Catalytic slurry extraction technology

Thread Content

Extraction of catalytic slurry to produce rubber softeners and plastic plasticizers – anyone with experience in this area, please share your insights! The technical parameters are as follows: 1. The processing capacity of the oil slurry is designed to be 200,000 tons per year, and the products obtained are as follows: Product name, Yield, %; Output, 10,000 tons per year – Catalytic cracking wax oil: 35–40%, 7.0–8.0 tons per year; Rubber softening oil or plastic plasticizer: 40–45%, 8.0–9.0 tons per year; Asphalt modifier: 15–20%, 3.0–4.0 tons per year. 2. Product quality: (1) For the residue oil used as FCC feedstock, the key specifications are as follows: Analysis parameter, Specification – Density (20°C), kg/m3: ≯900; Kinematic viscosity (100°C), m²/s: ≯20; Flash point (open cup), °C: ≥180; Freezing point, °C: –30; Sulfur content, %: ≤0.5; Residue on ignition, %: ≤1.0. (2) Specifications for the extracted oil: Analysis parameter, Specification – Density (20°C), kg/m3: ≯1100; Kinematic viscosity (100°C), m²/s: ≯30; Flash point (open cup), °C: ≥180
