New paper in Ind. Eng. Chem. Res. Abstract: A correlation has been proposed for predicting local bed-to-surface heat transfer coefficients in conical spouted beds based on an experimental study conducted using beds made up of sand, sawdust, and their mixtures under various operating conditions, namely, different static bed heights and gas velocities over minimum spouting. A comparison...

One of our works in Green Chemistry is in the top 10% most downloaded papers of 2015: http://goo.gl/ovjgxS Green Chemistry, from the Royal Society of Chemistry (RSC), is one of the top journals (first quartile, Q1) in fields of Multidisciplinary Chemistry (16 out of 163) and Green & Sustainable Science & Technology (1 out of 29) with an Impact Factor of 8.506 (2015). You can...

Abstract: Equilibration of a Ni/La2O3–αAl2O3 catalyst has been studied with the aim of using it in ethanol steam reforming (ESR) under reaction–regeneration cycles. The runs have been performed in a fluidized bed reactor, with the reaction steps being carried out at 500 °C and 700 °C, with a steam/ethanol (S/E) molar ratio of 6 and low values of space time (from 0.001 to 0.06...

Abstract: The effect of the operating conditions (cofeeding methanol and water, temperature, space time, and feed concentration) on the reaction indices of the transformation of dimethyl ether (DME) to light olefins has been studied, using a HZSM-5 zeolite catalyst (SiO2/Al2O3 molar ratio of 280) agglomerated with boehmite and alumina. The experiments have been carried out in an...

Abstract: The kinetic behavior of the CuO–ZnO–ZrO2 (CZZr) and CuO–ZnO–MnO (CZMn) metallic functions in the methanol synthesis step has been studied under suitable operating conditions for DME synthesis, and the values of methanol yield and selectivity have been compared with those corresponding to the conventional CuO–ZnO–Al2O3 (CZA) metallic function. On the other hand, the performance...

Abstract: A kinetic model of 11 lumps (dimethyl ether, methanol, water, ethylene, propylene, butenes, C2–C4 paraffins, C5+ hydrocarbons, BTX aromatics, methane and CO) has been determined for the reaction of DME to olefins (DTO process) over a HZSM-5 zeolite catalyst (SiO2/Al2O3 = 280) agglomerated with boehmite. The experiments have been carried out under a slightly above than at 1.5 bar in...

La Universidad de Cantabria organiza el curso de "Valorización Química Sostenible de Dioxido de Carbono"  del 27 al 30 de Junio de este año. El desarrollo de nuevas tecnologías que permitan hacer frente a la demanda energética dela sociedad actual de una forma sostenible y compatible con el medio ambiente, está entre los grandes retos del siglo XXI. En este sentido, los procesos de...

Abstract: Biomass residue is one of the raw materials of most interest as a source of renewable energy. There are three major types of biomasses to obtain energy: lipids, sugars/starches and cellulose/lignocellulose. The estimate of the gross calorific value (PCS), whose determination methods require long periods and are relatively expensive, is crucial in the analysis and development of...

In our recent publication in Industrial & Engineering Chemistry Research journal (IEC), the main objective is to study the effect of the catalyst properties, particularly, matrix acidity and its properties, in the transformation of dimethyl ether (DME) to light olefins (DTO process). The catalysts used have been prepared by agglomerating HZSM-5 zeolite with a different SiO2/Al2O3 ratio...
