Mercury Mitigation Sorbent

United Conveyor Corporation has partnered with Carbonxt to offer oxidizing Powdered Activated Carbons (PACs) for the removal of mercury in emissions control applications.

Our combined expertise in PACs and Activated Carbon Injection (ACI) equipment and/or ash handling system operation, provides a holistic solution that simplifies our Customers’ efforts to comply with emissions control regulations.

Carbonxt offers customized PACs that are engineered with the flexibility to meet unique plant requirements in the most economical manner. Their innovative technology and manufacturing processes are extremely versatile, allowing each PAC product to be customized specifically around the plants unique needs. Each of Carbonxt’s CXT™ PAC product families can be enhanced with a proprietary additive and/or an extremely low percentage of bromine for enhanced oxidation and optimal sorbent performance.

CXT PAC Benefits

• Alleviates corrosion to the ductwork and equipment

Lower injection rates

Injection tailored to meet plant needs

State-of-the-Art Laboratory

Continuous advancements and solutions for compliance

Product Family



Cxt-1000 is well suited for plants operating near their compliance limit or with high levels of oxidized Hg.


Cxt-2000 products have an improved pore structure for applications with lower sulfur and/or lower oxidized Hg content.


Cxt-3000 products have optimized pore structures for challenging Hg removal applications such as: high elemental Hg, high sulfur coal and/or Hg content, or low residence time in the duct.

Carbonxt PACs have been proven to perform better than or equal to other leading mercury sorbents in head-to-head tests. In many cases, they outperform brominated PACs with the use of little to no bromine or other halogen. The CXT family of products can be optimized for the specific application to minimize injection rates and costs for the end user. In most cases, this includes the addition of Carbonxt’s proprietary, non-corrosive additive to aid in mercury oxidation. Testing is encouraged to quantify results and economics, as well as to help optimize the product for the application.
  1. Does Carbonxt’s additive include bromine?[+]

    No. The proprietary additive does not include bromine or any other halogen. In specific scenarios, a small amount of bromine can be added to the PAC with the proprietary additive to achieve required mercury oxidation while minimizing corrosion potential.

  2. How can Carbonxt cost-effectively produce custom material?[+]
    Carbonxt’s manufacturing method eliminates the large plant designed to make a one-size-fits-all “optimized” product. Instead, Carbonxt uses commercially available base PACs and upgrades them in regional facilities. This allows for more flexibility, reliability, and lower cost to the end user.
Activated Carbon Injection

M-PACT™ /m-pact_modular_system.aspx The M-PACT is a compact, modular unit designed by Albemarle to provide cost-effective PAC (powder activation carbon) utilization.   Its stand-alone design is equipped with on-board PAC storage that incorporates both the metering and conveyance operations of ACI into
