Project granted in the framework of HORIZON-CL4-2021-RESILIENCE-01-14
Fast-Response electrically heated catalytic reactor technology for CO2 reduction
Acronym: e-CODUCT
Abstract: The e-CODUCT project aims at electrifying the simultaneous chemical conversion acid gas components (CO2 and H2S) into the platform molecule CO and marketable sulphur using an electrothermal fluidised bed reactor (ETFB) technology. The corresponding process will comprise two steps: a first one for CO2 and H2S reduction into COS and a second step for COS decomposition into the platform molecule CO and Claus grade sulphur. To demonstrate its valorisation potential, CO will be converted into green methanol as final product using a third reaction. The e-CODUCT consortium is composed of nine entities including industrial and academic partners spanning a complete value chain from material suppliers and engineers to modelling experts and technology providers. e-CODUCT will optimise and scale-up the reactor materials and catalysts to TRL6 to 16t/y of CO production while reducing reactor size by 50%, among others via the removal of heating units. ….

2022: Valentin Valtchev (CNRS, France) is the recipient of the 2022 International Zeolite Association (IZA) award for his important contributions to the fundamental understanding of zeolite synthesis and post-synthesis modification of industrially-important zeolites.
Prof. Valtchev will act as the IZA Ambassador from now until the next International Zeolite Conference in 2025.
2016: Donald W. Breck Award – the highest recognition of the International Zeolite Association
2016: La Recherche 2016: Chimie Award, France
2014: Baron fon Cronstedt Award – the highest recognition of the Federation of European Zeolite Associations
2011: Breakthrough of 2011 according to the Editors of Science (9 place) for the work on the synthesis of ultra-small EMT type zeolite (Science 335 (2012) 70 – 73).
1991: Eureka Award – Bulgaria Young Inventor Award
Valentin Valtchev (CNRS, France) is the recipient of the 2022 International Zeolite Association (IZA) award for his important contributions to the fundamental understanding of zeolite synthesis and post-synthesis modification of industrially-important zeolites.
Donald W. Breck Award (2016)
The Donald Breck Award of the International Zeolite Association (IZA) is given every three years for outstanding contribution to zeolite science and practice and financially supported by UOP-Honeywell. The 2016 prize was given for “understanding the nucleation and growth in organic-free hydrogel systems leading to rational design of industrially relevant nanosized zeolites”.
Baron fon Cronstedt Award (2014)
The Baron fon Cronstedt Award of the Federation of European Zeolite Associations is given every three years for outstanding contribution to zeolite science at European level and financially supported by TOTAL. The prize was given for contributions to science and technology related with zeolites and other porous materials, fundamental studies on zeolite synthesis, that brought the current state of the art to the level of rational design of high quality nanosized zeolites.
Eureka Award (1991)
The Eureka Award is given by the Bulgarian Ministry of Industry to a Young Researcher for an invention with a strong industrial potential.
