氧化鋁板常被用作加氫處理催化劑的載體,由于渣油分子量較大,直鏈較多,很難進出一般氧化鋁板的孔道內,然后導致渣油的加氫處理功率不抱負。
Alumina plate is often used as the carrier of hydrotreating catalyst. Because of the large molecular weight of residual oil and the large straight chain, it is difficult to enter and exit the pore of general alumina plate, and then the hydrotreating power of residual oil is not ambitious.
現在工業上首要通過沉積、枯燥和焙燒氫氧化鋁板前驅體來制備氧化鋁板載體,其孔道通透性低,孔徑偏小且散布較寬,難以滿足日趨變重的重質油的加氫處理過程。
Nowadays, alumina plate carriers are mainly prepared by deposition, drying and calcination of alumina plate precursors. The pore permeability of alumina plate carriers is low, the pore size is small and the distribution is wide, so it is difficult to meet the increasing heavy oil hydrotreating process.
因此制備出具有高比外表積、高度有序結構、大孔徑、外表酸性中心等杰出特點的氧化鋁板資料,顯得尤為重要。 氧化鋁板有12種以上,現在首要運用的有α-A12O3、β-A12O3和γ-A12O3這3種晶型。其間γ-A12O3只在低
Therefore, it is particularly important to prepare alumina sheet materials with high specific surface area, highly ordered structure, large pore size and external acidic center. There are more than 12 kinds of alumina sheets, and the three crystal forms, alpha-A12O3, beta-A12O3 and gamma-A12O3, are mainly used now. In the meantime, gamma-A12O3 was only low

Alumina plate carriers are mainly prepared by deposition, dryness and calcination of alumina plate precursors in industry. The pore permeability is low, the pore size is small and the distribution is wide. It is difficult to meet the hydrotreating process of heavy oil which is getting heavier and heavier. Therefore, alumina plate data with high specific surface area, highly ordered structure, large pore size and external acidic center are prepared. It seems particularly important.
氧化鋁板有12種以上,現在首要運用的有α-A12O3、β-A12O3和γ-A12O3這3種晶型。其間γ-A12O3只在低溫下安穩存在,高溫下會變得不安穩,不會溶解于水,但會溶于酸、堿。
There are more than 12 kinds of alumina sheets, and the three crystal forms, alpha-A12O3, beta-A12O3 and gamma-A12O3, are mainly used now. In the meantime, gamma-A12O3 only exists stably at low temperature, and becomes unstable at high temperature. It will not dissolve in water, but will dissolve in acid and alkali.


因其有較大的比外表 α-A12O3是在較高溫度下能夠安穩存在的相態,其熔點為2050℃,不溶于水,亦不溶于酸和堿,耐腐蝕,化學性質安穩,常見以剛玉為代表。其他相態暫認為是過渡態或不安穩態,研討較少。
Because of its larger specific appearance, alpha-A12O3 is a stable phase at a higher temperature, its melting point is 2050 C, insoluble in water, acid and alkali, corrosion resistance, chemical stability, commonly represented by corundum. Other phase states are temporarily considered to be transitional or unstable, and few studies have been carried out.
氧化鋁板開展至今,已出現許多可行性工藝,根據其應用不同而有針對性地加工處理,可得到特定需求的滿足產品。
Since the development of alumina sheet, there have been many feasible processes. According to their different applications, processing can be targeted to meet the specific needs of products.
對其描摹的研討亦多元化,幾乎一切的組成中,都在尋找一種令組成產品優越、操作簡略且能耗較低的方法。依照氧化鋁板生長平面空間方向的不同可分為一維棒狀、片層狀及球曲面狀。
Discussions on its description are also diversified. Almost all of the components are looking for a way to make the products superior, simple operation and the lowest energy consumption. According to the spatial orientation of the growth plane of alumina plate, it can be divided into one-dimensional rod, lamellar and spherical shape.
