AI Technical Summary
Due to carbon residue, large specific surface area, and small pore volume, MTO spent catalysts are difficult to bond with silicate cement, resulting in poor overall performance of the prepared blocks. Furthermore, traditional treatment methods pose environmental pollution and energy consumption problems.
A building block was prepared by combining a magnesium oxychloride gelling system with MTO waste catalyst, and by adding lightly calcined magnesium powder, magnesium chloride hexahydrate and modifiers to form a stable gelling system. The particle size distribution was improved by using fillers, and the block was cured at room temperature.
This method enables the resource utilization of spent MTO catalysts, reduces environmental pollution, improves the overall performance of building blocks, reduces energy consumption, meets building material standards, and the preparation process is environmentally friendly and efficient.
