Attempts to rationalize the distribution of hydrocracked products. I qualitative description of the primary hydrocracking modes of long chain paraffins in open zeolites
TL;DR: In this article, the authors explore the hydroisomerization-hydrocracking network and show that all cracked products with carbon numbers from C4 to C8 are generated by a combined action of four β-scission mechanisms.

Shape-selectivity changes in high-silica zeolites
TL;DR: In this paper, peak indexation and microscopic examination were used to identify the phases and to examine the samples for degree of crystallinity, measured by temperature-programmed desorption of NH3 and infrared examination of OH groups upon interaction with hydrogen-bond-acceptor molecules.

Attempts to rationalize the distribution of hydrocracked products. II. Relative rates of primary hydrocracking modes of long chain paraffins in open zeolites
TL;DR: In this paper, a combination of energetically distinct routes for carbenium ion ion rearrangement and cracking was used to predict the individual composition of the cracked products, from this, the relative rates of the reaction routes have been determined.
