A light diesel fuel was produced by distillate hydrotreating of the straight-run Fe-HTFT material, while the heavier fraction was hydrocracked over a dewaxing catalyst, which produced a heavy diesel (Table 18.10). Some diesel fuel was also produced by C3-C4 olefin oligomerization over solid phosphoric acid by recycling the naphtha thus produced. It has previously been pointed out that solid phosphoric acid is not well suited for distillate production,42 and the hydrogenated...

In the case of distillate hydrotreating the simulation models are simply described even for the complicated reaction scheme employed in the reaction model as discussed in the later section, because the catalyst deactivation is not necessarily predicted for local sites in the system. And the assumption confirmed in the previous discussion that the relationship between the Thiele-modulus and effectiveness factor is approximately represented by that of a first order reaction for any reaction order makes the simulation model simpler and easier to develop. 

An example in Figure 7 presents the gas-liquid mixed phase activation for the presulfided catalyst (60 t) in a 120,000 BPSD Distillate Hydrotreating unit. The activation reactions started at 140 °C with exotherm of delta T of 39 °C at the maximum, which subsided within...

A breakthrough distillate hydrotreating catalyst, jointly developed by ExxonMobil and AkzoNobel, was recently commercialized and deployed in three refineries. This catalyst has three to ten times the activity of the most active current HDS/HDN catalysts, depending on pressure. This catalyst also exhibits novel and unique pressure sensitivity from 400 psi Hydrogen-2 pressure up to 2,000 psi Hydrogen-2. It represents a major advance in catalyst performance, composition, structure, and morphology. The product is stripped not only of sulfur but also nitrogen and achieves substantial aromatic saturation. 

Ever more stringent regulations on sulfur contents in gasoil, from 50 ppm in 2005, down to below 10 ppm in 2009, requires a twofold increase in the catalytic performances of distillates hydrotreating catalysts. This gives rise to new and tough challenges in a field where a lot a research has been done in the last thirty years.
