Time: October 25th, 2017, 9:30am
Venue: First floor Conference Room of No.1 Energy Building
Lecturer: Dr. Pablo Beato, Lead Scientist in Haldor Topsoe’s Atomic Scale Analysis Department
Pablo obtained the degree in Chemistry in 2001 from the Philipps University Marburg, Germany. For the PhD he moved to the Fritz-Haber-Institute in Berlin, Germany and completed his thesis in 2005 on the synthesis of Molybdenum oxide based catalysts for selective oxidation reactions of alkanes, under the supervision of Prof. Robert Schlögl.
Pablo joined Haldor Topsoe A/S, as a Research Scientist in 2005. In the following years, he worked on a number of project manager assignments, ranging from small to large scale internal and international projects, mainly in the area of zeolites and synfuel technologies. In 2010, he took over the responsibility for the optical spectroscopy laboratories at Haldor Topsoe's R&D, which is a job position he is still holding today. As the head of a group of technical and scientific staff he dedicates much of his time to the development of spectroscopic tools to obtain fundamental understanding of the synthesis and the working principles of heterogeneous catalysts. In 2011 he was appointed Senior Scientist and in 2017 Lead Scientist in Haldor Topsoe's Atomic Scale Analysis Department.
The combination of fundamental and applied science has always been important to him, which is reflected in the broad range of patents obtained, of which three are commercially exploited, and the more than 70 peer-reviewed research articles published.
His technical experiences cover refinery catalysts for hydrotreating and hydrocracking, syngas catalysts for reforming and methanation, catalysts for the synthesis of sulfuric acid and environmental catalysts, i.e. metal-containing zeolites for NH3-SCR and nanoporous materials for the methanol conversion to hydrocarbons.
The lecture will cover the most recent work published on the methanol to hydrocarbons (MTH) reaction by our group in the last two years (see references below). The main focus will be on mechanistic understanding of the MTH reaction and the deactivation behavior of different zeolite topologies.
