GB/T 47051-2026 Takes Effect: A Renewal Window for Spent Activated Carbon Regeneration Equipment
China's first systematic national standard for thermal regeneration of spent activated carbon, GB/T 47051-2026, took effect on 1 August 2026. It sets mandatory requirements for temperature control, enclosed negative-pressure operation, energy limits, regenerated carbon quality and emission control — putting many existing regeneration kilns under compliance pressure. This article reviews the key requirements, compares mainstream kiln types and outlines three response paths.
Refractory Selection and Maintenance for Activation Furnaces: Key to Extending Furnace Life and Reducing Energy Consumption
Refractory materials are the core of stable operation and energy control in activation furnaces. This article provides practical recommendations on working-layer refractory selection, masonry quality, drying and maintenance cycles, and common damage repair to help activated carbon plants extend furnace life and reduce refractory costs per ton.
