Abstract: The cermet free of residual pores is prepared by putting a fuse- precipitating body on carbide skeleton body heating and fuse- precipitating at 1350-1450 deg.C under the vacuum condition. The skeleton body is consists of 60-70% TiC-10-20% Mo2C-5% Ni or 60% TiC-20% Mo2C-5% (Ni-Co) and is presintered at 1100-1300 deg.C under the vacuum condition. The fuse-precipitating body consists of Ni, Ni-7% TiC-8% Mo2C, Ni-10-20% Co or Ni-10-15% Fe. The produced cermet has a compsn. of 70% TiC-10% Mo2C-20% Ni, 60% TiC-20% Mo2C-20% (Ni-Co) or 60% TiC-20% Mo2C-20% (Ni-Co-Fe).

Abstract: A method for recovering methane gas by adding a mixed gas of nitrogen and carbon dioxide to natural gas hydrate, thereby reacting the mixed gas with the natural gas hydrate is provided. A method for recovering methane gas from natural gas hydrate comprises the step of adding a mixed gas of nitrogen and carbon dioxide to natural gas hydrate to substitute the mixed gas for the methane gas. The mixed gas is prepared by mixing nitrogen with carbon dioxide at a mole ratio of 1:9 to 9:1. The method comprises adding the mixed gas to the natural gas hydrate until it reaches to 30 to 200 atmospheric pressures while maintaining a temperature of 0 to 5 deg.C, and reacting the mixed gas with the natural gas hydrate for 9 to 20 hours. A method for recovering methane gas from natural gas hydrate comprises the step of adding flue gas containing nitrogen and carbon dioxide to the natural gas hydrate until it reaches to 30 to 200 atmospheric pressures while maintaining a temperature of 0 to 5 deg.C to substitute the mixed gas for methane gas for 9 to 20 hours.
Abstract translation: 提供了一种通过向天然气水合物中加入氮气和二氧化碳的混合气体来回收甲烷气体，从而使混合气体与天然气水合物反应的方法。 一种从天然气水合物中回收甲烷气体的方法，包括向天然气水合物中加入氮气和二氧化碳的混合气体以将混合气体替代为甲烷气体的步骤。 混合气体通过将氮与二氧化碳以1：9至9：1的摩尔比混合来制备。 该方法包括向天然气水合物中加入混合气体，直至达到30至200个大气压，同时保持0至5℃的温度，并使该混合气体与天然气水合物反应9至20小时。 从天然气水合物中回收甲烷气体的方法包括将含有氮气和二氧化碳的废气加入到天然气水合物中直至达到30至200个大气压并同时保持温度为0至5℃以替代 甲烷气混合气9至20小时。
