摘　　要：通过对国际上车船加注用液化天然气产品的讨论,结合我国液化天然气生产销售和产品标准等现状,探讨我国制定车船加注用液化天然气产品质量的要求。车船加注用液化天然气应与国内现有液化天然气产品质量指标一致并体现车船加注液化天然气的特点。在甲烷、丁烷以上组分,二氧化碳、氮气和氧气这些组分摩尔分数方面,应与GB/T 38753—2020《液化天然气》一致。考虑环保和燃烧特性,可适当提高硫化氢和总硫含量要求,硫化氢含量宜不超过3.5 mg/m^(3),总硫含量宜不超过5.0 mg/m^(3)。Based on the discussion of LNG products for vehicles and ships in the world,combined with the current situation of China’s LNG production and sales and product standards,this paper discusses the China’s quality requirements of LNG products for vehicles and ships.The quality indexes of the LNG products for vehicles and ships shall be consistent with the quality indexes of existing domestic LNG products,and reflect the characteristics of the LNG for vehicles and ships.The mole fraction of methane,butane plus,carbon dioxide,nitrogen and oxygen shall be consistent with the provisions of liquefied natural gas(GB/T 38753-2020).Considering the environmental protection and combustion characteristics,the requirements for hydrogen sulfide and total sulfur content can be appropriately improved.The hydrogen sulfide content should not exceed 3.5 mg/m^(3) and the total sulfur content should not exceed 5.0 mg/m^(3).
