Demetallization Catalyst Tests on Heavy Residual Oils.

摘要

The report gives results of a cooperative project between the U.S. and the USSR to exchange technology on the demetallization step of an overall process to produce low sulfur fuel oil from heavy petroleum residua. Catalysts and petroleum residua feedstocks were exchanged and tests were carried out by each nation using its own equipment and operating procedures. Test results were exchanged and discussed at meetings in both the USSR and the U.S. In this report,all tests using U.S. catalysts were described by the U.S. and all tests using USSR catalysts were described by the USSR. Each nation described its own test equipment and operating procedures. Included for each aging test are graphs showing the degree of demetallization and desulfurization and the rate of catalyst deactivation. Fresh and used catalyst analyses are presented,along with detailed run summaries and product inspections. Each nation's molybdenum-impregnated catalyst exhibited about equal demetallization capability;however,the U.S. catalyst exhibited higher desulfurization capability during demetallization. Sections of this report collaborated on and reported jointly include the summary,introduction,and conclusions. The project was considered mutually beneficial.
