Model compounds hydropyrolysis

Conventional thermal cracking of pure hydrocarbons has been studied extensively in the past, and well-substantiated mechanistic proposals have been outlined (7-19). In contrast, hydropyrolysis of pure model compounds has been studied to a lesser extent and has been confined mostly to low (Ci-C5) paraffins, and simple alkylbenzenes and naphthenoaro-... 

A further difference between HP products and coker distillate is noted in the olefins content. Infrared spectral data taken neat on these twj products reveal olefin bonds at 1638, 988, 960, 904, and 880 cm about 1.5 to 2.0 times as intense for coker distillate compared to HP condensables. Based on analysis of gases produced and on model compound work (5) which both show hydropyrolysis inhibits olefin production, it is anticipated that hydropyrolysis products will be more stable for storage, transportation, or distillation than coker distillates from the same source.
