The HT environmental protection protecting agent is our company newest development the patent product (patent number ZL*******5.8).This product is increases the cover supporting catalyst protecting agent take the high pure aluminum oxide as the main raw material which the special ingredient purification becomes. In the structure in the circumference slot circle opened the hole to achieve both guarantees certain compressive strength and to increase its ratio surface area and the percentage of voids. As a result of this product *0~*0% percentage of voids, the multitudinous pores and open the hole to be possible to filter in the oil quality granulated, impurities and so on sol shape, asphaltene, heavy metal. These impurities after process raw material filter although may filter out a part, but still had is smaller than quite partially *5 μm following pellet impurities and the hard ion is unable to filter out. Loads this protecting agent in the reactor crown to be possible raw material in the filtration impurity adsorption in its, thus achieved the protection catalyst does not coke, also guaranteed the installment operation cycle lengthens goal.
The impurity type and the content different as well as the pellet size is different in processing raw material, the user selects the different aperture and the different Kong Shu environmental protection protecting agent. Also may according to the need, active constituents and so on appendix molybdenum, nickel, cobalt, prevents the catalyst sinks carbon coking and the poison. In the petroleum chemical industry, rallies, installment uses and so on the hydrogenation, system hydrogen, burnt carburetion, diesel oil hydrogenation purification should guarantee protects the medicinal preparation result to indicate that, it can filter the impurity effectively; And can protect the catalyst period of revolution effectively, the extension installment on-stream period, increased the oil quality circulation area, can cause the system pressure drop to 0.1Mpa below, made the equipment process load to enhance *6.5%, had the catalyzed diesel oil to mix in the ratio to be possible to reach *7%~*0% circulation area.
