BASF provides products, technologies and expertise to support all stages of flue gas carbon capture workflow. Their F-200 spherical activated alumina dry desiccant is an exceptional dry desiccant with superior crushing strength, resistance to amines and low abrasion rates.
Alumina’s physical structure plays an integral part in mass transport and catalyst performance, with surface area, pore volume, pore size distribution and shape all having an effect.
Activated Alumina
Activated alumina is a highly porous form of aluminium oxide with an extensive network of interconnected pores that creates exceptional moisture-absorption capabilities. This makes activated alumina popularly used in applications involving liquid and gas drying, air purification and catalytic reactions.
Activated alumina desiccants offer more advantages over silica gel desiccants in terms of moisture absorption after being exposed to heat, making it the go-to choice for industrial liquid and gas drying applications where temperature fluctuation occurs frequently. Hơn nữa, activated alumina desiccants are less costly compared to other industrial desiccants like silica gel or molecular sieves.
One key benefit of this adsorbent is its resistance to chemical and physical shocks, including sudden temperature shifts or mechanical stress without breaking down, providing long-term reliability.
Water treatment with activated carbon is widely utilized to remove harmful contaminants such as fluoride and arsenic from drinking water sources, while natural gas and petrochemical processing also utilizes activated carbon to dehydrate natural gases to meet strict quality standards for liquefaction and transportation purposes.
Users handling activated alumina must take precautions to avoid breathing in its dust particles. A dust mask may help minimize dust exposure while making sure there is adequate ventilation. Hơn nữa, materials should be stored in tightly sealed containers so as to prevent contamination or premature absorption by unwanted molecules.
Catalyst Support Materials
Proper selection of catalyst supports or carriers is a critical element in ensuring successful industrial chemical processes. By giving main catalysts the freedom to interact with reactants efficiently and selectively, selecting appropriate carriers allows these processes to work at peak performance.
BASF’s extensive range of catalyst support materials is tailored to provide reliable catalyst performance and productivity across a variety of applications, from alumina and silica through carbon to alumino-silica gels and more. All are carefully balanced between physical and chemical parameters to achieve reliable catalyst performance and high productivity across numerous reactions and process conditions.
Alumina is widely recognized for its thermal stability and often employed as a carrier material in heterogeneous catalysis reactions that require high temperatures, like hydrocarbon cracking and disproportionation. Silica offers higher surface area with minimal pressure drop, making it an excellent candidate for dehydration of alcohols to olefins as well as excellent acid-base properties; bifunctional versions may even incorporate metal oxides.
Carbon-based supports are used for numerous reactions, such as photocatalysis and fuel cells. Selecting an effective carbon support is key in optimizing these electrochemical reactions – essential to power generation – such as photocatalysis and fuel cells. Choosing an alumina support with narrow microporosity for Co/TiO2 catalyst has shown higher CO conversion rate than silica support with wider pores.
Microfine Alumina
Micro-alumina polishing powder can be used for either manual or machine polishing, usually in conjunction with lubricants to evenly disperse and scatter its particles. It has hard, wear-resistant particles with very fine particle sizes for high filling capability that achieves smooth finishes even on rough surfaces, filler/extended in polishing compounds, fillers for epoxy adhesives or extender in polishing compounds and filler and extenders in polishing compounds. Haixu’s white fused alumina (Al2O3) which has been heated at over 1000degC to expel volatile impurities found in crude metal oxide samples such as soda found there – giving it good purity, high grinding ability and excellent distribution capabilities compared to crude metal oxide samples from raw metal oxide samples found elsewhere on abrasives used elsewhere on abrasives used elsewhere on surface finishes aluminas.
Glass and ceramic polishing: Micro alumina powder can help eliminate scratches, water spots, haze, or any other defects found on surfaces and materials such as glass. It can also be used to polish ceramic items such as tiles and pottery or composite materials such as composite plastics.
Due to its high surface area and thermal stability, silicon carbide makes an ideal catalyst support material for chemical reactions involving organic molecules. Hơn nữa, its insulation properties enable its use as an ingredient for manufacturing refractory materials like furnace and kiln linings; additionally it plays an integral role in producing advanced industrial ceramics.
Molecular Sieve Adsorbents
Molecular Sieve is an exceptional crystalline material with precise and uniform pores that allow it to selectively adsorb specific molecules based on size. Due to this property, molecular sieve has become an indispensable element of many gas separation, purification and dehydration processes.
A molecular sieve is composed of crystals engineered into cage-like structures by engineers that feature channels with interconnecting channels and “sieve holes”. When synthesized, the size of these pores can be meticulously controlled during production; this creates a “sieve” which permits certain molecules to pass through while screening out larger ones. Based on application needs, different molecular sieve adsorbents are available with pores between 3-10 Angstroms for use as molecular sieve adsorbents can also vary in their performance.
Molecular sieve desiccants are non-hazardous and cost-effective solutions, boasting superior mechanical strength and durability due to their crystalline structure. As such, they are often chosen for gas separation applications as their unique ability to withstand heat, pressure, dirt and other stresses is unparalleled.
Molecular sieve adsorbents are stored in cylindrical beds which the stream to be treated passes through, like an open sewer. Each bed can either be used once before being discarded or be regenerated multiple times over an extended timeframe; its capacity decreases with increased regeneration cycles, so it’s crucial that an appropriate “end-of-run” capacity be built into your design plan.
