Heterogeneous vs. Homogeneous Catalysis: Comparative Insights and Breakthroughs
Abstract: Catalysis, a pivotal process in chemical reactions, can be classified into two main types: heterogeneous and homogeneous catalysis. This comparative analysis delves into the distinctions, advantages, and breakthroughs in both domains. Heterogeneous catalysis, involving catalysts in a different phase than the reactants, is characterized by ease of separation and catalyst recovery, making it industrially favorable. Conversely, homogeneous catalysis, where catalysts and reactants share the same phase, offers superior selectivity and …

Use of Advanced (i.e., Membrane) Technology for the Wastewater Treatment of Coke Ovens
Abstract: Coke plants produce gas, and coke for metallurgical purposes and also supply the raw materials for the manufacture of dyes, drugs, and high explosives. Naturally found coal is converted into coke in coke ovens. A large quantity of water is used for quenching hot coke and for washing gas. After quenching the wastewater contains high-suspended solids, high biochemical oxygen demand (BOD) (600–1300 mg/L), chemical oxygen demand (COD) (1500–3000mg/L), phenols(500–650 mg/L), …

Green Manufacturing with Steel Swarf
Abstract: The industrial sector drives nearly one-third of global energy demand, with most of this energy used to produce bulk materials. However, the rate of recycling of metallic materials is much higher than non metallic ones, especially when the scrap is heavy. But in very loose swarfs the transformation rates are poor, and processes are unsustainable. To improve the life productivity of bulk materials, and also lower the specific energy consumption, …
