In this experimental study firstly a sulphur-bearing alkanethiol-derivatised gold nanoparticles has been selected and prepared. The alkanethiol-derivatised gold was put in the mud-stone samples bearing terreau. In varies elevated temperature the gas products were collected by foam plastics in a special installation. The measurements on the contents of gold in foam plastics and on the composition of gas phase were carried out and the comparisons for various samples were made.

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℃).
