WebA heat-integrated packed-bed membrane reactor is studied based on detailed, transient 2D models for coupling oxidative and thermal propane dehydrogenation in one apparatus. The reactor is structured in two telescoped reaction zones to figure out the potential of mass and heat integration between the exothermic oxidative propane dehydrogenation (ODH) in … WebNov 10, 2010 · When the models by Sundaram and Froment [10, 11] for coke formation are coupled with mechanisms that predict ethane and propane cracking, R 2 and R 4 are used with the concentration of C4+ (that represents hydrocarbons with four or more carbons) and propylene to simulate coke deposition. halfords newhaven east sussex

WebCracking is the process of breaking down hydrocarbons into smaller hydrocarbons. Broadly speaking, there are two types of cracking: thermal cracking and catalytic cracking. But for the application here, it doesn’t matter which one we’re using. Let’s take a quick look at our starting material, nonane. WebDec 31, 1979 · Abstract A novel experimental set up for determining the kinetics of coke deposition in thermal cracking is described and its application to the cracking of propane is illustrated.
