In order to achieve process intensification for adsorption chillers and heat pumps, a new composite material was developed based on sintered aluminum fibers from a melt-extraction process and a dense layer of silico-aluminophosphate (SAPO-34) on the fiber surfaces. The SAPO-34 layer was obtained through a partial support transformation (PST) process. Preparation of a composite sample is describ...

Nano-SAPO-34 molecular sieves synthesized in a microwave environment with 20 nm crystal size showed a longer lifetime than SAPO-34 prepared by the conventional hydrothermal method in the reaction of methanol to olefins. It has been found that silicon distribution strongly affects the lifetime and selectivity. Thus, silicon at the border of the silicon islands gives a higher lifetime and lower C...

Zeolites have found tremendous applications in the chemical industry. However, dynamic nature of their active sites under flow adsorbate molecules for adsorption and catalysis is unclear, especially operando conditions, which could be different from as-synthesized structures. In present study, we report a structural transformation adsorptive SAPO-34 zeolite by using acetone as probe molecule va...

•Cr2O3(SG)/H-SAPO-34 shows a C2=?C4= selectivity of 95.7% in CO2 hydrogenation •Ethene accounts for more than 74% light olefins with an E/P ratio reaching 3.1 •Ethanol is formed through the reaction H3CO? and H? on Cr2O3(SG) converted into ethene SAPO-34 leads to high Conversion effective strategy sustainable utilization fossil energy biomass. However, highly selective production specific olefi...

Methanol is a key reaction intermediate formed on MnO x that synergistically reacts with SAPO-34 to produce light olefins.
