Abstract: A device for measuring the amount of desorbed gas has a sample desorption tank; a water drain metering assembly that has a metering tube configured to display a liquid level height and receive gas desorbed from the sample desorption tank, the metering tube being connected to a draining and injecting assembly for draining or injecting water, a first pressure monitoring member for monitoring a liquid pressure in the metering tube, and a second pressure monitoring member for monitoring a gas pressure in the metering tube; a gas exhausting assembly that is in communication with the water drain metering assembly and configured to exhaust desorbed gas therein; and a control assembly for controlling the desorbed gas to enter the metering tube, controlling the draining and injecting assembly to drain water, controlling the gas exhausting assembly to exhaust gas, and controlling the draining and injecting assembly to inject water.

Abstract: A device and method for simulating dynamics of hydrocarbon generation and expulsion in geological process is provided. The device contains a reaction system which has a reactor having a sample chamber formed therein for placing a sample and a sample sleeve being arranged within the sample chamber for receiving the sample. The sample sleeve has a cylindrical body enclosing the sample in a circumferential direction, an outer side wall of the cylindrical body being in engagement with an inner side wall of the reactor, and the cylindrical body being perforated to form a channel for product circulation between an outer side wall of the sample and the inner side wall of the reactor.
