Natural gas can be used as fuel for generating electricity, heating and powering transportation. It is also the raw material to manufacture hydrogen and ammonia.<\/strong><\/p>\n\n\n\n

Currently, biogenic and thermogenic processes are the two widely accepted methods for natural gas production. Whereas, high content of CO2<\/sub> in gas products is inevitable during these processes, which cannot satisfy the composition requirements of pipeline natural gas.<\/p>\n\n\n\n

A research group led by Prof. LU Fang from the Dalian Institute of Chemical Physics<\/a> (DICP) of the Chinese Academy of Sciences (CAS) proposed an efficient catalytic approach to directly transfer solid biomass into natural gas with low carbon footprint. This study was published in Nature Communications<\/em><\/a> on January 11.<\/p>\n\n\n\n

The researchers prepared a robust catalyst with Ni2<\/sub>Al3<\/sub> alloy phase, achieving nearly complete conversion of various agricultural and forestry to natural gas. In the conversion process, the total carbon yield of gas products reached up to 93% after several hours, and the catalyst showed powerful processing capability for the production of natural gas during 30 cycles.<\/p>\n\n\n\n

“Life cycle assessment revealed that the life cycle primary fossil energy depletion and greenhouse gas emissions in this process could be reduced by 26% and 34%, respectively, compared to the fossil-natural gas,” said Prof. LU.<\/p><\/blockquote>\n\n\n\n

What’s more, bio-natural gas produced from the combined hydrogen with lignocellulosic biomass can be further applied in industry, transportation, and electric power plant by the existing transportation pipelines.<\/p>\n\n\n\n

This study provides a new guidance for the catalytic transformation of raw biomass. It was supported by the Natural Science Foundation of China, the National Key R&D Program of China, the Strategic Priority Research Program of CAS, and DICP Grant.<\/p>\n\n\n\n
