Titanium-modified activated alumina has the following significant advantages compared with unmodified activated alumina:
Optimized surface properties
After introducing titanium, the acidity and alkalinity, adsorption performance, etc. of the material surface are regulated, which can better meet the requirements of specific reactions for catalyst carriers, such as enhancing the adsorption capacity of reactants and improving the selectivity of catalytic reactions.
01
Enhanced thermal stability
The addition of titanium can inhibit the crystal form transformation and sintering of activated alumina at high temperatures, enabling it to maintain a stable pore structure and large specific surface area in high-temperature reaction environments (such as hydrogenation processes in petrochemicals), thereby extending its service life.
02
Enhanced catalytic synergistic effect
Titanium and alumina may form a synergistic effect, not only serving as an excellent carrier to load active components but also interacting with them to enhance the overall activity of the catalyst, especially in reactions such as hydrodesulfurization and denitrification.
03
Better pore structure control
Through titanium modification process, the pore size distribution of the material can be made more uniform, and the pore volume and specific surface area can better meet the actual application requirements, which is conducive to the diffusion of reactants and products in the pore channels and improves the reaction efficiency.
04
Expanded application scope
With the above performance advantages, Titanium modified activated alumina application scenarios are more extensive. It is not only suitable for the traditional petrochemical field but also can play a better role in environmental protection waste gas treatment, fine chemicals and other fields, with stronger adaptability.

Caution: Because of activated alumina ball has strong water absorption so do not open the package before use to avoid moisture absorption and affect the use effect.
Titanium Modified Activated Alumina Main Application
In the petrochemical field: As a catalyst carrier for reactions such as hydrorefining and hydrocracking, it can effectively enhance the catalyst's ability to remove sulfur and nitrogen-containing compounds, as well as its conversion performance for heavy oil, adapting to the trend of heavy and inferior crude oil.
In the field of environmental protection: Titanium modified activated alumina is used for waste gas treatment, such as the adsorption and catalytic conversion of harmful gases like nitrogen oxides and sulfur dioxide, which can enhance adsorption efficiency and catalytic activity, and reduce pollutant emissions.
In other fields such as fine chemicals and pharmaceuticals, Titanium modified activated alumina can also be used as a catalyst carrier or adsorption material for specific chemical reactions and separation processes, which helps to improve product quality and production efficiency.
