Zeolite Rho: a highly selective adsorbent for CO2/CH4 separation induced by a structural phase modification

[EN] Zeolite Rho is able to successfully separate CO2 from CH4 with the highest selectivity ever observed on the basis of pore diameter and surface polarity. The adsorption of CO2 provokes structural changes in the zeolite Rho.We acknowledge financial support from Spanish CICYT (MAT2009-14528-C02-01, CTQ2010-17988/PPQ) and European Project TopCombi (NMP2-CT2005-515792).

ITQ-69: A Germanium-Containing Zeolite and its Synthesis, Structure Determination, and Adsorption Properties

"This is the peer reviewed version of the following article:ITQ-69: A Germanium-Containing Zeolite and its Synthesis, Structure Determination, and Adsorption Properties, which has been published in final form at https://doi.org/10.1002/anie.202100822. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving."[EN] In this work, a new zeolite named as ITQ-69, has been synthesized, characterized and its application as selective adsorbent for industrially relevant light olefins/paraffins separations has been assessed. This material has been obtained as pure germania as well as silica-germania zeolites with different Si/Ge ratios using a diquaternary ammonium cation as organic structure directing agent. Its structure was determined by single-crystal X-Ray diffraction showing a triclinic unit cell forming a tridirectional small pore channel system (8x8x8R). Also, it has been found that Si preferentially occupies some special T sites of the structure as deduced from Rietveld analysis of the powder X-ray diffraction patterns. In addition, the new zeolite ITQ-69 has been found to be stable upon calcination and thus, its adsorption properties were evaluated, showing a promising kinetic selectivity for light olefin separations in the C3 fraction.The authors acknowledge the Spanish Ministry of Science, Innovation and Universities (MCIU) for their funding via project RTI2018-101784-B-I00 and Program Severo Ochoa SEV-2016-0683.

W and Mo doped TiO2: Synthesis, characterization and photocatalytic activity

W-doped TiO2 and Mo-doped TiO2 photocatalysts were synthesized by EISA method and were characterized by different techniques. The photoactivity of these materials was evaluated by the degradation of 4- chlorophenol without oxygen supply. The catalysts exhibited only anatase crystalline phase and high specific surface areas of about 179 m2 g 1. The amount of dopant cations in TiO2 was a key parameter to increase the photoactivity. The results obtained show that with low dopant concentrations the degradation is improved, and this can be attributed to an increase in the lifetime of the photogenerated charges due to that dopant cations may easily trap electrons decreasing the recombination rate. Doped photocatalysts degraded 95% of 4CP, three times faster than Degussa P25. 69% reduction of total organic carbon (TOC) content was achieved by 1 wt.% W-doping

CFD Analysis of Bed Textural Characteristics on TBR Behavior: Kinetics, Scaling-up, Multiscale Analysis and Wall Effects

A simulation of a trickle bed reactor aided by computational fluid dynamics was implemented. With a Eulerian approach, geometrical characteristics were explicitly considered and two simultaneous heterogeneous reactions were included, hydrodesulphurization (HDS) and hydrodenitrogenation (HDN). This was performed in order to achieve the following: (1) attain further insight into a proper scaling‐up procedure to be able to obtain the same hydrodynamics and kinetics behavior in two reactors of different length and diameter scales; (2) develop a multiscale analysis regarding the communication of information between scales through the construction of a porous microstructure model from which the geometrical information of the microscale is captured by the effective transport coefficients (which affect the overall reactor behavior); (3) investigate the effect of operation conditions variations on hydrodynamics and kinetics; (4) and assess the deviations and further differences observed from average to punctual conversion values and the assumptions from kinetic literature models through a preliminary multiscale analysis. The CFD results were validated against experimental pressure drops data as well as HDS and HDN conversions theoretical data. An excellent agreement was found. The model produces a significant improvement in hydrodynamic parameters prediction, achieving 5 times better accuracy in predicting pressure drops and 50% improvement in holdup prediction. The fully coupled model predicts HDS conversion with 96% accuracy and HDN conversion with 94% accuracy. Results suggest that the best way to obtain similar kinetic and hydrodynamic behavior in TBRs with different length and diameter length scales is by equaling the liquid holdup (εγ) or the mass velocities (L‐G)

Influence of tillage on soil surface roughness structure andsurface porosity.

Soil erosion is a complex phenomenon involving the detachment and transport of soil particles, storage and runoff of rainwater, and infiltration. The relative magnitude and importance of these processes depends on several factors being one of them surface microtopography, usually quantified trough soil surface roughness (SSR). Surface soil porosity and SSR can be altered by tillage operation. Even though the surface porosity is an important parameter of a tilled field, however, no practical technique for rapid and non-contact measurement of surface porosity has been developed yet
