A binary catalyst system for upgrading an RTI ID = 0.0 evoluted / RTI bed to produce an improved quality vacuum residue product

摘要

Applied bed hydrogenation treatment systems are upgraded using a two-way catalyst system that includes heterogeneous catalysts and dispersed metal sulfide particles to improve the quality of the vacuum residue. Improved quality vacuum residues can be provided by one or more of reduced viscosity, reduced density (increased API specific gravity), reduced asphaltene content, reduced residual carbon content, reduced sulfur content, and reduced precipitate . Improved quality vacuum residue can be generated while operating the upgraded applied bed reactor at the same or higher severity, temperature, throughput and / or conversion rate. Similarly, the same or higher quality vacuum residue may be generated while operating the upgraded applied bed reactor at higher severity, temperature, throughput and / or conversion rate.
