Abstract

Hydrogen is essential in a variety of large-scale chemical processes. As a carbon-free energy carrier, hydrogen has a potential for wide use within power production and transportation. However, mos...

  • The Intergovernmental Panel on Climate Change (IPCC) reports, “Human activities are estimated to have caused approximately 1.0 °C of global warming above pre-industrial levels, with a likely range of 0.8−1.2 °C”.1,2 With growing concern of negative consequences of climate changes, major efforts have been initiated to head for a low-emission and sustainable future

  • In addition to deploying technologies for providing energy from renewable sources, it is widely accepted that decarbonizing power production, transport, and industrial processes coupled with carbon capture and storage (CCS) is important to reach the necessary and ambitious goals.[3]

  • In a conventional scheme for hydrogen production, natural gas is reformed and the produced synthesis gas is processed through two stages of water−gas shift units before the off-gas is cooled down to remove CO2 by a process utilizing solvents

Summary

Introduction

The Intergovernmental Panel on Climate Change (IPCC) reports, “Human activities are estimated to have caused approximately 1.0 °C of global warming above pre-industrial levels, with a likely range of 0.8−1.2 °C”.1,2 With growing concern of negative consequences of climate changes, major efforts have been initiated to head for a low-emission and sustainable future. The present work reports synthesis, characterization, and testing of K-promoted sorbents based on CoxMg3‐xAl hydrotalcites at conditions relevant for the SEWGS process.
