Alfa Chemistry CatalystsInquiry Now
The main goal of the development stage is to determine the basic data required for industrialization: catalysts, reactor models, design standards, optimized process flow diagrams, etc. This phase is executed around the technical obstacles identified in the preliminary research conducted in the pre-development phase.
Alfa Chemistry Catalysts provides customers with catalyst process development services, including but not limited to the following types:
- Catalyst development
Preparation of catalyst oxide carrier and optimization of catalyst formulation and performance evaluation. The development phase also includes performance aspects (activity, selectivity, product quality) and process requirements (ensure a longer cycle, resistance to pollutants and deactivation, resistance to operation accidents).
- Molecular modeling and advanced characterization
Molecular modeling and advanced characterization techniques can play an important role in every step of catalyst development, including support synthesis and active phase composition optimization.

- Modern supported catalysts have many advantages, such as high surface area, small amounts of active metal components that are usually expensive, and high mechanical and thermal stability. The optimization of the manufacturing steps can reduce the batch-to-batch difference, and it is possible to reduce the metal load in the catalyst, thereby reducing the production cost. General industrial catalyst manufacturing involves multiple process steps, as shown in the figure below.

- Molecular modeling studies provide relevant insights for determining the reactivity of acid sites in the crystal network. For example, in the case of silica-alumina, the acidity modeling of amorphous surfaces has been carried out. Molecular modeling studies show that the pseudo-bridged silanol as a multifunctional Bronsted acid group is obtained by the transfer hydrolysis of Si-O-Al bridges.
