SRC-I naphtha hydrotreating study pilot plant and oxygen analytical studies. Final technical report
The first part of this study covered second-stage pilot plant hydrotreating using a UOP nickel-molybdenum (-moly) catalyst and first-stage product from earlier pilot plant work as feedstock. Results from this study indicate that the nickel-moly catalyst is less active than the cobalt-moly catalyst used during original studies over the lower end of the temperature range tested (250 to 280/sup 0/C average bed temperature (ABT)), but should produce satisfactory product contaminant levels at the temperature range of commercial interest (335 to 345/sup 0/C ABT). The second part of the study covered oxygen analysis comprising two separate programs. The first was aimed at determining the effect of various molecular sieve drying techniques on SRC-I hydrotreated naphtha. This resulted in the recommendation that 3A molecular sieves be left in contact with the naphtha before analysis to assure that the sample remains relatively dry (approx. 20 wt-ppM water), and therefore minimize water interference during analysis. The second program was conducted to determine if different oxygen concentrations in the range of 10 to 100 wt-ppM. The results showed that scatter in the analytical data was too large to permit conclusions relative to the type of oxygen compound. Further combustion/GC analytical method development is recommended. In general, the results from the oxygen analytical study are very beneficial to the ongoing effort to develop an accurate method for total oxygen analysis in the 10 to 100 wt-ppM range. 3 figures, 12 tables.
