Catalytic reaction support material

Rhenium plates can serve as catalyst carriers or components, utilizing their high melting point (3180 ℃) and corrosion resistance to maintain catalytic activity in reactions such as hydrocracking and reforming. Its surface structure has optimized the dispersion of precious metal catalysts such as platinum, resulting in a 20% -30% increase in crude oil conversion efficiency.

Core components of high-temperature reactor

In the hydrogenation refining process at 480-530 ℃, the reactor liner made of rhenium plate exhibits excellent resistance to hydrogen sulfide corrosion, and the equipment life is extended by more than three times compared to traditional nickel based alloys. Its anti sintering properties can operate continuously for over 8000 hours without failure.

Key materials for process optimization

The catalyst system supported by rhenium plate reduces the catalytic cracking reaction pressure from 4MPa to 2.5MPa, while increasing the diesel yield to 42% (about 35% in traditional processes). This technology has been applied in 65% of advanced refineries worldwide.

Special environmental structural components

In the deep desulfurization device, the distributor made of rhenium plate can maintain structural integrity in media with sulfur content greater than 3%, and its thermal shock resistance can reach 300 cold and hot cycles without cracking, far exceeding ordinary alloy materials.
