This invention introduces a method of preparing a carbon-based sulfur-loading iron-containing adsorbent for mercury removal, which can solve the problems in the prior art that sulfur-rich heavy organic materials have low-value utilization and the elemental mercury in atmosphere is hard to be efficiently and economically removed by the existing mercury removal agents. A carbon-based sulfur-loading iron-containing adsorbent for mercury removal is prepared in this invention. The adsorbent with a porous structure is prepared in situ by performing steps such as chemical activation of sulfur-rich heavy organic materials that are rich in iron. The adsorbent prepared herein has good mercury removal performance in simulated coal-fired flue gas. This invention not only improves the utilization value of sulfur-rich heavy organic materials, but also prevents SOpollution caused by the combustion of sulfur-rich heavy organic materials and controls mercury pollution in the coal-fired flue gas.

A device for determining an expansion pressure and an expansion displacement generated by coking coal based on self-regulation of a spring includes a pyrolysis reactor, which is provided in a high temperature carbonization furnace. Two porous pressing plates are provided at both sides of a coal sample, and two metal filter plates are provided at both sides of the sample. Upper and lower openings of the reactor are sealed respectively with a connecting flange. The pressing plate above the sample is connected to a mounting baffle of a detection mechanism through a lightweight connecting rod and a spring. The detection mechanism is provided with a displacement sensor and a pressure sensor. This application further provides a detection method using the above device.
