Abstract:
Iranian researchers at Kashan University and Research Institute of Petroleum Industry (RIPI) separated hydrogen from methane with an efficiency of 99.99% by hybrid synthesizing of a nanoadsorbant.

Iranian Researchers Separate Hydrogen from Methane with 100% Efficiency

Tehran, Iran | Posted on July 4th, 2012

Hydrogen has numerous applications in various fields, among which is the use of hydrogen in hydrocracking process.

No source has so far been known in order to obtain pure hydrogen. In order to fulfill the needs of industry, this material is prepared by using water-gas substitution (WGS) reaction through chemical processes. Therefore, the raw materials and the products except hydrogen must be separated from hydrogen in order to obtain pure hydrogen. Since methane is the raw material of the reaction, hydrogen should first be separated from methane, and then it should be transferred to other processes.

The researchers studied the deposition of carbon nanostructures on the active carbon made of walnut shell (which was chemically activated by using KOH). Results of the experiment showed that methane adsorption increased 17.92% for the deposition of nanofiber carbon on the active carbon. However, the increase in methane adsorption did not affect the amount of hydrogen adsorption.

Their experiments also showed that the carbon adsorbent hybridized by carbon nanofibers can separate a mixture of methane and hydrogen with equal concentrations of the compounds up to 99.99, and the outlet gas contained 99.99% pure hydrogen. Commercial adsorbents can purify hydrogen up to 73.80% at standard conditions.

The results of the research have been published in the February 15 edition of the Chemical Engineering Journal.
