Ring hydrogenation of naphthalene and 1-naphthol over supported metal catalysts in supercritical carbon dioxide solvent

Novel MoP/HY catalyst for the selective conversion of naphthalene to tetralin

“…However, the high cost and low abundance of these materials retard its commercial use. Transition metal catalysts such as Ni, Co, W metals supported on SiO 2 -Al 2 O 3 , ZrO 2 , TiO 2 or activated carbon [15][16][17][18][19][20] are adopted for the hydrogenation of naphthalene; however the development of novel materials for the enhancement in tetralin selectivity are needed.…”

The overall activity of transition metal phosphide catalysts in the simultaneous hydrodesulphurization of dibenzothiophene, hydrodenitrogenation of quinoline and deoxygenation of ethanol was in the order of Fe 2 P < Co 2 P < MoP < Ni 2 P [26-29].…”

Tiny Ruthenium‐Cobalt‐Cobalt Hydroxide Nanoparticles Supported on Graphene for Efficiently Catalyzing Naphthalene Complete Hydrogenation

“…Taking the hydrogenation of naphthalene as an example, the main products are tetralin, octahydronaphthalene and decalin, which have important applications in varnish remover, lubricants, dye, pesticide, pharmaceutical. Additionally, tetralin and decalin are often used as efficient solvents for dissolving grease, resin and rubber . Moreover, the redundant existence of arenes in transportation fuels brings environmental damage and the decrease of the cetane number of diesel fuel .…”

Charging a Liquid Organic Hydrogen Carrier System with H2/CO2 Gas Mixtures

“…successfully demonstrated the hydrogenation of cyclohexene in a continuous fixed‐bed reactor using a H 2 /CO 2 ‐ratio of 0.055 at 136 bar and 70 °C. The group of Shirai, studied the subcritical hydrogenation of naphthalene to decalin with a H 2 /CO 2 ‐ratio of 0.6 at 160 bar and 60 °C. They showed that carbon‐supported catalysts are more active than alumina‐supported catalysts.…”
