The study shows that the activation energy of most shell is 1/3-2/3 of the limestone, the product-layer coefficient magnitude is 1 magnitude higher than that of limestone, and the specific surface area, specific pore volume, and the average pore radius are all bigger than that of limestone. So shells are fit for coal combustion sulfur retention in high temperature (900-1000℃).

Partition coefficients of neutral aromatic solutes in LEKC between 288~323 K were measured. A series of thermodynamic parameters were obtained by third-order polynomial fitting Van't Hoff plots. The thermodynamic partitioning behavior of those solutes was investigated. The results showed that the partition coefficient became greater with the increment of temperature and the number of CH2 functional groups on benzenering.
