Improved high temperature oxidation behaviour of

Abstract Numerous studies have been undertaken during the last decade examining the potential of ion implantation to improve the high temperature oxidation behaviour of a range of metals and alloys. Most of these investigations have focussed on improved mechanistic understanding of the role of specific elements and, in particular, of the effect of the so-called reactive elements, such as

2021-3-12  The supported mixed metal oxide (MMO) sorbents were screened for high-temperature CO2 capture under CO2 rich (86% CO2) and lean (14% CO2) gas streams at 650 °C and atmospheric pressure. The MMO sorbents captured 53–63 wt % of CO2 per gram of sorbent under 86 and 14% CO2, accounting for about 98% carbonation efficiency, which outperforms the CO2 capture capacity of
