What is the difference between the suspended-bed hydrogenation developed by Sanyu and conventional hydrocracking?

What is the difference between the new suspended-bed hydrogenation process developed by Sanju Environmental Protection and the existing suspended-bed hydrogenation processes as well as the existing coal tar hydrogenation projects? I hope the experts here can give me some advice
From what I understood before, the catalyst is added to the oil; it’s in liquid form. The oil, along with hydrogen, enters the reactor, which should be similar to the coking tower used in coking processes, but at a much higher pressure. CNPC conducted research on this, but did not proceed with large-scale implementation. I’m surprised that local refineries managed to succeed with this approach, but I’m still a bit skeptical – there might still be a significant amount of coke produced, and more tail oil would need to be discarded when the raw materials are of poor quality.
