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.

Due to overconsumption of fossil carbon, humanity faces four major problems: global warming, decrease of biodiversity, pollution of the biosphere, and the degradation of agriculture soils. It is not enough to reduce our greenhouse gas emissions by stopping the consumption of fossil carbon; it is also urgent to remove carbon dioxide from the atmosphere. In order to understand the challenges outlined above, a minimal knowledge of the most important carbon compounds and their transformations is an asset. This textbook is therefore an introduction to the molecular sciences and shows how we depend on carbon compounds, what they are and how they are transformed.Plant biomass, including agricultural, forestry and urban wastes, is the source of bio-carbon that can replace fossil carbon. In addition, we will always need carbon-containing substances for our comfort and health. These important topics are covered in this textbook.Life begins with water, carbon dioxide, and the sun. Carbon dioxide is not a waste, but a starting material for a better life. Biomass and carbon dioxide are our best allies in sustainable development (circular economy). This textbook explains why.This book contains 100 problems and solutions; more than 180 colour pages; and bibliographical sketches of most important scientists and inventors.
