The role of the resid solvent in co-processing with finely divided catalysts. Quarterly report April--June 1993
The primary purpose of the work performed this quarter was to establish under thermal and catalytic reaction conditions whether hydrogen transfer occurred between cycloalkane type structures that are present in resids and heteroatomic species that are present in coal and liquefied coal. The research this quarter focused upon evaluating benzophenone (BENZ) as a model acceptor for hydrogen that might be transferred from a cycloalkane, perhydropyrene (PHP), under coprocessing conditions. Hence, a number of reactions was performed in which BENZ was reacted alone in hydrogen and nitrogen atmospheres in the presence and absence of a catalytic agent, molybdenum naphthenate. Reactions were also performed using a combination of PHP and BENZ at a 1 to 1 weight ratio. Also performing this quarter were initial separations with petroleum resids. Two different resids were used, Maya and LHC-362. The literature was also surveyed to determine important characteristics that should be evaluated for selecting resids. The resids that are desired for this project are resids with high-, medium-, and low-naphthenic content. Different levels of asphaltenes are also desirable. Resids with these characteristics are currently being sought. The model compound PHP that had been commercially available as naphthene representative of resids is now no longer available. Hence, several scoping experiments were performed in order to determine conditions for synthesizing PHP. The synthesis procedure reported in US Patent 3,303,227 was used as a basis for this work. Although more than 85% PHP was synthesized, partially hydrogenated pyrenes were also produced which will require separation in order to obtain pure PHP.
