Calcined Diatomite CAS 91053-39-3 for Catalyst Support in Chemical Industry
Calcined Diatomite CAS 91053‑39‑3 is porous inorganic carrier produced by high‑temperature calcination of natural diatomite ore. It possesses developed pore channels, proper specific surface area and outstanding chemical inertness. This material is widely applied as catalyst support in chemical industry, helping load active catalytic components, disperse active sites, improve catalyst thermal stability and service life, fit for petrochemical, fine chemical and chemical synthesis processes.
Overview
Our calcined diatomite CAS 91053‑39‑3 is manufactured through high‑temperature calcination, purification and particle‑size classification. Stable pore structure is retained after thermal treatment. With controllable pore volume, good acid‑resistant performance and high thermal stability, this grade is specially developed as catalyst support for chemical industry. It avoids structural collapse under reaction conditions, optimizes mass transfer efficiency of reactant molecules, improves overall catalytic reaction efficiency.
Key Features
- Developed interconnected pore structure, suitable specific surface area for loading catalytic active ingredients.
- Excellent thermal stability, keep stable physical structure under high‑temperature chemical reaction environment.
- Good chemical inertness, resist erosion by most weak acid and organic reaction media.
- Adjustable particle size and pore distribution to match different catalyst preparation requirements.
- High mechanical strength, reduce powdering and crushing during catalyst forming and industrial operation.
- Inorganic mineral substrate, low impurity content, minimize side reactions in chemical processes.
Main Applications
- Catalyst support for petrochemical hydrogenation, dehydrogenation reactions
- Carrier for fine chemical synthesis catalysts
- Support for organic synthesis and catalytic reforming catalyst
- Adsorption‑catalysis integrated reaction system
- Chemical industry fixed‑bed reactor catalyst carrier
Usage Recommendation
- Select suitable particle size and pore specification according to reaction system and catalyst preparation craft.
- Conduct pre‑treatment such as washing and calcination before loading active metal or chemical components.
- Match forming process including extrusion, tabletting or spray granulation for finished catalyst production.
- Strictly control raw material moisture to prevent pore structure change during high‑temperature pretreatment.
Storage & Package
- Store in dry and ventilated warehouse, keep bags tightly sealed against moisture absorption.
- Standard package: 25kg woven bag with inner PE liner.
