Kushiyama et al (129) reported that phosphorus also promotes the activity of highly divided unsupported molybdenum and cobalt-molybdenum sulfide catalysts for HDS (and HDM) of crude oil, with a maximum at a P/(Co + Mo) atomic ratio of 2. This result warrants attention because it shows that phosphorus may directly modify the active sulfide phase(s) even in the absence of the alumina support. 

In some cases gas with a high sulfur content coming from partial oxidation or gasification units is passed directly to shift conversion. The high sulfur content can be tolerated by magnetic type catalysts, although the activity is reduced [221]. But more efficient sulfur tolerant catalysts based on cobalt-molybdenum sulfide have become available [169, 242-245]. With such catalysts...
