“…The catalyst is embedded over an inert cordierite support to reduce the thermal intensity of the reaction, as suggested by Chen et al The bulk density was set to 1600 kg/m 3 and the required catalyst for the desired conversion was 0.64 kg/tonne of ethylene. Recent literature states that there is limited understanding of the catalyst, due to its complexity, and hence, this study does not consider pellet geometry or dimensions for modeling.…”

Ethylene is a fundamental feedstock for the petrochemical industry. Globally, most production of ethylene is carried out by steam cracking of oil and gas at high temperatures (500–1100 °C). This is a well-established technology with a high environmental impact, relatively low yield, and a wide range of byproducts. In recent years, oxidative dehydrogenation (ODH) of ethane has been investigated as an alternative to achieve a more sustainable route through lower reaction temperatures (<500 °C) and hence lower energy consumption. This study consists of a comprehensive evaluation of an ODH plant design for ethylene production at a capacity of 500 kt/year. Two key process enhancements were applied using process simulation: heat integration with a refrigeration system and energy recovery through a Rankine cycle. Furthermore, an economic sensitivity analysis was performed to assess the impact on NPV by varying the feedstock cost, product selling price, CAPEX, OPEX, and capacity utilization for a range of plant sizes from 250 to 1000 kt/year. As a result, the design showed its robustness to ethane price variation, up to 134% increase. However, it was sensitive to ethylene price variation, up to 23% decrease. It also showed up to 8% OPEX savings with respect to the base design. The NPV was increased by 33% when applying the enhancements. In the environmental aspect, a 42% reduction in carbon intensity was achieved when compared to steam cracking, and the E-factor was 0.7 kg of waste per kg of product.

Rapid advancements in renewable energy and the staggering environmental impact of ethylene production have made the quest for "green ethylene" urgent. This Review explores traditional and emerging methods for ethylene production, focusing on the transition from conventional to electrified processes. The global importance of ethylene industry, valued at $230 billion, cannot be overlooked. However, its significant contribution of 150 million t of annual CO 2 emissions necessitates adopting carbon-negative and sustainable approaches. The declining cost of renewable energy has sparked interest in electrified processes, including electric crackers and electrochemical reactors for ethylene production. This Review provides a balanced overview of the performance attributes of conventional reactors, such as conversion, selectivity, and operating temperatures, and the crucial features of electrochemical reactors, including Faradaic efficiency and current density. Operating electrochemical reactors poses their own challenges, such as corrosion and lower energy efficiencies, which are discussed in detail. The Review also examines the economic aspects of "green ethylene" production, identifying challenges and opportunities. A comprehensive roadmap is presented to meet the global production scale of green ethylene. This roadmap outlines the steps needed to transition from conventional to electrified processes, ensuring a sustainable and environmentally friendly future for ethylene production. In summary, we emphasize the urgent need for carbon-negative ethylene production and provide transition pathways from conventional to electrochemical processes. The Review also provides insights into the performance attributes of different reactors, discusses their challenges, and presents an economic analysis.

“…Despite substantial progress, especially in the synthesis of catalysts with high activity and stability, several issues remain to be addressed. Traditional preparation methods such as precipitation/co-precipitation [3], calcination [4], sol-gel [5], flow chemistry [6,7], chemical deposition [8], etc typically entail a series of steps, requiring tedious and timeconsuming pre-/post-treatments such as washing, drying, calcination, reduction in hydrogen gas and activation. Meanwhile, such methods often need large volumes of solvents, which inevitably bring contaminants (Cl − , -SO 4 2 , -NO 3 , etc) and pollutants to the catalysts as well as the environment.…”

In this study, Ag/γ-Al2O3 catalysts were synthesized by an argon DBD plasma using silver nitrate as the Ag source and γ-alumina (γ-Al2O3) as the support. It is revealed that plasma can reduce silver ions to generate crystalline silver nanoparticles (AgNPs) of good dispersion and uniformity on the alumina surface, leading to the formation of the Ag/γ-Al2O3 catalysts in a green manner without traditional chemical reductants. The Ag/γ-Al2O3 exhibited good catalytic activity and stability in CO oxidation reactions, and the activity increased with the rise of the Ag content. For the catalysts above 2 wt% Ag content, 100% CO conversion level can be achieved at 300 °C. The catalytic activity of the Ag/γ-Al2O3 catalysts is also closely related to the size of the γ-alumina, where Ag/nano-γ-Al2O3 catalysts demonstrate better performance than Ag/micro-γ-Al2O3 catalysts with the same Ag content. In addition, the catalytic properties of plasma-generated Ag/nano-γ-Al2O3 (Ag/γ-Al2O3-P) catalysts were compared with the Ag/nano-γ-Al2O3 catalysts prepared by the traditional calcination approach (Ag/γ-Al2O3-C), in which the plasma-generated samples demonstrate overall better performance. This simple, rapid, and green plasma process is considered to be applicable for the synthesis of diverse noble metal-based catalysts.
