have led to great research interest in developing alternatives to fossil fuels. Biomass-derived bio-oils will have the potential to replace conventional transportation fuels because of their sustainability and environmental advantages. However, the presence of high percentages of chemical oxygenates cause negative properties such as high water content, low volatility, lower heating value, corrosiveness, immiscibility with fossil fuels and instability during storage and transportation. Moreover, polymerization, esterification, condensation and other reactions occur between these highly reactive oxygenates in bio-oil (Diebold 2000). These negative properties hinder both bio-oil direct use as a fuel and the fuel conversion process (Mohan, et al. 2006). Hydrodeoxygenation has proven itself effective in converting of bio-oil to pure hydrocarbons. However, the large consumption of expensive hydrogen prevents the industrialization of bio-oil. Therefore, development of more efficient hydrodeoxygenation approaches with less capital cost will be desirable. The objective of this current research was to upgrade raw and distilled bio-oil by oxidation to a stabilized precursor to the final hydrocracking step of hydrodeoxygenation. In the second chapter, raw bio-oil, two pretreated bio-oils and hydrotreated bio-oil were hydrodeoxygenated to produce liquid hydrocarbons in the continuous reactor. In the third chapter, raw bio-oil, oxidized raw bio-oil, distilled bio-oil and oxidized distilled bio-oil were hydrodeoxygenated to liquid hydrocarbons with hydrogen in the batch reactor. In the fourth chapter, oxidized distilled bio-oil was hydrotreated with model syngas to organic liquid products followed by hydrocracking with hydrogen to produce liquid hydrocarbons. In the fifth chapter, oxidized distilled bio-oil was upgraded with syngas (H2/CO molar ratios of 4:6) in a single stage to produce organic liquid products. The resultant stabilities of these organic liquid products were investigated by application of accelerated aging. The research results showed that oxidized distilled bio-oil could be upgraded by the syngas in a single stage to produce stabilized bio-oil. This success will replace hydrogen by syngas for first stage hytrotreating and save shipping fee by transportation less weight of upgraded bio-oil rather than the bulky and high moisture content biomass.

Book excerpt: Biorefineries are becoming increasingly important in providing sustainable routes for chemical industry processes. The establishment of bio-economic models, based on biorefineries for the creation of innovative products with high added value, such as biochemicals and bioplastics, allows the development of “green chemistry” methods in synergy with traditional chemistry. This reduces the heavy dependence on imports and assists the development of economically and environmentally sustainable production processes, that accommodate the huge investments, research and innovation efforts. This book explores the most effective or promising catalytic processes for the conversion of biobased components into high added value products, as platform chemicals and intermediates. With a focus on heterogeneous catalysis, this book is ideal for researchers working in catalysis and in green chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: In chemical processes, the progressive deactivation of solid catalysts is a major economic concern and mastering their stability has become as essential as controlling their activity and selectivity. For these reasons, there is a strong motivation to understand the mechanisms leading to any loss in activity and/or selectivity and to find out the efficient preventive measures and regenerative solutions that open the way towards cheaper and cleaner processes. This book covers in a comprehensive way both the fundamental and applied aspects of solid catalyst deactivation and encompasses the state-of-the-art in the field of reactions catalyzed by zeolites. This particular choice is justified by the widespread use of molecular sieves in refining, petrochemicals and organic chemicals synthesis processes, by the large variety in the nature of their active sites (acid, base, acid-base, redox, bifunctional) and especially by their peculiar features, in terms of crystallinity, structural order and textural properties, which make them ideal models for heterogeneous catalysis. The aim of this book is to be a critical review in the field of zeolite deactivation and regeneration, by collecting a series of contributions by experts in the field which describe the factors, explain the techniques to study the causes and suggest methods to prevent (or limit) catalyst deactivation. At the same time, an anthology of commercial processes and exemplar cases provides the reader with theoretical insights and practical hints on the deactivation mechanisms and draws attention to the key role played by the loss of activity on process design and industrial practice.
