Rate enhancement for catalytic upgrading coal naphthas
During this quarter, hydrotreatment of the Black Thunder naphtha sample was carried out using two commercial catalysts. Also, the Illinois No. 6 naphtha were hydrotreated using unsupported transition metal sulfides. Each reaction condition was maintained for 24 hours and three steady state samples were taken in the last 6 hours of the 24 hours period to calculate the removal of the heteroatoms for each condition. Prior to G.C. analysis, the samples were washed three times with distilled water to remove dissolved H[sub 2]S and NH[sub 3]. Two commercial catalysts, a Co-Mo on alumina (American Cyanamid HDS-1442A, 1/16in. [times] 1/4in. pellets) and a Ni-W on alumina (Harshaw Catalyst, Ni-4301, E 1/12, Lot 16, Drum 29) were employed in the processing of the Black Thunder naphtha samples. Analytical data for these catalysts are presented in Table 1. Unsupported transition metal sulfides were prepared following the procedure published by Chianelli et al.
