Activation of n-pentane while prolonging HZSM-5 catalyst lifetime during its combined reaction with methanol or dimethyl ether

Tomas Cordero-Lanzac et al.

Summary: This study investigates the synergies between oxygenates (especially dimethyl ether) and n-pentane at low OX/nC(5) ratios, enhancing n-pentane conversion while reducing catalyst coking rate. The analysis of used catalysts reveals that dimethyl ether exhibits higher reactivity than methanol in forming coke structures.

MAPO-18 Catalysts for the Methanol to Olefins Process: Influence of Catalyst Acidity in a High-Pressure Syngas (CO and H2) Environment

Jingxiu Xie et al.

Summary: The transition to decentralized chemical plants using distributed feedstocks requires simpler downstream unit operations. Through the study of a series of isomorphically substituted zeotype catalysts, it was found that M(II)-substituted MAPO-18s demonstrate superior performance in the methanol to olefins (MTO) reaction, and co-feeding experiments revealed the inhibiting effect of CO on olefin hydrogenation.

Efficient methanol dehydration to DME and light hydrocarbons by submicrometric ZrO2-ZSM-5 fibrillar catalysts with a shell-like structure

Jose Palomo et al.

Summary: In this study, a structured catalyst consisting of submicrometric fibrillar ZrO2 fibers with well-defined ZSM-5 zeolite aggregates was prepared by electrospinning technique. The catalyst showed high activity for the synthesis of DME and light olefins via methanol dehydration, and it could be easily structured inside a fixed-bed reactor, overcoming the limitations of mass and heat transfer. The selectivity to DME and light hydrocarbons could be controlled by tuning the zeolite loading in the catalyst.

Feasibility, Limit, and Suitable Reaction Conditions for the Production of Alcohols and Hydrocarbons from CO and CO2 through Hydrogenation, a Thermodynamic Consideration

Shujia Guo et al.

Summary: The conversion of CO and CO2 into valuable liquid fuels and chemicals through hydrogenation has attracted significant interest. This study evaluates the feasibility, limit, and suitable conditions for these reactions through thermodynamic considerations. Results show that the hydrogenation of CO/CO2 to alcohols, light olefins, and aromatics is thermodynamically viable under appropriate conditions. Although current conversion processes may be restricted by kinetic factors, it is important to ensure that the reactions are conducted under thermodynamically feasible conditions. These results help determine the suitable operation region for CO/CO2 hydrogenation and provide directions for optimizing catalysts and processes.

Role of Zr loading into In2O3 catalysts for the direct conversion of CO2/CO mixtures into light olefins

A. Portillo et al.

Summary: The effect of ZrO2 content on the performance of In2O3-ZrO2 catalyst in the hydrogenation of CO2/CO mixtures has been studied. The results show that controlling the Zr/In ratio can improve the conversion of CO2 and COX, enhance the selectivity of oxygenates, and prevent catalyst sintering. By using In2O3-ZrO2/SAPO-34 tandem catalysts, the conversion of COx can be increased by nearly 5 times, leading to a higher yield of olefins.

The roles of CO and CO2 in high pressure methanol synthesis over Cu-based catalysts

Niels D. Nielsen et al.

Summary: Experiments showed that CO2 is more favorable for methanol synthesis on Cu catalyst compared to CO. At low conversion conditions, CO has inhibiting effects, but as conversion is increased, a beneficial role of CO is observed. CO's beneficial role mainly comes from its promotion of the water-gas shift reaction, which helps to reduce the inhibitory effect of water on Cu-based catalysts.

Conditions for the Joint Conversion of CO2 and Syngas in the Direct Synthesis of Light Olefins Using In2O3-ZrO2/SAPO-34 Catalyst

Ander Portillo et al.

Summary: The study focused on the conditions for promoting the joint conversion of CO2 and syngas in the direct synthesis of light olefins, as well as the stability of the InZr/S34 catalyst. Suitable conditions were identified for the process, showing high olefin yield and selectivity under specific operating parameters. The low pressure and low H2/COx ratio in the process could potentially facilitate the integration of sustainable H2 production with PEM electrolyzers and the covalorization of CO2 and syngas obtained from biomass.

Global vision from the thermodynamics of the effect of the bio-oil composition and the reforming strategies in the H2 production and the energy requirement

Leire Landa et al.

Summary: The study compares the yield of H-2 and by-products in the reforming of different oxygenates in bio-oil through thermodynamic analysis, focusing on steam reforming, oxidative steam reforming, and autothermal reforming. The results show that S/C = 5 and the temperature range of 610-644 degrees Celsius are the most suitable conditions for high equilibrium H-2 yield. Inert gas addition at a S/C ratio of 1.5 slightly increases hydrogen yield and decreases coke formation, but this effect is not significant for S/C ratios above 5.
