Ko te maaramatanga whanui mo te reactor he ipu me nga tauhohenga tinana, matū ranei, a na roto i te hoahoa hanganga me te whirihoranga tawhā o te ipu, ka taea e ia te whakatutuki i te whakamahana, te whakaetonga, te whakamatao, me nga mahi whakaranu iti-tere e hiahiatia ana e te tukanga. .
Ka whakamahia nuitia nga reactors ki nga mara penei i te hinu, matū, rapa, pesticides, waikano, rongoa, me te kai. He oko pehanga enei hei whakaoti i nga mahi penei i te whakangao, te nitrification, te hydrogenation, te alkylation, te polymerization, me te condensation.
