For recovering hydrogen with a high recovery from a reformed gas and contributing to downsizing and cost reduction of facilities, a high-purity hydrogen E is obtained by reforming a reformable raw material A through a reforming unitto yield a hydrogen-rich reformed gas B, compressing the hydrogen-rich reformed gas B with a compressor, allowing the compressed gas to pass through a PSA unitto remove unnecessary gases other than carbon monoxide by adsorption, and allowing the resulting gas to pass through a carbon monoxide removerpacked with a carbon monoxide adsorbent supporting a copper halide to remove carbon monoxide by adsorption.

Method of producing high-purity hydrogen

A process for producing silicon carbide whiskers by heating a react solid silicon-containing starting material and carbon-containing starting material in a reaction vessel, wherein a molding material, which is prepared by previously molding the silicon-cotaining starting material into a predetermined shape, and a powdery carbon starting material are heated to a predetermined reaction temperature under a hydrogen gas atmosphere. Silicon carbide whiskers which are linear with no bendings, long fiber length, high aspect ratio and low silicon dioxide impurity can be obtained at a high yield of greater than 90% based on silicon vaporized from the silicon-containing starting material.
