The catalytic performance of a hydrocracking bifunctional catalyst and consequently its activity loss depend on the balance between metal (M) acid (A) functions. Commonly, function is reputed to stabilize should therefore alleviate deactivation. In order test this hypothesis, study aimed assess impact oxide (MoO3) content deactivation vacuum gasoil (nickel-molybdenum sulfide dispersed carrier c...

Cr5Mo steel with high thermal strength is frequently applied as the material for hydrocracking furnace tubes. Nonetheless, tubes are prone to failure in a high-temperature environment, threatening production safety. Considering that IN718 nickel-base superalloy has favorable oxidation resistance, coating was fabricated on substrate through laser cladding. The effect of process parameters resist...

The Urals and Siberian vacuum residues are considered difficult to process in the ebullated bed hydrocracking because of their increased tendency form sediments. Their achievable conversion rate reported literature is 60%. Intercriteria analysis was used assess data from a commercial residue hydrocracker during processing blends three residues: Urals, Light, Basra Heavy. revealed that main cont...
