Petrochemical Industry
The challenges
Constraints in feedstock with respect to availability, quality & cost
Eco friendly processes & products: stringent emission levels- Preserving
the environment
Need for conserving energy
Waste minimization/effective treatment
Catalysts with higher efficacy: activity/selectivity/ life / Max.atom
efficiency
Process improvements: milder conditions/fewer steps
Ever-increasing demand for niche /specialty products at affordable prices
New catalysts /processes: Reduction in discovery & process
development cycle time

Olefin metathesis
C2H4 + C4H8  2 C3H6
Can be a stand alone unit or integrated with cracker/FCC unit
Low investment, less energy intensive, attractive returns
High propylene/ethylene yield ratios, varying from 0.5 to 1.1
Use of low cost C4 stream

Introduction
The use of biomass and carbon-based waste in the production of plastics can
contribute to the depletion of greenhouse gas (GHG)
The price of ethylene is being highly dependent on the price of crude oil
