AI Technical Summary
Technical Problem
Existing Ni-based catalysts are prone to carbon buildup due to sintering of active components at high temperatures, which reduces catalytic performance. Furthermore, the dry reforming reaction of methane poses safety risks and is difficult to industrialize.
Method used
NiMo-ADM catalysts were prepared using dielectric barrier discharge plasma technology. Through hydrothermal treatment and calcination, highly active and stable zeolite catalysts were formed, which promoted metal-support interaction and surface oxygen vacancy defects.
Benefits of technology
The prepared NiMo-ADM catalyst operated stably at high temperature for 100 hours without deactivation, improving the efficiency and safety of the methane dry reforming reaction and realizing efficient syngas production.

Abstract
This invention belongs to the field of methane dry reforming catalyst technology, specifically relating to a method for plasma-assisted preparation of zeolite catalysts and its application. The specific preparation steps are as follows: attapulgite powder is mixed with an acid solution and then hydrothermally treated to obtain treated attapulgite powder; the treated attapulgite powder and tetrapropylammonium hydroxide are dissolved in an alkaline solution, hydrothermally treated, and then calcined to obtain attapulgite-based zeolite; the attapulgite-based zeolite and tetrapropylammonium hydroxide are dissolved in deionized water to prepare a mixed solution; a nickel ethylenediamine complex solution and a molybdenum ethylenediamine complex solution are added to the mixed solution, and after hydrothermal treatment, a NiMo-ADM precursor is obtained; the precursor is subjected to DBD plasma treatment and then calcined to prepare the zeolite catalyst. This invention features simple process and low cost, preparing a highly active and stable non-precious metal catalyst through a simple synthesis method, achieving efficient methane dry reforming.
