Fundamental reaction pathways during coprocessing
Deuterium incorporation into Lloydminster resid and asphaltene was accomplished via acid and base-catalyzed hydrogen-deuterium exchange reactions. More specifically, the acid-catalyzed exchanged reaction was carried out with trifluoromethanesulfonic acid-d (triflic acid-d). The acid-catalyzed deuteration of Lloydminster resid was measured by {sup 2}H NMR spectroscopy and the results are presented in Table 1. The base-catalyzed exchange reaction was carried out with Lochmann's Base. As shown in Figure III and Table III, Lochmann's Base Catalyzes the H-D exchange of a wide variety of protons, principally benzylic, substituted benzylic and highly-branched alkyl protons. Lloydminster asphaltene was successfully methylated with the use of tetrabutylammonium hydroxide as base and carbon-13-labeled methyl iodide as alkylating agent. {sup 13}C NMR spectroscopy indicate that the resid was methylated at oxygen.
