High‐Temperature Sulfur Removal from Biomass‐Derived Synthesis Gas over Bifunctional Molybdenum Catalysts

Abstract

In contrast to all other transition‐metal‐catalyzed hydrostannation reactions documented in the literature, the addition of Bu3SnH across various types of alkynes proceeds with excellent trans selectivity, provided the reaction is catalyzed by [Cp*Ru]‐based complexes. This method is distinguished by a broad substrate scope and a remarkable compatibility with functional groups, including various substituents that would neither survive under the conditions of established Lewis acid mediated trans hydrostannations nor withstand free‐radical reactions. In case of unsymmetrical alkynes, a cooperative effect between the proper catalyst and protic functionality in the substrate allows outstanding levels of regioselectivity to be secured as well.

Integrated Desulfurization and Methanation Concepts for SNG Production

“…This would allow simplifying the process even further by omitting high temperature gas cleaning that removes inorganic and organic sulfur species [37], while a highly active Ni or Ru based catalyst for methanation can be used.
