Abstract (en)

[origin: EP0518269A2] In the process of producing high calorie SNG type city gas from hydrocarbonic crude gas, e.g., butane, propane, naphtha etc., an elementary feed gas is produced by using hydrodesulfurization as a first step, and then secondly further methanizing the product in a column. The hydrodesulfurization uses a nimox catalyst and a zinc oxide adsorbent. The desulfurized feed gas is further methanized on an alumina group carrier supported by nickel to obtain methane-rich gas, i.e. the elementary feed gas in a combined use type column. The necessary hydrogen to be fed into the hydrodesulfurization is obtained from a methanol/water mixture. This hydrogenizing reaction tube is combined within the same column above. Inorganic salt is used as a heat transfer medium heat-sourced in an external furnace and the heat transfer medium temperature branched into two system-flows are controlled by a three-way flow rate control valve simultaneously. The above reaction temperature is about 320<o>C.
