Bench-scale co-processing, Technical progress report No. 21, July 1, 1993--September 30, 1993

PDF Version Also Available for Download.

Description

Objective is to establish a database for optimizing the co-processing concept by improving the effectiveness of the co-processing catalyst system. Two major mechanisms for improving the catalyst system are to be investigated: more effective catalysts (subtask 3.2.1) and improved catalytic environments (3.2.2). During this period, work on 3.2.2 was carried out and the bench-scale co-processing pilot plant was operated in the counter-current mode. The counter-current process in presence and absence of a packing material under different operating conditions was evaluated. Project objective of achieving 90+% conversion of the 510 C nondistillate at 2000 psig was not met due to plant ... continued below

The counter-current process in presence and absence of a packing material under different operating conditions was evaluated. Project objective of achieving 90+% conversion of the 510 C nondistillate at 2000 psig was not met due to plant limitations. Because of reactor size and throughput, flow regime within the reactor is laminar. It is believed that without turbulent flow, there was insufficient mixing to keep the catalyst in solution; it probably attaches to the reactor walls, forming a restriction which causes all material entering the reactor to immediately exit through the reactor outlet. No additional counter- current co-processing experiments are planned, and the pilot plant will be reconfigured to operate in the co-current mode.
