PROBLEM TO BE SOLVED: To provide a system and method capable of stable desulfurization corresponding to a change in sulfur concentration with time from an LPG cylinder and capable of efficient desulfurization in LPG mainly by desulfurization by adsorption. SOLUTION: An LPG desulfurization system in which two or more desulfurization agents are installed in series in a gas flow path flowing from an LPG cylinder, and a room temperature desulfurization agent is arranged on the upstream side with respect to the gas flow direction. An LPG desulfurization system and a LPG desulfurization method, wherein a heated desulfurization agent is disposed on the downstream side. [Selection] Figure 1 |
