Ultrasound proves to be an effective technique for intensifying a wide range of processes
involving solids and, as such, is often used to improve control over both solids formation and …

Hydrogen, one of the most promising energy carriers for the future, is currently produced
mainly by natural gas reforming or coal gasification, where mixtures containing H2, CO2 and …

Abstract All-silica Decadodecasil 3 R (DD3R) zeolite membranes, possessing small pore
size of 0.36 nm× 0.44 nm, have been attractive in CO 2 removal from natural gas. In this …

All-silica DDR zeolite membrane has great potential for CO 2-CH 4 separation because of its
suitable pore size, great stability and insensitivity to moisture. However, the long synthesis …

DDR-type zeolite membrane was synthesized on porous α-alumina substrate by
hydrothermal treatment of a ball-milled Sigmal-1 crystal seed layer in an aluminum-free …

There have been significant advancements in small-pore zeolite membranes in recent
years. With pore size closely related to many energy-or environment-related gas molecules …

Biogas is an environmentally friendly and sustainable energy resource that can substitute or
complement conventional fossil fuels. For practical uses, biogas upgrading, mainly through …

Compared with other small pore zeolite membranes, all-silica DDR membrane has unique
advantages like smaller pore size and outstanding stability, which makes it perfect for the …

With the pressing concern of the climate change, hydrogen will undoubtedly play an
essential role in the future to accelerate the way out from fossil fuel‐based economy. In this …

The separation performances of all-silica DDR membranes are inferior to other small pore
zeolite membranes, which is the result of poor understanding of the corresponding zeolite …
