摘　　要：液化天然气汽车(LNGV)用于城市小轿车时,因夜间停驶或较长时间停运时,储罐内LNG的蒸发可能迫使燃料储存系统安全阀开启放气,增加小型LNGV的安全环境风险。结合LNGV燃料储存系统的主要特点,开展了低温低压下甲烷在高表面炭质吸附剂(SYJ-2)上的吸附性能研究。结果表明,在温度238～161K,压力1.5MPa下,吸附剂对甲烷的吸附量为0.16～0.3g/g,即82～153mL/mL。吸附天然气(ANG)可望用于LNGV燃料储存系统,以增加LNGV燃料储存系统的安全性。When liquefied natural gas vehicles （LNGV） is used for city cars, due to the lay-off at night or a long time outage, evaporation of LNG in the tank could force the safety valve of the fuel storage system opening so as to release natural gas, which increases security environment risk of LNGV. Combined with the main characteristic of LNGV fuel storage system, methane adsorption performance on high surface area carbon adsorbent （SYJ-2） was researched under the low temperature and low pressure. The results showed that methane adsorption capacity by the adsorbent is 0.16-0.3 g/g, namely 82- 153 ml/ml, on the condition of 238- 161K and 1. 5 MPa. Adsorbed natural gas （ANG） could be used for LNGV fuel storage system so as to improve its safety.
