Basic Info of Decahydronaphthalene

What is Decahydronaphthalene?

Decahydronaphthalene, likewise called decalin, is a natural compound that liquifies rubber, materials, waxes, fats and also oils. It is a colorless aromatic hydrocarbon, which can be used as a substitute for turpentine, cleaning fluid and also detergent. Decalin has also been made use of in the past as a varnish remover for oily paint.

Decalin is a harmful, high-boiling, colorless natural liquid with a mild menthol smell. It is a common polycyclic alkane component in gasoline. It is generally utilized as a solvent and also paint remover for grease, resin, rubber, etc. Representatives such as decalin as a solvent can utilize its distributing impact to improve asphaltene hydroconversion. However, in the thermal breaking procedure of decalin under different temperature level and also stress problems, the hydrogen transfer response is prone to create aromatic hydrocarbons, which will certainly lower the conversion rate in the petroleum catalytic splitting procedure, and also lower the yield and value of high value-added items such as fuel as well as diesel. As a result, how to pick an ideal stimulant to control the breaking of decalin as well as explore its fracturing regulation has come to be a research study hotspot. Furthermore, in regards to hydrogen storage products, decalin has a great development prospect and also is usually used as a hydrogen storage space product for fuel cells.

Decahydronaphthalene Uses

  1. Solvent of naphthalene, wax, fat, oil, resin and rubber; Engine fuel and lubricating oil; Clean the machinery; Replace turpentine; Shoe cream; Detergent.
  2. Decahydronaphthalene is used as a liquid for refractive index measurement and also as a solvent.
  3. Decahydronaphthalene can be used as the solvent of paint to extract fat and wax, and instead of turpentine, it can be used in the manufacture of shoe polish and floor wax. Decahydronaphthalene can be mixed with benzene and ethanol as the fuel of internal combustion engine.

Application of Decahydronaphthalene

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.
