1 Preparatory work before commencement； 2 Hydrogen pipeline system explosion ； 3 Nitrogen purging, airtightness (activate the hydrogen compressor to increase pressure if necessary) ； 4. Dry the furnace; incidentally, dry the reaction system as well ； 5. Load the catalyst. 6. Dry the catalyst and conduct another airtightness check (first with nitrogen, then with hydrogen). 7. Pre-sulfurize the catalyst ； 8 Switch the feed oil and adjust the operations
