Abstract
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.
