Decahydronaphthalene CAS 91-17-8 Decalin

The conversion of decalin increased with increasing temperature. It increases with the increase of catalyst pore size, and the B acid site of the catalyst plays a crucial role in the isomerization and ring-opening reactions of decalin. Y-type molecular sieves show a good type-selective effect on the catalytic cracking of decalin. At present, there are relatively few studies on the catalytic cracking of decalin, and the breadth and depth of research need to be improved. The extensive application of computational chemistry can help to better understand the rules of decalin catalytic cracking reaction, so as to better guide the development of corresponding catalysts and the optimization of process conditions.

Since the dehydrogenation reaction of decalin provides a considerable amount of H2, at 280 °C, the hydrogen supply capacity of this reaction can fully meet the needs of general vehicle fuel cells. In addition, under the experimental conditions, the effective mass hydrogen supply of this reaction was 7.3% (w), and the hydrogen supply per unit volume was as high as 64.8 kg/m3, which was higher than the effective mass hydrogen supply proposed by the U.S. Department of Energy (6.5% (w). )) and standard requirements for hydrogen supply per unit volume (62.0 kg/m3). As a hydrogen storage material, hydronaphthalene has the strongest hydrogen supply ability. In addition, from the perspective of high energy efficiency, low energy consumption, economy, safety and portability, dehydronaphthalene dehydrogenation is still the best choice for fuel cell hydrogen source.
