Microporous ceramic ball is also known as filter ceramic ball, inert ceramic ball internal structure microporous 20-30% adsorption. The role of the different types of microporous Ciqiu different the the produced microporous Ciqiu MH-1, MH-2, MH-3 Three types of microporous Ciqiu.
Microporous ceramic ball is therefore in addition to the role of the catalyst and the dispersed vapor-liquid has the same inert ceramic ball support coverage, while adsorption filter impurities in the oil. The oil impurities form granular, mucilaginous, Lek Qing and heavy metals and other impurities in raw filter can filter out part, but there is still a considerable part (for example, less than 25μM particulate impurities and iron ions) or can not be filtered out. Filling MH porous ceramic ball as in the top of the reactor can not filter out the impurities in the raw materials adsorption in its hole, thereby protecting the catalyst, and the extension of the operating cycle of the apparatus.
Depending on the type of the impurities in the raw materials processed in the hydrogenation, hydrogen production and reformer device, the content and the particle size is different, the user can choose a different pore size and pore number of porous ceramic ball, also based on the activity of need annexed molybdenum, nickel, cobalt, etc. the parts to prevent the coking of the catalyst coking and poisoning.
