cobalt
the catalyst is used inside the reactor to activate the reaction of the ethylene and oxygen in order to produce ethylene oxide EO. those catalyst are small Wight balls fit inside the reactor tubes and by passing combined gases (oxygen, ethylene, nitrogen, and some other gases) they will react in a maintained temperature and pressure then form the EO. There are two types of catalyst: high selectivity catalyst low selectivity catalyst i wish that i answered the question & glad to answer any further question.
starch can be used as support. homogeneous metal catalyst can be immobilised on starch.
Such chemicals are called as catalysts. Example:- Nickel metal is widely used as a catalyst.
Iron is one of the magnetic metal. It is used as a catalyst in Haber process to produce ammonia N2 + 3H2 ----------- 2NH3
Atactic and syndiotactic polymerization.
Traditionally Ziegler-Natta catalyst (TiCl3 or TiCl4 along with aluminium based co-catalyst) was used for olefin polymerization. But in recent years a variety of other complexes containing metals like aluminium, nickel, zirconium, ruthenium, iron, cobalt, hafnium, yttrium, titanium, vanadium, etc have also been employed as catalysts for olefin polymerization.
It varies due to the application of the polymer. For example, ethylene polymerization uses Cobalt as a catalyst. But other reactions for different final products require different catalysts, due to a difference in activation energy, and final properties desired.
Because water is used as a catalyst in preparation of other product of ethylene

Either addition polymerization or substitution. See also the link below.

nickel is the catalyst which is used in the formation of banaspati ghee
Ethylene is a hydrocarbon that is commonly found in plants since its main function is being a hormone for plants. This product is also used to ripen fruits.

Platinum is used as the catalyst in a catalytic converter, because this is a precious metal they can be very expensive.
