Sulphur-detecting indicators for determining life time of adsorbents, sulfur-removal canister and system composed of the same

摘要

desulfurization adsorbent of the present invention is judged for life discoloration indicating device, which includes a desulfurization vessel and desulfurization system in about that, more specifically, showing a gas containing organic sulfur compounds (Natural gas) or liquefied petroleum gas (LPG) and the organic sulfur compounds from fossil fuels discoloration such as effectively to judge the life of the desulfurization sorbent capable of removing adsorbed indicating device is related to the desulfurization vessel and desulfurization system including the same. According to ; The present invention uses a desulfurization sorbent can simply remove organic sulfur compounds give a replacement point of the adsorbent can be determined by visual or electrical signals, such as the city is required seuna liquefied petroleum gas desulfurization easy to process applications are possible, in particular, is especially useful for the hydrogen generator for a fuel cell system for simplified or unmanned operation is required for home fuel cell system of the device or distributed generation.
