TL;DR: In this article, a large-scale production of pure carbon spheres, with diameters from 50nm to 1μm, has been achieved via direct pyrolysis of a wide range of hydrocarbons, including styrene, toluene, benzene, hexane, cyclohexane and ethene, in the absence of catalyst.

TL;DR: In this paper, the authors compared biochar production conditions to the yield and properties of biochar, particularly its long-term stability, and found that the yield of stable biochar fraction is nearly independent of the temperature.

TL;DR: Most biochars exhibited attractive acid-base interactions that impeded their transport, whereas the biochar with the greatest mobility had repulsive acid- base interaction, and greater retention of the MPs than that of the NPs was in contrast with the XDLVO predictions.
Abstract: Land application of biochar is increasingly being considered for potential agronomic and environmental benefits, e.g., enhancing carbon sequestration, nutrient retention, water holding capacity, and crop productivity; and reducing greenhouse gas emissions and bioavailability of environmental contaminants. However, little is known about the transport of biochar particles in the aqueous environment, which represents a critical knowledge gap because biochar particles can facilitate the transport of adsorbed contaminants. In this study, column experiments were conducted to investigate biochar particle transport and retention in water-saturated quartz sand. Specific factors considered included biochar feedstocks (wheat straw and pine needle), pyrolysis temperature (350 and 550 °C), and particle size (micrometer-particle (MP) and nanoparticle (NP)). Greater mobility was observed for the biochars of lower pyrolysis temperatures and smaller particle sizes. Extended Derjaguin–Landau–Verwey–Overbeek (XDLVO) calcula...

TL;DR: In this paper, pine cone was co-pyrolyzed with synthetic polymers (PE, PP and PS) in order to investigate the effect of biomass and plastic nature on the product yields and quality of pyrolysis oils and chars.

TL;DR: In this paper, the Hamburg process was used for feedstock recycling of poly(methyl methacrylate) (PMMA) in a fluidized bed, and the influence of fillers on the monomer yield has been studied.
