Decalin catalytic cracking

In the case of bicyclic naphthenes most of the work in catalytic cracking was done using decalin (Bloch and Thomas, 15 and Greensfelder... 

We attempted to compare our results to earlier reports for catalytically active Si-VPI-5 samples, however, relevant results for a direct comparizon were not found. Martens et al. [6] and Kraushaar-Czametzki etal. [13] reported their results for Pt/Si-VPI-5 bifunctional catalysts in the isomerisation of n-decane [6], and in the hydroconversion of n-heptane, respectively. Davis et al. also used metals supported on VPI-5 to test catalytic reactions [12]. Our main interest were the cracking capability and the selectivity to useful fuel fractions, using the Si-VPI-5 catalysts in reactions of trans-decalin (model compound) or atmospheric residue. 

Ryoo and co-workers synthesized MFI zeoHtes with varied morphology by means of a surfactant as structure-directing agent [76]. The zeolitic catalysts so fabricated were found to exhibit superior catalytic activities during decalin cracking reactions. To correlate the observed reactivity with acid properties of the catalysts, the P-R3PO NMR approaches with TMPO and TBPO probe molecules were exploited. The P NMR spectra of TMPO and TBPO adsorbed on various MFI zeohtes are compared to a...
