Hydrotreating naphthas

Hydrocracking of the mid-distillate and gas oil to produce naphtha and LPGs (3) hydrotreating of the straight run naphtha and hydro-crackate naphtha to remove heteroatoms and (4) reforming of the hydrotreated naphthas to maximize aromatics. [Pg.149]

Reforming. The hydrotreated naphthas were reformed over a conventional platinum reforming catalyst in an attempt to maximize aromatics. The catalyst was Cyanamid AERO PHF-4 (0.3% Pt, 0.6% Cl). The intent was to operate the reformer at constant conditions in order to better compare naphthas. By operating at severe conditions, the expected hydrocracking activity of the catalyst would tend to purify the aromatics by selectively cracking away the paraffins. If the resultant reformate had a suitably high aromatic content, it could be fed directly to a hydrodealkylator. [Pg.158]

Hydrotreated naphthas (combined) were then reformed over a 0.6% Pt on A1203 catalyst at 500°C, 500 psig, 3 LHSV, and 5 M scf H2/bbl. This simple catalyst was chosen in preference to the more advanced bi- and trimetallic catalysts because of its probably lower sensitivity to heteroatom poisoning. The reformates were analyzed by gas chromatography... [Pg.106]

The mercaptans in the feedstock, which was about 56 percent of the total sulfur, was reduced to about six percent at 220°C and then increased to about 36 percent at 300°C and to about 57 percent at 350°C as shown in Table 4. These data confirm the occurrence of mercaptan forming reaction along with HDS of other types of sulfur. Similar results were observed by Sekhar and Rahimi while hydrotreating naphtha derived from coal liquids and heavy oil [12]. Our data show that the maximum temperature of operation for catalyst/4 is 300°C, above which recombination reactions become dominant. [Pg.231]

Verderone et al. studied the influence of chloride content on the activity, selectivity, and stability of a commercial Pt(0.3)-Re(0.3)/AI2O2 catalyst using as feed a typical hydrotreated naphtha at conimercial conditions. Also for comparison purposes chlorided aluminas were used. The chloride concentration of the commercial catalyst was adjusted from 0.15% to 1.15% Cl and the results were... [Pg.86]
