hi my friends, am Arabian man  and am study in an university, nowdays i am doing project in designing styrene plant by using Co2 as soft oxidative

i hope that if any one of u have any related books or websit or anythings that can help me just replay me.


thank u all

I believe you are refering to the SODECO₂ process.

SODECO₂ stands for Styrene from Oxidative Dehydrogenation via CO₂.

Although the actual composition of the catalyst is proprietary knowledge, I can tell you what the components are.

function	component 1	component 2
Active Phase	Fe3O4	V2O5
Activity Promoter	Mn	-
Stability Promoter	Mo	Sb
Structural Stabiliser	Ca, Mg	Mg
Catalyst Support	Promoted Al2O3, ZrO2	Promoted Al2O3, ZrO2

Below are the reference you would need:
- Catalyst for Dehydrogenating Aromatic Hydrocarbons with Carbon Dioxide, U.S. Patent 6, 034,032, U.S.Patent 6,037,511(2000).

The literature value for the selectivity of ethylbenzene to styrene for this catalyst is 96.5%.
