A new two-component (composite) water sorbent MgSO4/Hydroxyapatite has been developed for sorption-based solar heat storage. The matrix of the composite is a hydroxyapatite (HAP) material with ordered structure, high surface area 111.3 m2/g and mesopore dimensions centered at 45 nm. composites, prepared by wet-impregnation HAP MgSO4, have lower specific similar as matrix. maximum sorption capac...

For plastic waste cracking the path for production of high olefins yield without loose in gasoline fraction is an intriguing option. Among commercial FAU zeolites different properties and mesoporous HAlMCM-48 materials, catalysts polypropylene (PP) being able to operate low-temperature regime was searched. The aim investigate effects presence mesopore system context internal external acidic fea...

Nitrogen adsorption experiments have been extensively applied to shale pore structure research and evaluation. The can be quantitatively characterized in accordance with the nitrogen adsorption–desorption isotherm using various calculation models, whereas results obtained different models more effectively indicate characteristics of remains unclear. Further, there has not any unified process op...

Pharmaceutical products (PPs) are considered as emerging micropollutans in wastewaters, river and seawaters, sediments. The biodegradation of PPs, such ciprofloxacin, amoxicillin, sulfamethoxazole, tetracycline by enzymes aqueous solution was investigated. Laccase from Trametes versicolor immobilized on silica monoliths with hierarchical meso-/macropores. Different methods enzyme immobilization...

To increase the added value of corn stalk and improve performance biochar, magnesium chloride (MgCl2) was used to modify effects temperature on structure properties modified biochar were considered. With temperature, yield decreased. There a marked in number mesopores micropores, but mesopore pore diameter changed smaller diameter, specific surface area remarkably increased. As increased, conte...

Clays and clay rocks are considered good natural engineered barriers for deep geological disposal of nuclear waste worldwide. Metal corrosion organic degradation in underground repositories generate significant amounts gas that should be able to migrate through the multibarrier system avoid potential pressure buildup, which could compromising integrity host rocks. The is expected accumulate lar...

Ordered mesoporous silicas are widely used in separation science and catalysis, however, their slow batch synthesis is a barrier to scale-up new applications. SBA-15 one of the most extensively studied commercially available silicas, whose textural properties can be readily tuned through judicious choice conditions. Here we demonstrate continuous flow high yield at 80 °C using simple tube react...
