Polymer industryPolymer industry in Indonesia
Petrochemicals are chemical products derived from petroleum and other hydrocarbon sources.
Polymers are substances containing a large number of structural units joined by the same type of linkage. Polymer consists of combination of monomer

PolypropylenePolypropylene basic
polypropylene is a valuable polymer and is used as plastic for
making pipes, ropes, fibres, etc
It is manufactured by catalytic reaction in a stirred tank reactor, where Ti and aluminium halides are used as catalysts at a temperature of 60°C−70°C and a pressure of 1−2 MPa

Methanol-to-Propylene Technology
two reaction steps
1. Methanol dehydration to DME on an aluminium catalyst2. Transforming DME or methanol into a variety of olefins. The use of ZSM-5
catalyst yields propylene. Propylene will be processed further into polypropylene
