This research produced heterogeneous catalyst of 纬-Al2O3 in single phase, nanoparticle size and the atomic weight ratio of Al/O = 2/3 (0.6667) by method which is easier and more economically. The commercial catalyst activity is limited by the formation of coke and pores of the catalyst [...
8, there are three characteristics of the solution: (1) uniformity; (2) stability; (3) mixture. Three in 9, chemical formula: (1) said in response to what material, what the result of material; (2) said, the number of particles of reactant molecules or atoms produced each sub...
Chemical fouling involves autoxidation, polymerization, cracking or coke formation which can enhance its complexity. In bulk flow thermal instabilities of chemical species such as protein can form precursors which consequently results in deposits on heat transfer surface. Like other types of fouling ...
1.It can also be prepared by the reaction of alumina and carbon tetrachloride at room temperature (Al2O3 + 3CCl4 = 2AlCl3 + 3COCl2) 2. Aluminum oxide powder method: put the industrial alumina with a certain particle size and petroleum coke into the roasting furnace in a certain proportion...
