WebCatalytic cracking. Modern cracking uses zeolites as the catalyst. These are complex aluminosilicates, and are large lattices of aluminium, silicon and oxygen atoms carrying a negative charge. ... Steam cracking is useful … WebThermal cracking uses a high pressure and no catalyst. Catalytic cracking uses a slightly raised pressure and a zeolite catalyst. Thermal cracking can be done on larger alkanes and produces predominantly alkenes. Catalytic cracking cannot be done on very large hydrocarbons and produces mostly branched or cyclic alkanes.
