Heavy oil hydrocracking catalyst

Heavy oil hydrocracking catalyst. (Jushitsuyu Taisaku Gijutsu Kenkyu Kumiai, Japan). Jpn. Kokai Tokkyo Koho JP 58186444 A2 31 Oct 1983 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B01J035-02; B01J029-06; C10G047-12. APPLICATION: JP 82-69555 27 Apr 1982. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 67 The catalyst comprises a core of amorphous oxide and a shell of cryst. silicate, both loaded with Group VIII (Ni, Co) and Group VIB metals (Cr, Mo, W), to be active at high and low temp. (400-50° and 350-430°), resp., to produce H and low-boiling oil. Thus, 1/16-in. diam. 1314-35-8 and 1313-99-1 which are cas registry numbers are also used here. core of amorphous aluminosilicate loaded with Ni and W (contg. NiO 10, WO3 20, Al2O3 63, and SiO2 7%) was coated with zeolite slurry contg. Ni and W to 1/8-in. diam. (contg. NiO 10, WO3 20, Al2O3 30, and zeolite 40%). Kuwait atm. residual oil was hydrocracked at 100 kg/cm2 H, 400°, and space velocity 0.2 h-1. The conversion to oil b. ￡343° was ~70% with the fresh and ~40% with the used catalyst at a level of 0.33 lb/bbl oil. .

(VEB Leuna-Werke "Walter Ulbricht", Ger. Dem. Rep.). Ger. (East) DD 203744 A1 2 Nov 1983, 14 pp. (German). (German Democratic Republic). CODEN: GEXXA8. CLASS: IC: C10G045-38. APPLICATION: DD 82-237151 3 Feb 1982. PRIORITY: BG 81-51075 3 Mar 1981. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 67 Two-stage hydrotreating of a shale oil produced by low-temp. pyrolysis of oil shale (e. 1314-35-8 and 1313-27-5 which are cas registry numbers are also used here.g., in the presence of heat-transfer agents) consists of a initial hydrogenation at 613-623 K, 10-15 MPa, 2-3 h-1 (vol. space velocity), and 800-1 H-oil (vol.) ratio over sulfided 2.5-6.0:24.0-25 (or 15.5-25.0) (wt.%) NiO-WO3 (or MoO3) on g-Al2O3. This is followed by a 2nd-stage hydrogenation at 683-713 K, 14.6-15 MPa, 1-2 h-1 (vol. space velocity), and 1000-1 H-oil (vol.) ratio over the same catalyst or 3:24 NiO-WO3/aluminosilicate (contg. 20% SiO2) catalyst. The hydrotreating steps hydrogenate the olefinic double bonds, and reduce N and S contents by ~90% and 100%, resp. .
