WebAlkenes can be used to make polymers and the hydrogen used to make ammonia. Kerosene and diesel oil are often cracked to produce petrol, other alkenes and hydrogen. Cracking involves heating the hydrocarbon molecules to around 600 – 700°C to vaporise them. The vapours then pass over a hot powdered catalyst of alumina or silica. WebCatalytic cracking. James G. Speight, in The Refinery of the Future (Second Edition), 2024 Abstract. Catalytic cracking is a conversion process that can be applied to a variety of feedstocks ranging from gas oil to heavy crude oil and residuum. The concept of catalytic cracking is basically the same as thermal cracking, but it differs by the use of a catalyst … dyon repeater

Cracking of Hydrocarbons (AQA GCSE Chemistry 9-1)

WebDec 1, 2015 · Thermal cracking takes place at high pressure and high temperature and produces a high percentage of alkenes (mechanism not required). Catalytic cracking takes place at a slight pressure, high temperature and in the presence of a zeolite catalyst and is used mainly to produce motor fuels and aromatic hydrocarbons (mechanism not required). WebNov 4, 2024 · Cracking long chain hydrocarbons into shorter alkanes and alkenes is a staple of the classroom. But if undertaken using traditional methods, this practical can lead to the dreaded ‘suck-back’ – should students heat for too long or forget to remove the delivery tube from the water at the end of the experiment.
