Development of Modified Zeolites for Methane Separation from Diluted Streams

Inorganics
Methane (CH4) is the second-largest contributor to climate change after carbon dioxide (CO2) and has a global warming potential about 72 times greater than CO2 over a 20-year timescale.

Toward Minimal Complexity Models of Membrane Reactors for Hydrogen Production

Membranes, 2022
Membrane reactors are inherently two-dimensional systems that require complex models for an accurate description of the different transport phenomena involved. However, when their performance is limited by mass transport within the reactor rather than by

Catalytic reactors with membrane separation

, 2015
The combination of membrane separation and catalytic reactors in the so-called membrane reactor concept provides a high degree of process integration that results in substantial process intensification. In particular, combining perovskite-based membranes

Development and Proof of Concept of a Compact Metallic Reactor for MIEC Ceramic Membranes

Membranes, 2021
The integration of mixed ionic–electronic conducting separation membranes in catalytic membrane reactors can yield more environmentally safe and economically efficient processes. Concentration polarization effects are observed in these types of membranes

An Enhanced Sherwood Number to Model the Hydrogen Transport in Membrane Steam Reformers

Membranes, 2021
It is well known that membrane reactors are inherently two-dimensional systems in which species concentrations vary as a consequence of both the reaction and permeation across the membrane, which occurs in the direction perpendicular to that of the main ...

Stability of pore-plated membranes for hydrogen production in fluidized-bed membrane reactors [PDF]

, 2020
\u3cp\u3ePd-based membranes prepared by pore-plating technique have been investigated for the first time under fluidization conditions. A palladium thickness around 20 μm was achieved onto an oxidized porous stainless steel support.

Development of CVD Silica Membranes Having High Hydrogen Permeance and Steam Durability and a Membrane Reactor for a Water Gas Shift Reaction

Membranes, 2019
Water gas shift reaction of carbon monoxide (CO) with membrane reactors should be a promising method for hydrogen mass-production because of its high CO conversion, high hydrogen purity and low carbon dioxide emission.

Investigation of thermal effects and transient reactor profiles in a plasma-sorbent system for simultaneous CO2 capture and conversion

Journal of CO2 Utilization
CO2 capture and utilisation (CCU) is a promising solution to mitigate greenhouse gas emissions and has received much attention recently. Usually, CO2 is captured and utilised in two separate processes. In this work, we focus on integrating both processes
