Catalytic co-aromatization of ethanol and methane, Applied Catalysis B: Environmental

 Illustration showing bioethanol being produced from biomass fermentation when effectively valorized into aromatics under the assistance of methane at mild conditions when Ag modified HZSM-5 catalyst is charged. In the upper right is Ethanol indicated with a dark green liquid teardrop and below that is a simple illustration of a forest. A yellow arrow surrounded by molecules leads to a large molecule indicated by interlinked, gold hexagon shapes that are formed into six circles with dark seven dark green spheres attached. Up above and to the right of this large molecule is the label Ag/ZSM-5. A yellow arrow leads to the lower right from the large molecule to a gold liquid teardrop surrounded by molecules and labeled Aromatics.

Pilot Scale Production of Mixed Alcohols from Wood, Industrial & Engineering Chemistry Research

Diagram of a continuously stirred tank reactor (CSTR). The diagram begins by showing process gas (10-20 MPa) going in to three cylindrical gas accumulators then to a pressure control valve and flow control valve where H2S + H2 enters. This then drops into the CSTR shown with a stir motor at the top and a catalyst basket and heater surrounding it. The diagram shows two areas of elimination: (1) gas sample for GC analysis leaving the CSTR and becoming waste gas and (2) product going through a condenser and leaving as waste gas or going through a chilled liquid collection area and going into liquid storage.

Initial reduction of the NiO(100) surface in hydrogenThe Journal of Chemical Physics

Curved line graph showing the identified minimum-energy pathway (solid curves) of H reduction of the ideal NiO(100) surface. The y-axis ranges from 0 to 2.5 and a series of illustrations within the graph are labeled in states from 1 to 4. There are two curved blue lines; the dotted curved line shows a single arc reaching to 2.41 as it goes left to right; the solid line shows to arcs within the dotted arc (at 1.78 and 1.86) and a third shorter arc to the right at 1.25. State 1, the initial state, is the ideal surface with two H2 molecules adsorbed on two Ni sites and starts at a baseline of 0. In state 2 (at .8, the lower point in between the two solid blue arches), one of the two adsorbed H2 molecules dissociates and an H-H pair is formed. A light blue arrow points at Step 2 from a 3-layer, blue and red tinker-toy shaped cube with two white pegs and balls sticking out from the top. The atomic structure of state 3 (at .92, the lower point before the solid blue arc) is shown in the lower inset indicated by a light blue arrow from the number 3 to a 3-layer, blue and red tinker-toy shaped cube with two white pegs and balls and one red/white peg and ball sticking out from the top. The structure of the final state 4 (at .78 has a light blue arrow pointing to it from a single-layer blue and red tinker-toy shaped square with four white and one pink ball sticking out from the center. The dashed curve shows a direct reaction from 1 to 3 without pre-dissociation of the first H2 molecule.
