Chemically and Physically Pretreated Straw in Moderate Conditions: Poor Correlation between Biogas Production and Commonly Used Biomass Characterization

Shruthi Meenakshisundaram, Vincenzo Calcagno, Claire Ceballos, Antoine Fayeulle, Estelle Léonard, Virginie Herledan, Jean-Marc Krafft, Yannick Millot, Xiaojun Liu, Claude Jolivalt, André Pauss

Straw is a substantial agricultural by-product for biogas production. Hydrolysis of straw is found to be a rate-limiting step during its anaerobic digestion and could be enhanced by pretreatment. In this paper, the effect of various combinations of particle size reduction, autoclaving, and low-…

Relevant parameters for obtaining high-surface area materials by delamination of magadiite, a layered sodium silicate

Yunfei Bi, Jean-François Lambert, Yannick Millot, Sandra Casale, Juliette Blanchard, Shuangqin Zeng, Hong Nie, Dadong Li

Layered silicates can be used for the preparation of high surface area materials by intercalation with organic cations followed by ultrasonication. The relevant parameters for delamination (exfoliation) of cetyltrimethylammonium bromide exchange magadiite are investigated. Using a magadiite wet…

Photocatalytic Hydrogen Evolution Using Ni–Pd/TiO 2 : Correlation of Light Absorption, Charge-Carrier Dynamics, and Quantum Efficiency

Ana Luna, Diana Dragoe, Kunlei Wang, Patricia Beaunier, Ewa Kowalska, Bunsho Ohtani, Daniel Bahena Uribe, Miguel A. Valenzuela, Hynd Remita, Christophe Colbeau-Justin

TiO2 surface modification with bimetallic nano particles (NPs) has demonstrated to be a strategy to enhance the hydrogen generation via photocatalysis and to minimize the use of expensive noble metals. A better understanding of the role of bimetallic NPs is of crucial importance to design efficient…

Factors affecting the long-term stability of mesoporous nickel-based catalysts in combined steam and dry reforming of methane

K. Jabbour, N. El Hassan, A. Davidson, S. Casale, Pascale Massiani

An ordered mesoporous " one-pot " nickel-alumina catalyst (5 wt% Ni) was synthesized using the evaporation-induced self-assembly method. Compared to an impregnated and to a non-porous catalysts, the ordered "one-pot" Ni-alumina sample displayed, after in-situ reduction, the…

Influence of pretreatment and reaction conditions on the catalytic activity of HAlBEA and CoHAlBEA zeolites in vinyl chloride formation from 1,2-dichloroethane

Izabela Kamińska, Dmytro Lisovytskiy, Laetitia Valentin, Christophe Calers, Yannick Millot, Emil Kowalewski, Anna Śrębowata, Stanislaw Dzwigaj

HAlBEA and CoHAlBEA zeolite catalysts treated at 523 K or 873 K for 3 h in Ar, H2/Ar or air flows, respectively, were investigated in catalytic dehydrochlorination of 1,2-dichloroethane (DCE). The dehydrochlorination of DCE on these zeolite catalysts resulted in almost 100% selectivity to vinyl…
