On June 4, the fixed-bed residual oil hydrogenation catalyst (PHR series) independently developed by China Petrochemical Research Institute was successfully started up at the residue oil plant of Dalian Westpac Company, filling the gap
in PetroChina residual oil hydrogenation catalyst technology.
Residue oil hydrogenation is the most effective residue oil raw material conversion and treatment technology, catalyst is its core technology, but its high technical content, difficult research and development, application conditions are extremely harsh, is a difficult hard bone, the core technology is only a few international large companies mastered
.
PetroChina's existing residual oil hydroprocessing capacity is 15 million tons per year, and the annual import catalyst volume is about 5,000 tons, so it is urgent
to accelerate the research and development of catalyst technology with independent intellectual property rights.
After years of hard work, the Petrochemical Research Institute has successfully developed 6 new catalyst preparation technologies such as flexible regulation of pore structure and non-uniform distribution of active metals, overcome the problem of preparation of special macropore carriers suitable for the diffusion of residue macromolecules, and designed and developed 4 series of 12 grades of residue oil hydrogenation catalysts with gradient, bimodal peak, smoothness and concentrated pore integration characteristics, realizing the optimal gradation
of various catalyst functions 。 PHR series catalysts have undergone small-scale testing, pilot test, industrial scale-up, 6000 hours of long-cycle operation of pilot plant and 10,000 hours of hanging basket test of industrial device, and the results show that the performance index of the catalyst is comparable to the international advanced level, which fully meets the needs of the existing fixed-bed residue oil hydrogenation technology
