Zhongchuang has focused on the production and sales of activated carbon for decades. We are familiar with the application and common sense of activated carbon.
Once coal-based granular activated carbon reaches adsorption saturation, its purification efficiency declines significantly. Therefore, it requires periodic replacement. Typically, a replacement cycle of 3 to 6 months is common.
From household water purification to municipal water supply, and from industrial ultrapure water production to the upgrading of various wastewater treatment systems, coconut shell activated carbon has emerged as the material of choice for water treatment, thanks to its superior adsorption capacity, higher structural strength, and excellent chemical stability.
For oxygen production, lithium molecular sieves (such as LiX type) or high-performance modified zeolite molecular sieves (such as 13X, 5A type) should be preferred. This type of molecular sieve has a higher nitrogen and oxygen separation coefficient and adsorption capacity. It can efficiently separate oxygen in the air and produce oxygen-rich gas with a purity of 90%-95%. It is suitable for medical, health care and industrial scenarios.
Activated carbon can effectively remove residual chlorine, odor, organic pollutants and some heavy metals in drinking water treatment, significantly improving water quality and taste. Its core function comes from its developed microporous structure and huge specific surface area (up to more than 1000m²/g), which can adsorb a variety of harmful substances and is widely used in household water purifiers and municipal water plants for deep purification.
Activated carbon mainly absorbs organic pollutants, pigments, odors, formaldehyde and other harmful gases, as well as some heavy metal ions. Its strong adsorption capacity comes from its highly developed porous structure and huge specific surface area (up to 500–1700m²/g), which can capture a variety of impurities through physical adsorption and chemical adsorption.
The process by which activated carbon adsorbs mercury relies primarily on its high specific surface area, well-developed pore structure, and surface chemical modification. The specific mechanisms can be broadly categorized into two modes: physical adsorption and chemical adsorption—with sulfur-loading modification significantly enhancing adsorption efficiency.
Choosing a desulfurization product depends on your specific application scenario and the type of sulfide being treated. Different industries, different types and concentrations of sulfides require significantly different desulfurization products and technologies.
Unlike zinc oxide desulfurizers, which are mainly used in medium-temperature, fine desulfurization applications, iron oxide desulfurizers offer unique and significant cost and operational advantages in their respective fields.
Zinc oxide desulfurizer is a highly efficient solid adsorbent used to remove hydrogen sulfide (H₂S) from industrial feed gases. It is renowned for its core advantages: deep desulfurization, high sulfur capacity, and irreversible reaction.
In the oxygen production field, zeolite molecular sieve is currently the most widely used core technology, especially in applications requiring oxygen concentrations above 90%. However, the specific molecular sieve selection depends on a comprehensive consideration of your application, oxygen purity, energy consumption, and budget.
In pressure swing adsorption (PSA) systems, activated carbon, thanks to its excellent pore structure and surface properties, serves as one of the core adsorbents for the selective adsorption of carbon dioxide (CO₂). Its application principle revolves around the core PSA mechanism of "pressure-driven adsorption, pressure reduction-driven desorption." Through precise control of process parameters and adsorbent performance, efficient CO₂ separation and recovery is achieved. The following detailed analysis of its application logic encompasses four dimensions: technical principles, key steps, activated carbon property requirements, and process design.
Aperture Matching Principle: Effective adsorption requires the activated carbon's pore size to be an order of magnitude larger (approximately 10 times) than the target pollutant molecule. Dioxin molecules are approximately 1.8 x 1.0 x 0.4 nm, so the optimal pore size for adsorption is concentrated in the mesopore range of 2-5 nm.
