Benzene, mostly produced from fossil fuel sources, is an essential chemical to many modern industries. Alternatively non-renewable methods currently used, the present work explores using fast pyrolysis biomass-derived bio-oils furnish this valuable platform molecule. Notably, we report for first time impact of different operational parameters on highly selective continuous catalytic hydrodeoxygenation guaiacol, a bio-oil model compound, into benzene Mo2C/CNF-based catalyst. The parametric...
Highly performing activated biochar-based catalysts were produced for steam reforming of slow pyrolysis oil. The raw biochar obtained from the step was physically with CO2 at 700 °C and 1.0 MPa then employed as support. Preliminary tests on acetic acid 600 showed that using biochar-supported containing 10 wt % Ni 7 Co led to a conversion above 90% relatively deactivation rate. When representative organic model compounds mixture used feed, fast catalyst observed, probably due adsorption heavy...
Biochar addition to soil can lead potential environmental risks due its content of polycyclic aromatic hydrocarbons (PAHs). Until now, previous research focused on assessing the influence pyrolysis peak temperature and feedstock formation evolution PAHs. Nevertheless, effects other important process parameters —such as pressure, gas residence time, type carrier gas— have not been comprehensively explored. To fill this gap, a 2-level full factorial design experiments was conducted assess...
Chalcopyrite is the resource with highest amount of Cu content representing around 70–80% known reserves in world. However, chalcopyrite like other copper sulfides, usually found deposits grades 0.4–0.5% copper. The exploitation these using traditional flotation methods followed by pyrometallurgical treatment concentrate at limit economic viability. Hydrometallurgical route would be more suitable for treating low-graded sulfide ores. refractory ferric/sulfuric acid media and shows slow...
The present study aims at evaluating the suitability of producing activated carbons (ACs) derived from wheat straw by a one-step synthesis approach, as an alternative to more conventional two steps production processes (i.e., pyrolysis and subsequent activation). performance produced ACs, in one or steps, sustainable selective CO2 adsorbents for CH4/CO2 separation is compared. In addition, influence conditions on properties resulting two-step ACs carefully analyzed. We show that...
Ceria- and urea-doped activated biochars were used as support for Ni-based catalysts CO2 methanation purposes. Different materials prepared tested to find the best catalytic formulation. After several experiments—carried out at 0.35–1.0 MPa 300–500 °C—it was found that most suitable catalyst a wheat-straw-derived biochar loaded with 30 wt.% of CeO2 20 Ni. Using this catalyst, conversion 65% CH4 selectivity 95% reached 1.0 MPa, 400 °C, 13,200 h−1. From study influence gas hourly space...
In this work, different biochar-based metal catalysts were tested for mid-temperature (400−600 °C) acetic acid steam reforming. K, Co, Ce, Fe and Ni chosen as active phases the production of studied catalysts. Their performance was evaluated in terms conversion, hydrogen yield, acetone stability. The best outcomes obtained nickel-based catalysts, which exhibited high conversion (>90%) along with insignificant deactivation rates. Nevertheless, relatively low nickel loadings, a certain extent...
The present study aims at evaluating the performance of wheat straw-derived activated carbons (ACs) produced by two-step (pyrolysis + CO2 activation 800 °C) or one-step physical activation, with objective using them as sustainable adsorbents for CH4/CO2 separation. In addition, influence pyrolysis conditions on properties resulting ACs has been carefully analyzed. most important findings reported in this work showed that biochar-based precursors presenting best textural were obtained under...
The aim of this work is to test the capacity a biochar-based porous material enhance cracking pyrolysis vapors. Biochar sustainable obtained from renewable resources and relatively low cost alternative metal-containing catalysts used in catalytic cracking.
A deep study on the effects of absolute pressure, peak temperature, gas residence time and atmosphere pyrolysis behaviour wheat straw pellets in a bench-scale fixed-bed reactor has been carried out.
Nine wheat straw-derived biochars were produced under different pyrolysis conditions (i.e. peak temperature, absolute pressure, and atmosphere) subsequentially activated with CO2 at 800 °C in order to study the influence of operating on textural properties resulting biochars.
