Effects of metal dusting relevant exposures of alloy 601 surfaces on carbon formation and oxide development
Guo, Xiaoyang; Vanhaecke, Estelle Marie M.; Vullum, Per Erik; Ma, Jianyu; Panditha Vidana, Daham Sanjaya Gunawardana; Walmsley, John; Chen, De; Venvik, Hilde Johnsen (Peer reviewed; Journal article, 2020)Ni and Fe are excellent catalysts for carbon formation, and industrial alloys are therefore susceptible to metal dusting corrosion; a costly issue in e.g. synthesis gas manufacture. The objective of this work is to better ... -
High-temperature desulfurization of biomassderived synthesis gas using solid sorbents
Ma, Jianyu (Doctoral theses at NTNU;2021:14, Doctoral thesis, 2021)Conversion of synthesis gas from biomass gasification to fuels or other valuable chemicals is regarded as a sustainable and renewable pathway to solve the energy crisis. However, the sulfur impurities, normally in the form ... -
High-temperature sulfur capture by a Mn-Mo sorbent: An investigation of regeneration conditions and SO<inf>2</inf> formation and prevention
Ma, Jianyu; Mahmoodinia, Mehdi; Rout, Kumar Ranjan; Blekkan, Edd Anders (Peer reviewed; Journal article, 2023)The regeneration performance of a solid sorbent (alumina-supported 15Mn8Mo) for sulfur capture at high temperature has been studied. The regeneration of the sulfided sorbent was performed by oxidizing at different temperatures ... -
The Impact of Operating Parameters on the Gas-Phase Sulfur Concentration after High Temperature Sulfur Sorption on a Supported Mo-Mn Sorbent
Ma, Jianyu; Mahmoodinia, Mehdi; Rout, Kumar Ranjan; Blekkan, Edd Anders (Journal article; Peer reviewed, 2021)The impact of operating parameters on H2S capture from a syngas mixture by a Mo-promoted Mn-based high-temperature sorbent was investigated. The parameters investigated included temperature, space velocity, H2S concentration ... -
Investigations of molybdenum-promoted manganese-based solid sorbents for H2S capture
Ma, Jianyu; Rout, Kumar Ranjan; Sauer, Maximilian; Mahmoodinia, Mehdi; Blekkan, Edd Anders (Peer reviewed; Journal article, 2020)The promotion effect of Mo-addition to alumina-supported Mn-based sorbents for high-temperature desulphurization was explored. A series of Mn-based sorbents with fixed Mn-loading and different Mo-loadings were prepared by ... -
Regenerable Sorbents for High-Temperature Desulfurization of Syngas from Biomass Gasification
Ma, Jianyu; Mahmoodinia, Mehdi; Rout, Kumar Ranjan; Blekkan, Edd A. (Peer reviewed; Journal article, 2021)Single-metal high-temperature solid sorbents for syngas cleaning using Mn, Ca, Fe, Cu, or Mo supported on γ-Al2O3 were synthesized, characterized, and tested in a fixed-bed reactor. H2S and SO2 concentrations in the gas ... -
Sorbents for Sulfur Removal From Biomass-derived Syngas
Stavnes, Siri (Master thesis, 2018)The rising concern of global warming and emission of greenhouse gases have increased the demand for sustainable resources. Biomass is carbon neutral and a renewable energy source, thus a promising alternative to produce ... -
Study on initial stage of metal dusting corrosive on Inconel 601 and Incoloy 800
Ma, Jianyu (Master thesis, 2017)Metal dusting is a corrosive phenomenon of metals or alloys into fine, dust-like particles. It can be found in many industrial units or processes, such as petrochemical industry. Metal dusting is initiated by unwanted ...
