This book was released on 2020-12-02 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomass is widely considered as a potential alternative to dwindling fossil fuel reserves. There is a large variety of biomass sources (oleaginous, lignocellulosic, algae, etc.), with many possible conversion routes and products. Currently, biomass is not just viewed as a source of biofuels, but also as an interesting feedstock for the production of bio-based chemicals that could largely replace petrochemicals. In this context, the search for new sustainable and efficient alternatives to fossil sources is gaining increasing relevance within the chemical industry. There, the role of catalysis is often critical for the development of clean and sustainable processes, aiming to produce commodity chemicals or liquid fuels with a high efficiency and atom economy. This book gathers works at the cutting edge of investigation in the application of catalysis, for the sustainable conversion of biomass into biofuels and bio-based chemicals.

Download or read book Valorization of Biomass Using Novel Catalytic and Electrocatalytic Processes written by Manali Dhawan and published by . This book was released on 2021 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing energy requirements and environmental pollution, along with predicted shortages of fossil fuels in the near future, have accelerated the search for alternative renewable energy sources. Biomass is a promising renewable resource for the production of value-added fuels and chemicals. In this work, triglycerides, furfural and 5-hydroxymethylfurfural (HMF) are used as bio-derived feedstock chemicals for chemo- or electro-catalytic conversion to valuable chemicals that find applications in fuels, polymer, perfumery and pharmaceutical industries.Chemical interesterification of triglycerides was conducted with methyl acetate, as an alternative to transesterification, to co-produce biodiesel and a higher value-added compound, triacetin, instead of glycerol. Conversion of waste methyl acetate in terephthalic acid production industry using triglyceride into two valorized products biodiesel and triacetin is a novel idea. Biodiesel is a well-known renewable fuel and triacetin can be used as a fuel additive. Amongst various base catalysts screened, calcined Mg-Al hydrotalcite (Mg:Al mole ratio - 3:1) was found to have the best activity in terms triglyceride conversion and triacetin selectivity.We also studied the etherification of HMF with ethylene glycol to produce 5-(2- hydroxyethoxymethyl) furfural (HEMF), which finds application as a fuel additive. Metal substituted heteropoly acid catalysts were identified as a chemo-selective catalyst that favored etherification of HMF over acetalization reaction. Aluminum substituted dodecatungsto-phosphoric acid achieved the highest HMF conversion and HEMF selectivity, which was attributed to the combined role of the catalyst's Lewis and Bronsted acidity.Further, electrocatalytic hydrogenation (ECH) of furfural using zinc as a novel metal catalyst was studied to produce furfuryl alcohol and 2-methylfuran, which have applications in pharmaceutical, polymer and fuel industries. The effect of metal catalyst and electrolyte pH on the yield and Faradaic efficiency (FE) of the desired products was studied. Electrolysis at neutral pH (pH 6 to 8) exhibited increased yields and FE as compared to acidic and basic pH. FE for ECH of furfural with Zn was remarkably higher as compared to Cu and Ni.However, during ECH of furfural, the total yield of the desired products was low compared to the conversion of furfural which was due to electrodimerization reactions. Thus, zinc metal nanoparticles were synthesized by electrodeposition to achieve higher activity for furfural ECH as compared to bare zinc metal due to high surface area and roughness. Furfural electrolysis in 0.5 M bicarbonate electrolyte at -0.6 V/RHE yielded higher conversion, yield and FE as compared to bare zinc. Catalyst characterization revealed the presence of surface zinc oxide species post- electrolysis, which could have a role in reaction mechanism.Overall, this work contributes to the field of biomass valorization, by identifying new selective catalysts and processes to produce value-added chemicals using renewable bio-derived feedstocks. Catalyst synthesis, reaction engineering and process optimization studied for biomass conversion processes in this work will aid in future process intensification of such processes.

Download or read book Aqueous phase Catalytic Conversions of Renewable Feedstocks for Sustainable Biorefineries written by Georgios Papadogianakis and published by Frontiers Media SA. This book was released on 2024-08-23 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, there is growing interest in aqueous-phase catalytic conversions for the valorization of renewable biomass-based feedstocks for biorefineries to produce, in a sustainable way, biofuels, chemicals, power, energy, materials, pharmaceuticals and food. This is because of the highly polar nature of water which makes it an ideal medium to convert polar biomass-based lignocellulose (cellulose, hemicellulose, lignin), with high oxygen content, and their upgraded products such as hydrophilic carbohydrates, platform chemicals and their derivatives. Another reason which makes water the solvent of choice is that water itself is involved either as a reagent or as a byproduct even in large amounts in typical conversions for the valorization of biomass. The obtained intermediates further react in the aqueous medium, often without any separation and purification, to manufacture more valuable products. This results in substantial energy savings, lower emissions and economic benefits. Furthermore, water could act as a catalyst in conversions of biomass-based feedstocks such as in liquefaction reactions under subcritical conditions. Moreover, novel types of catalytic reactivity have been observed in the aqueous solvent, not only with water-soluble transition metal catalytic complexes, but also with conventional heterogeneous catalysts and catalytic nanoparticles in a broad spectrum of different reactions such as, inter alia, aldol condensations and hydrogenation reactions. For example, in the aqueous-phase hydrogenation of the biomass-based key platform chemical levulinic acid into γ-valerolactone and beyond, employing heterogeneous catalysts and nanoparticles the presence of water has a beneficial effect and accelerates the reaction rates, whereas in organic solvents much lower activities were observed. This promotional effect of water in the hydrogenation of levulinic acid was proved by many experimental and theoretical studies using a broad spectrum of different types of catalytic systems.

Download or read book Catalysis by Precious Metals Past and Future written by Marcela Martinez Tejada and published by MDPI. This book was released on 2020-04-15 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The future of the precious metals is shiny and resistant. Although expensive and potentially replaceable by transition metal catalysts, precious metal implementation in research and industry shows potential. These metals catalyze oxidation and hydrogenation due to their dissociative behavior toward hydrogen and oxygen, dehydrogenation, isomerization, and aromatization, etc. The precious metal catalysts, especially platinum-based catalysts, are involved in a variety of industrial processes. Examples include Pt–Rh gauze for nitric acid production, the Pt/Al2O3 catalyst for cyclohexane and propylene production, and Pd/Al2O3 catalysts for petrochemical hydropurification reactions, etc. A quick search of the number of published articles in the last five years containing a combination of corresponding “metals” (Pt, Pd, Ru, Rh and Au) and “catalysts” as keywords indicates the importance of the Pt catalysts, but also the continuous increase in the contribution of Pd and Au. This Special Issue reveals the importance of precious metals in catalysis and focuses on mono- and bi-metallic formulations of any supported precious metals and their promotional catalytic effect of other transition metals. The application of precious metals in diverse reactions, either homogeneous or heterogeneous, and studies of the preparation, characterization, and applications of the supported precious metal catalysts, are presented.
