Starting in the late 1980s, it gradually entered the industrialization phase and found extensive applications in various fields.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">The advantages of asphalt-based spherical activated carbon are notable. It boasts high strength, low impurity content, excellent sphericity, smooth surface, impressive adsorption performance, access to abundant raw materials, and affordability.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">However, there are some drawbacks to consider. The preparation process and equipment required for asphalt-based spherical activated carbon are complex. In practical production, the commonly used gas phase oxidation treatment is time-consuming, energy-intensive, and results in low output. Alternatively, the use of liquid phase oxidation treatment necessitates thorough cleaning of the obtained asphalt balls, generating a substantial amount of waste liquid that can potentially cause severe pollution. These limitations pose challenges to the production of asphalt-based spherical activated carbon.<\/span><\/p>\n<h3 style=\"line-height: 1.75;\"><span style=\"font-size: 12pt;\"><strong><span style=\"color: #181818;\">1.2 Coal-based spherical activated carbon<\/span><\/strong><\/span><\/h3>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">The coal-based spherical activated carbon developed in the late 1970s has a relatively mature process and is mostly used in the biochemical field. The production process adopts the disk rolling ball making method, and the manufacturing equipment and process are relatively simple.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">Coal-based spherical activated carbon is characterized by its low cost, but it does have certain drawbacks. These include a relatively high ash content, poor strength, low sphericity, and subpar adsorption performance. The production of high-quality coal-based spherical activated carbon necessitates stringent requirements for the raw coal, such as low ash content, high activity, and potentially other specific criteria.<\/span><\/p>\n<h3 style=\"line-height: 1.75;\"><span style=\"font-size: 12pt;\"><strong><span style=\"color: #181818;\">1.3 Polymer-based spherical activated carbon<\/span><\/strong><\/span><\/h3>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">The preparation of spherical activated carbon with synthetic polymer materials can avoid various disadvantages of asphalt-based and coal-based spherical carbon. At present, there are two main types of synthetic polymer based spherical activated carbon: one is phenolic resin based spherical activated carbon, the other is ion resin based spherical activated carbon. These polymeric materials have high carbon content and low ash content, with better compressive strength compared with other raw materials.<\/span><\/p>\n<ul style=\"line-height: 1.75;\">\n<li><span style=\"color: #181818;\">Phenolic resin-based spherical activated carbon<\/span><\/li>\n<\/ul>\n<p style=\"padding-left: 40px; line-height: 1.75;\"><span style=\"color: #181818;\">Curing agent and pore forming additive are added in the preparation process of phenolic resin-based spherical activated carbon, so it has the advantages of simple process, low cost and easy control of pore size distribution.<\/span><\/p>\n<ul style=\"line-height: 1.75;\">\n<li><span style=\"color: #2dc26b;\"><strong><a style=\"color: #2dc26b;\" href=\"https:\/\/www.allcarbon.com.cn\/ion-resin-based-activated-carbon\" target=\"_blank\" rel=\"noopener\" data-page_id=\"0\" data-page_name=\"\" data-page_type=\"\"><span style=\"text-decoration: underline;\">Ionic resin-based spherical activated carbon<\/span><\/a><\/strong><\/span><\/li>\n<\/ul>\n<p style=\"padding-left: 40px; line-height: 1.75;\"><span style=\"color: #181818;\">In the early 1980s, spherical activated carbon can be made with ion resin as the precursor through carbonization and activation processes.<\/span><\/p>\n<p style=\"padding-left: 40px; line-height: 1.75;\"><span style=\"color: #181818;\">Since the 1990s, scientists have proposed to use different polymer materials for synthesis, and then without melting and carbonization treatment can get spherical activated carbon.

Alternatively, the use of liquid phase oxidation treatment necessitates thorough cleaning of the obtained asphalt balls, generating a substantial amount of waste liquid that can potentially cause severe pollution. These limitations pose challenges to the production of asphalt-based spherical activated carbon.</span></p>
<h3 style="line-height: 1.75;"><span style="font-size: 12pt;"><strong><span style="color: #181818;">1.2 Coal-based spherical activated carbon</span></strong></span></h3>
<p style="line-height: 1.75;"><span style="color: #181818;">The coal-based spherical activated carbon developed in the late 1970s has a relatively mature process and is mostly used in the biochemical field. The production process adopts the disk rolling ball making method, and the manufacturing equipment and process are relatively simple.</span></p>
<p style="line-height: 1.75;"><span style="color: #181818;">Coal-based spherical activated carbon is characterized by its low cost, but it does have certain drawbacks. These include a relatively high ash content, poor strength, low sphericity, and subpar adsorption performance. The production of high-quality coal-based spherical activated carbon necessitates stringent requirements for the raw coal, such as low ash content, high activity, and potentially other specific criteria.</span></p>
<h3 style="line-height: 1.75;"><span style="font-size: 12pt;"><strong><span style="color: #181818;">1.3 Polymer-based spherical activated carbon</span></strong></span></h3>
<p style="line-height: 1.75;"><span style="color: #181818;">The preparation of spherical activated carbon with synthetic polymer materials can avoid various disadvantages of asphalt-based and coal-based spherical carbon. At present, there are two main types of synthetic polymer based spherical activated carbon: one is phenolic resin based spherical activated carbon, the other is ion resin based spherical activated carbon. These polymeric materials have high carbon content and low ash content, with better compressive strength compared with other raw materials.</span></p>

</ul>
<p style="padding-left: 40px; line-height: 1.75;"><span style="color: #181818;">Curing agent and pore forming additive are added in the preparation process of phenolic resin-based spherical activated carbon, so it has the advantages of simple process, low cost and easy control of pore size distribution.</span></p>

</ul>
<p style="padding-left: 40px; line-height: 1.75;"><span style="color: #181818;">In the early 1980s, spherical activated carbon can be made with ion resin as the precursor through carbonization and activation processes.</span></p>
<p style="padding-left: 40px; line-height: 1.75;"><span style="color: #181818;">Since the 1990s, scientists have proposed to use different polymer materials for synthesis, and then without melting and carbonization treatment can get spherical activated carbon. This synthetic spherical activated carbon has the characteristics of high strength, no impurities and high catalytic activity.</span></p>
