alternative balanced equation for the cracking of decane

Name the catalyst involved in cracking 5. Name the 2 conditions needed for cracking. Why do you think the long-term costs are low Catalysts. Polymers are very large molecules made when many smaller molecules join together, end-to-end.Ĭatalysts are often expensive metals, e.g. Label the apparatus 1 ) What are the conditions needed for cracking to take place 2) What type of reaction is taking place 3) Describe the test for alkenes. While the practical is being carried out, make careful observations to be able to answer these questions. Some of the smaller molecules formed by cracking are used as fuels, and some of them are used to make polymers in plastics manufacture.Ĭonditions for cracking: 1.High temperature (300 o C) 2.Use a catalyst (aluminum oxide). This breaks chemical bonds in the molecules, and forms smaller hydrocarbon molecules.

Ing Decane Word Equation Cracker Heat ToĬatalytic cracker Heat to vaporise Distillation tower pressure Big Molecules Smaller molecules Molecules break up.Īn example of such a reaction is: C 8 H 18 C 6 H 14 C 2 H 4 ethene Octane hexane Ethene is used to make plastics Heat pressure catalyst Used as a fuel.Ĭrude oil often contains too many large hydrocarbon molecules and not enough small hydrocarbon molecules to meet demand - this is where cracking comes in.Ĭracking is a useful process that converts useless heavy fractions into smaller useful small ones.įractions containing large hydrocarbon molecules are vaporised and passed over a hot catalyst.

The small molecules produced are then separated by distillation. If you wish to download it, please recommend it to your friends in any social system. ScienceDirect is a registered trademark of Elsevier B.V.

Ing Decane Word Equation Cracker Heat ToĪn index of CRSE is proposed to define contribution ratio of supercritical extraction to the activity of the HZSM-5 catalyst in the developed kinetics model, and it is found that the CRSE increases with increasing hydrocarbon feed rates and decreasing catalytic activities, and reaches maximum value when the coke formation rate equals to the coke removal rate by supercritical hydrocarbon.Ĭiting articles Article Metrics View article metrics About ScienceDirect Remote access Shopping cart Advertise Contact and support Terms and conditions Privacy policy We use cookies to help provide and enhance our service and tailor content and ads.
