Development and Industrial Application of Alumina Dry Adhesive Powder

With the acceleration of the world’s industrialization process and the continuous improvement of people’s quality of life, the contradiction between petroleum consumption and supply has become increasingly prominent. The quality of alumina dry rubber powder required for petroleum catalysts such as cracking catalysts, reforming catalysts and hydrogenation catalysts directly affects petroleum processing. s efficiency. Therefore, the development of alumina dry rubber powder for hydrogenation catalysts has become a key research topic for universities and research institutes. Hydrogenation catalyst activity is one of the key technical indicators, and catalyst activity is closely related to the performance of alumina dry rubber powder. The alumina dry rubber powder used for the catalyst should have the characteristics of large pore volume, high specific surface area, uniform pore size distribution, and suitable surface acidity and alkalinity.

China's dependence on alumina import market is expected to increase

According to foreign media news on April 20, Morgan Stanley analyst JoelCrane stated in a report that China's recent announcement of electricity price subsidies for the industrial sector is the main reason for the rise in spot alumina prices. Morgan Stanley said that the Australian spot export price has risen to US$342.25 per ton, after hitting a six-month low of US$334 per ton. The investment bank said that China's domestic stock of bauxite is 30 million tons. China's dependence on alumina import market is expected to increase

China's alumina imports fill the supply gap

According to foreign news on February 25, an analyst at Metal Bulletin Research said on Wednesday that China’s alumina market had insufficient supply last year, but imports filled the supply gap. At the 21st Bauxite and Alumina Conference hosted by Metal Herald, analyst Yang Cao said that China’s alumina supply and demand gap was 3.84 million tons last year, but the import volume was about 5.28 million tons. This resulted in 1.44 million tons of alumina stored in warehouses throughout the year, he added. The increase in alumina imports is partly due to concerns that Indonesian ore export restrictions may affect the supply of bauxite ore, which is the raw material for alumina. He said that in 2014 there was a surplus of 50 million tons of smelted grade alumina, and the annual aluminum output reached 27.5 million tons. The largest alumina production area is Shandong Province, followed by Shanxi and Henan Provinces. Affected by restrictions, alumina imports have also become diversified. Yang said that before 2014, China mainly imported from Australia. Currently, imports from Brazil, India and Vietnam are increasing. "We expect Australia to remain China's largest bauxite exporter, and Malaysia may follow closely behind and become China's second largest bauxite exporter." "China will also start from India, Fiji, Brazil, Ghana, Dominican Republic, Imported from Guinea and Guyana, but Chinese bauxite importers still face many issues to consider-such as quality, infrastructure constraints and transportation costs," he said at the meeting.

Alumina carrier catalyst, preparation and use

Alumina supported catalysts are used in many conversion reactions of hydrocarbons. They can be used in fixed bed reactors, moving bed reactors or circulating fluidized bed reactors. In all the use of these reaction beds, the attrition of the catalyst is important. During the packing of a fixed catalyst bed, the fragmentation of the catalyst may be quite obvious, while in a moving bed or circulating fluidized bed reactor, the catalyst must be attrition resistant. The shape of the catalyst particles can vary, but in order to obtain a uniformly packed catalyst bed, the catalyst particles are preferably spherical. A convenient method for preparing spherical alumina catalysts is the oil drop method, in which droplets of alumina hydrosol and gelling agent are passed through a hot oil bath. The method of preparing spherical alumina with high density and high crushing strength from alumina hydrate by the oil drop method is disclosed in the U.S. Patent (Patent No. 4,542,113) and the claims filed in the patent. The method includes the use of specific characteristics Alumina sol, and then urea is mixed into the sol. In addition to a high degree of wear resistance of the catalyst, for some specific applications, it is desirable for the catalyst to have a low packing density. The low packing density of the catalyst must mean that the catalyst has more pore structure, which generally leads to an increase in the activity of the catalyst.
