Abstract: Catalysts for converting carbon dioxide and methane to synthesis gas include an alumina supported copper-nickel alloy composition having the formula NixCuy. The catalyst comprises about 70% to about 98% by weight of alumina in the catalyst, wherein x is an atomic percentage nickel content and y is an atomic percentage copper content, and wherein a ratio of x to y is about 3:1 to about 10:1. In one embodiment, the Ni—Cu catalyst composition according to the present disclosure is derived by state of the art electronic structure calculations based on Density Functional Theory (DFT).

Abstract: Methods for fabricating thermally stable reducible metal oxide catalyst support structures on a base material using a multi-step incipient wetness impregnation (IWI) process are disclosed. For example, reducible metal oxide catalyst support structures having high surface area and high thermal stability may be formed using a multi-step IWI process, where the support structure is generated through high-temperature calcination between IWI steps. The metal or metal oxide catalysts fabricated using the methods are also disclosed. The generation of engineered surface defects on reducible metal oxides using a gas reduction process to serve as anchoring sites for metal or metal oxide catalysts is also disclosed. Generating engineered defects through a gas reduction process may be a relatively low-cost and scalable process suitable for fabricating efficient catalysts using a wide range of materials.

Abstract: A method for preparing p-xylene is provided. Raw materials containing methanol, naphtha and CO2 are introduced into a reactor filled with a catalyst for a reaction to produce p-xylene. By adding the methanol, the product distribution is adjusted, and the selectivity of p-xylene is obviously improved. In addition, components containing benzene and toluene in aromatic hydrocarbon products are returned to a reaction system and co-fed with the raw materials for a reaction to produce p-xylene, so that cyclic utilization of the raw materials is achieved, and the method has extremely high economic benefits. The method has a simple process and high feasibility, can greatly improve the selectivity and yield of p-xylene, has an important application value, and provides a new way for large-scale utilization of CO2.

Abstract: The addition of small amounts of alkaline earth metal oxides (CaO, MgO) as the isomerization function and transition metal oxides (such as MoO3, WO3) as the metathesis function significantly enhances the production of propylene using zeolites. Once the light olefins are formed by cracking on the acid sites of the zeolite, the 1-butene molecules undergo isomerization catalyzed by alkali earth metal oxides and then react with ethylene to produce more propylene.

Abstract: A reverse water-gas shift catalyst that can be used at high temperatures is obtained. A reverse water-gas shift catalyst (cat1) is produced by executing an impregnation-supporting step of impregnating a carrier (cb1) containing alumina as a main component with nickel as a catalytically active component (ca1) to be supported on the carrier, and calcinating a precursor obtained in the impregnation-supporting step at a temperature of 500° C. or higher.
