摘要:
This invention relates to supported multi-metallic catalysts for use in the hydroprocessing of hydrocarbon feeds, as well as a method for preparing such catalysts. The catalysts are prepared from a catalyst precursor comprised of at least one Group VIII metal and a Group VI metal and an organic agent selected from the group consisting of amino alcohols and amino acids. The catalyst precursor is thermally treated to partially decompose the organic agent, then sulfided.

In various example embodiments, a system and method for displaying an update to a geographical area are presented. An indication of an update to geographical area is received. The geographical area is displayed on one or more devices. Moreover, the geographical area includes an artifact that corresponds to geospatial data. The update to the geographical area is generated based on the received indication of the update. Data that causes display of the generated update to the geographical area is transmitted to each of the one or more devices.

This invention relates to a process for activating a hydroprocessing catalyst and the use of activated catalyst for hydroprocessing. More particularly, hydroprocessing catalysts are activated in the presence of carbon monoxide. The catalysts that have been activated by CO treatment have improved activity.
