Scientists will advance to produce abundant singga from biomass gas.

The production of hydrogen from biomass is gaining attention, and thermal methods have emerged as the most widely adopted approach. Among these, steam gasization stands out as a particularly promising method for producing H2 rich Singa.

However, the main challenge related to the gasization process is the formation of TAR, causing device corrosion and pipeline obstruction, which can significantly lose the overall efficiency of the process.

It has been proven that the addition of a catalyst that is being gasized is effective in strengthening the cracks and hydrogen production of tar. In addition, it has been observed to promote the production of H2 rich synthetic gases in biomass such as alkali and alkali Earth Metal (AAEMS). However, a further research is needed to reveal how AAEMS affects gas production and the mechanism behind various metals.

In order to work on these issues, a research team led by Professor Yin Jiao of the New Jiang Technical Physical Physics Institute of the Academy of Science has developed a series of NI/CAO-CA12AL14O33 catalysts. The team has made a major progress in improving these catalyst stability.

This study is published in Journal Energy.

The experimental results show that the NI/CA3ALO catalyst demonstrated excellent catalytic performance and cyclic stability. Hydrogen yields and concentrations in synthetic gas were measured at 30.08 mmol/gbiomass and 60.61 vol % during the first reaction. In particular, after 10 cycles, the minimum carbon sediment and the slight sintering were observed on the catalytic surface.

Catalyst’s remarkable reversal performance is mainly due to its unique blade -like form, which effectively strengthens metal carriers, which prevents the aging of Oswald.

This study provides a new nickel -based catalyst design and a theoretical foundation for these applications in hydrogen production from biomass catalytic gasization.

In addition, inhibition of thread -shaped carbon formation by CA12AL14O33 in a carrier and suppression of encapsulated carbon precursor via calcium doping contributed to the resistance of the catalyst for carbon accumulation.
