A biochar-based catalyst was successfully prepared by sulfonation of pyrolysis char with fuming sulphuric acid. Prepared catalyst was studied for its ability to catalyze transesterification of vegetable oils (i.e., Canola Oil) and esterification of free fatty acids (i.e., oleic acid) using methanol. Thus far, biochar-based catalyst has shown significant activity,>90% conversion, in esterification of FFAs while indicating limited activity for transesterification of triglyceride-based oils such as Canola Oil. The first step in catalyst development approach was to increase the transesterification activity through employing a stronger sulfonation procedure. The total acid density of the biochar-based catalyst increased by ~90 times resulting in significantly increased transesterification yield (i.e., from being almost negligible to ~9%). Further investigations on the biochar-based catalyst were conducted to determine the effect of sulfonation time (5 and 15 h) and surface area on the transesterification reaction. Two established activation techniques (i.e., chemical activation with KOH and the silica template method) have been utilized to develop the surface area and porosity of the biochar supports. The surface area of the biochar support increased from a typical 0.2 m2/g to over 600 m2/g. In the chemical activation method with KOH, the effect of activation temperature on the transesterification yield has been investigated. Three biochar-based catalysts with activated supports at three different temperatures (450, 675 and 875C) were prepared and compared for transesterification activity. The sulfonated catalysts were characterized using the following analyses: BET surface area, elemental analysis, total acid density, Fourier Transform Infra-Red (FT-IR) spectroscopy, and X-Ray Diffraction iii (XRD) spectroscopy. The catalyst supported on biochar activated at 675C resulted the maximum transesterification yield (18.9%). The reaction yield was dependent on both catalyst s.

This book helps the readers get a holistic understanding of the emergence of biochar-nanocomposite research. The low and long-term exposure of persistent hazardous pollutants in environment is well known for damaging the water, soil, sediments, and living biota. Thus, it is a crucial step to eliminate these pollutants from environment regimes to prevent the on-site destruction or the transfer into the food chain. Biochar is a carbon-rich solid material generated through pyrolysis of biomass, and currently, it is covering the hotspot in environmental management of pollutants. It is being utilized for the efficient immobilization and sorption of organic pollutants, heavy metals, dyes, improvement of soil redox conditions, aggregate stabilization, photocatalytic degradation, and for carbon sequestration. The fascinating properties like surface area, porous structures, functional groups, and mineral components turn it into suitable candidate for the removal of various class of pollutants from environmental matrices. Different reactions like sorption, reduction, precipitation, solidification, and degradation are mainly responsible for the effective cleaning of xenobiotics from environment through biochar application. However, rapidly evolving contaminants in the environment have made the remediation more complex, expensive, and challenging. In view of these aspects, the modification of biochar through the doping of nanometals/metal oxides/surfactants/ or chemical entities will result in modified biochar with high surface area, more functional entities, improved physical, chemical, thermal, and mechanical characteristics with more adsorptive sites. Inclusion of these exclusive properties can be done through magnetic modification, impregnation of nanometals/ metal oxides/surfactants, amination, acid/base reactions, steam activation, etc. The resulted biochar-based nanocomposites have demonstrated a vital role in remediation of persistent organic pollutants, radionuclei, and heavy metals through the various interaction mechanisms like surface complexation, π–π interaction, electrostatic interaction, hydrogen bonding, Fenton process, and photocatalytic degradation. Currently, advanced research work has been carried out for the designing of modified composites of biochar to achieve maximum removal efficiency, reusability, biotoxicity, and sustainability. Hence, for selective removal of pollutants through designed biochar surface with the focused experimentation toward optimization of feedstocks, process variables, appropriate impregnation of nanomaterials, interaction with secondary pollutants, physical environment, longevity, and regeneration will definitely pave the way for safe and commercial application of biochar-based nanocomposites.

The use of solid catalysts for the upgrade of renewable sources gives the opportunity to combine the two main cores of green chemistry, that is, on the one hand, the set-up of sustainable processes and, on the other, the use of biomass-derived materials. Solid catalysts have taken on a leading role in traditional petrochemical processes and could represent a key tool in new biorefinery-driven technologies. This book will cover topics related to the preparation and use of heterogeneous catalytic systems for the transformation of renewable sources, as well as of materials deriving from agro-industrial wastes and by-products. At the same time, the ever-increasing importance of bioproducts, due to the acceptance and request of consumers, makes the upgrade of biomass into chemicals and materials not only an environmental issue, but also an economical advantage.

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.
