Full Automation

The BSD-660 series offers complete automation throughout the entire testing process, including self-checks, free zone measurements, material activation, and in situ adsorption testing. It eliminates the need for manual handling of sample cells, heating furnaces, or Dewar cups, allowing researchers to focus on higher-level analysis rather than repetitive tasks. Once material activation is complete, the system automatically manages the entire workflow—performing in situ degassing, adjusting the heating furnace, and switching between Dewar cups with LN2 or a water bath as required. With its high-throughput capabilities and fully automated operation, the BSD-660 enhances lab efficiency, precision, and functionality, delivering a seamless, hands-free testing experience.

Pressure Control Heating

The Pressure-Controlled Heating (PCH) function intelligently adjusts the heating rate based on real-time pressure signals, ensuring a stable and controlled outgassing process. This precision control protects the integrity of pore structures, preventing damage during testing. Additionally, the PCH function minimizes the risk of material powders being displaced and carried into the pipeline or manifold, preserving both the sample and the system's functionality. This feature ensures optimal performance and reliability throughout the testing process.

Synthesis of Defect-Rich Titanium Terephthalate with the Assistance of Acetic Acid for Room-Temperature Oxidative Desulfurization of Fuel Oil Gan Ye, Yulong Gu, Wei Zhou, Wei Xu, Yinyong Sun

The development of highly active oxidative desulfurization (ODS) catalysts is of practical importance for producing clean fuel oil. Recently, metal–organic frameworks (MOFs) have been attempted as ODS catalysts. However, the studies found that most of the MOFs were less active in ODS reactions mainly due to the lack of defect sites in the structure. Therefore, the synthesis of MOFs with defect sites has been pursued. Herein, porous titanium terephthalate with rich defect sites can be prepared with the assistance of acetic acid by the solvothermal method. The obtained material exhibited not only extraordinary ODS activity for the removal of DBT (87.1 mmol h–1 g–1) in model oil at room temperature but also simultaneously the strong ability of separating the sulfone product from the oil phase with a total sulfur removal content of 117 mg S/g catalyst when the concentration of 500 ppmw S in model oil was used. Such good catalytic performance could be mainly attributed to the creation of rich defect sites, high surface area, and the exposure of abundant active sites in the structure of the porous titanium terephthalate.
