Tuning of catalytic behaviors in ethanol dehydration with oxygen cofeeding over Pd-HBZ catalyst for ethylene production at low temperature

Design of an integrated biorefinery for bioethylene production from industrial forest byproducts

“…18 The optimization of the process lines of biorefineries encompassing technical, environmental, and economic aspects has been the subject of intense research in recent years. [19][20][21][22] These studies highlighted that more studies are needed to (i) reduce costs of enzymatic hydrolysis by improving the conversion process of lignocellulosic material to fermentable sugars, 23 (ii) optimize bioethanol production technology, 20 (iii) use of less purified bioethanol for cost and energy savings, 20 (iv) reduce the influence of impurities in bioethanol on the efficiency of the catalytic process of ethylene production, 20 (v) develop of catalysts for bioethanol conversion to ethylene at low temperature. 21 Ethylene production costs and yield widely vary depending on the lignocellulosic raw material selected and on the location of the plant.…”

Production of Acetaldehyde via Oxidative Dehydrogenation of Ethanol over AgLi/SiO2 Catalysts

“…A wide spread of catalytic systems including Al2O3, TiO2, SiO2, clay, zeolite-based catalysts, and others for effective conversion of ethanol to higher valve products was investigated [17,[21][22][23]. Across various catalysts investigated, balancing/controlling the available acid-base sites on the catalyst surface has been recognized as the key design metric for controlling the selectivity of desire products.…”

The role of ruthenium on the acidity of mixed alumina and silica phases and its impact on activity for ethanol dehydration

“…[7,16,17] A common theme in this work is the modification of the acid catalysts to adjust the active site activity towards ethanol dehydration. [7,18,19] This is because the distribution of weak, moderate, and strong acid sites regulates catalytic performance. Furthermore, a small amount of metal can act as a promoter to enhance the catalytic reaction or open new kinetic pathways for ethanol conversion.…”
