Description

Data on the HDN-30 and the Ketjenfine-124 catalysts not previously reported are given. These data show pore properties and reveal that the Ketjenfine catalyst has a most frequent pore diameter at about 50 angstroms and that of the HDN-30 catalyst at about 80 angstroms. A comparative figure revealed that no difference existed in nitrogen removal for over 120 hours of catalyst-oil contact for these two catalysts and for a reactor bed consisting of a 50 volume percent mixture of each. The Catalyst Life Test Unit was modified to improve the feed control. Two high pressure feed tanks were installed which ... continued below

Description

Data on the HDN-30 and the Ketjenfine-124 catalysts not previously reported are given. These data show pore properties and reveal that the Ketjenfine catalyst has a most frequent pore diameter at about 50 angstroms and that of the HDN-30 catalyst at about 80 angstroms. A comparative figure revealed that no difference existed in nitrogen removal for over 120 hours of catalyst-oil contact for these two catalysts and for a reactor bed consisting of a 50 volume percent mixture of each. The Catalyst Life Test Unit was modified to improve the feed control. Two high pressure feed tanks were installed which allow improved feed-pump performance while operating with preheated, heavy feedstocks. Analytical methods were developed for the scanning electron microscope and atomic absorption to assess more detailed analysis of catalysts properties and metals content of the oils. One experimental run was conducted using the HDN-30(Ni-Mo-Al/sub 2/O/sub 3/) catalyst and a feedstock consisting of 10% (vol) Synthoil II and 90% Raw Anthracene Oil. This experiment was conducted at nominal conditions of 1500 psig, 427 C and with a liquid volume hourly space time of 2.74 hours. The run duration was 103 hours of liquid-catalyst contact. Only partial results were available; all will be given in the subsequent quarterly report. Sulfur removal was noted to be 75 to 83%.
