Porous ball, also known as filtering ceramic ball, is formed after
boring on the basis of inert alumina ball or ceramic column. Both
porous ball and inert alumina ball share the same accumulation voidage, and play the role of catalyst coverage & support and vapor-liquid
separation. Comparing with the perforated ball, there're more pores in
the porous ball body. Comparing with inert alumina ball, structured
pores with absorption function increased by 20-30% so that it can filter
impurities in the oil.
As oil impurities are in the form of
granular, pectic, bitumen-like and heavy metals, part of them can be
filtered out after going through raw material filter. But there is still
a significant portion, e.g. those granular impurities or iron ion which
size less than 25μm, is not able to filter out. If porous ball is loaded
on the top of the reactor, those impurities, which was not removed
from raw material early, will be filtered out after absorption of porous
ball. Therefore, catalyst will be protected to ensure unit operation and
equipment run smoothly.
Based on content and granular size of impurities inside raw material, relevant
porous ball with specific aperture and certain number of pores will be
applied to meet customer's requirements. If necessary, active agent,
e.g. molybdenum, nickel, and cobalt, can be loaded to prevent the
catalyst from carbon-coking and poisoning.
For Liaohe
Petrochemical Company, our porous ball has been applied in her hydrogenation
& refining plant of 600,000MT coking gas & diesel oil, which
performance is highly appreciated and the separation of the impurities
can reach over 75%.
