Quarterly Technical Report
Summary of Technical Progress
Tests were conducted in the Transport Reactor Test Unit (TRTU) to study
gasification and combustion of Rose Bottoms using the spent FCC (Fluid Catalytic Cracker)
catalyst as the circulating medium at temperature of 1690*F. The Rose (Residuum Oil
Supercritical Extraction) Bottoms was produced in the Kellogg's Rose unit. Studies were
done in the Bench Scale Reactor Unit (BRU) to characterize petroleum coke with respect
to pyrolysis and agglomeration tendency upon heating to 1800*F. Studies were conducted
in the CFS (Cold Flow Simulator) to determine the various aeration flowrates required for
satisfactory circulation of petroleum coke in the TRTU. Results from these studies are
presented in this report. A dry solid feed system was developed and tested for use in the
In the second quarter, the work plan called for accomplishing the following work as
part of tasks 31 and 32: Task 31 - TRTU tests were to have been carried out on
processing ROSE Bottoms (ROSE Bottoms was prepared in Kellogg's ROSE pilot plant
facility). Task 32 - Cold flow simulator (CFS) testing on petroleum coke and testing of a
coke feeder was planned. Actual accomplishments are described below.
The planned work hours for this period were 3178 hr. The actual work hours were
Task 31: The pyrolysis and gasification of ROSE Bottoms, prepared from Hondo crude oil,
were performed in the 3rd quarter. Low temperature partial oxidation (LTPOX) tests on a
blend of Rose Bottoms and light cycle oil (LCO) using FCC catalyst and K-impregnated
FCC catalyst was conducted. Gasification of this carbon utilized potassium carbonate
(K2C03) as the catalyst. -The BRU was used to study agglomeration tendencies of
petroleum coke upon heating to 18000F. Petroleum coke runs in the TRTU are now
planned for the 4th quarter of 1996.
Task 32:- -Studies were done in the CFS to investigate the circulation of petroleum coke
and to determine the aeration flows required to operate the TRTU with these solids. A solid
feeder consisting of a vertical screw was designed, fabricated and tested successfully on
Results of TRTU test using Rose Bottoms blend and operating in a nonadiabatic
gasification mode are discussed below.
