ABSTRACT:

The first run of the pilot plant, CT-256-1, was successfully concluded after sixty-one days on stream. In this experiment, the evaluation of the first Fischer-Tropsch catalyst, a Fe/Cu/K sub 2 CO sub 3 catalyst designated as I-A, was carried out. Furthermore, a second-stage ZSM-5 catalyst, designated as II-A, was on stream for forty-nine days. The operation went very smoothly and was highly successful considering the complexity of the pilot plant. The second-stage catalyst readily converted the Fischer-Tropsch products (particularly the light olefins and heavy hydrocarbons) into high quality gasoline. A break-in regeneration of the second-stage Catalyst II-A was also successfully carried out. After the first run, several minor modifications were implemented to improve pilot plant operation, including installation of a new slurry loading pot to facilitate the catalyst loading and electric heating tapes at the three unheated flanges of the slurry reactor. Many automatic controls were also installed. These modifications significantly improved pilot plant operation. The second pilot plant run, CT-256-2, initiated and run for six days has demonstrated high catalyst loading, high gas throughput, and high synthesis gas conversion. It will continue into the next reporting period.  Evaluation of the raw gasoline product from the two-stage operation has been initiated. Specifically, a modified Mobile corrosion test was conducted on two raw gasoline samples from run CT-256-1. Both samples showed trace-to-light corrosion similar to a reference unleaded gasoline.  (ERA citation 08:017490)
