Abstract

The aim of this work is to develop a catalyst for the hydroisomerization of a straight-run hydrotreated diesel fraction to allow the production of a diesel fuel with improved cold flow characteristics. Some catalyst samples containing zirconia modified with tungstate anions, high-silica zeolite, noble (Pt, Pd) or transition (Ni, Mo) metals, a binder (alumina), and promotors are synthesized. The samples are subjected to laboratory tests at temperatures of 250–360°C, a pressure of 3.0 MPa, feed hourly space velocities (FHSVs) of 1.5–3.0 h–1, and an H2/feedstock ratio of 1000 m3/m3. The target product yield relative to feedstock on GITs-1 (with Ni, Mo) and GITs-2 (with Pt, Pd) is 84.6 and 91.0 wt %, respectively, and the depression of the cloud and cold filter plugging points in comparison to the feedstock was 20°C for both catalysts. The possibility of producing a diesel fuel for a cold climate in compliance with GOST R (Russian State Standard) 52368–2005 or a winter diesel fuel in compliance with TR TS (Customs Union Technical Regulation) 013/2011 is shown.
