Scientists develop efficient multifunctional catalyst for CO2 hydrogenation to gasoline

02.05.2017

Converting CO2 from a detrimental greenhouse gas into value-added liquid fuels not only contributes to mitigating CO2 emissions, but also reduces dependence on petrochemicals.

However, since CO2 is a fully oxidized, thermodynamically stable and chemically inert molecule, the activation of CO2 and its hydrogenation to hydrocarbons or other alcohols are challenging tasks. Most research to date, not surprisingly, is focusing on selective hydrogenation of CO2 to short-chain products, while few studies on long-chain hydrocarbons, such as gasoline-range (C5-C11) hydrocarbons. The key to this process is to search for a high efficient catalyst.

The research team led by Dr. SUN Jian and Prof. GE Qingjie in Dalian Institute of Chemical Physics, has succeeded in preparing a high efficient, stable, and multifunctional Na-Fe3O4/HZSM-5 catalyst for the direct production of gasoline from CO2 hydrogenation.

This catalyst exhibited 78% selectivity to C5-C11 as well as low CH4 and CO selectivity under industrial relevant conditions. And gasoline fractions are mainly isoparaffins and aromatics thus favoring the octane number.

Moreover, the multifunctional catalyst exhibited a remarkable stability for 1,000 h on stream, which definitely has the potential to be a promising industrial catalyst for CO2 utilization to liquid fuels.

In-depth characterizations indicate that this catalyst enables RWGS over Fe3O4 sites, olefin synthesis over Fe5C2 sites and oligomerization/aromatization/isomerization over zeolite acid sites. The concerted action of the active sites calls for precise control of their structures and proximity.

This study paves a new path for the synthesis of liquid fuels by utilizing CO2 and H2. Furthermore, it provides an important approach for dealing with the intermittency of renewable sources (sun, wind and so on) by storing energy in liquid fuels.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
