Nano catalysts to address challenging catalysis reactions in the chemical industry
Updated: May 23, 2015 01:50:54pm
New Delhi, May 23 (KNN) Council of Scientific and Industrial Research - Indian Institute of Petroleum (CSIR-IIP) has developed new energy efficient synthesis strategies for preparation of various nano structured material (nano-catalysts), useful for several challenging catalysis reactions.
It developed nano-catalysts useful in reactions namely - Selective Oxidation of Benzene to Phenol and Selective Oxidation of Propylene to Propylene Oxide (PO).
For Selective Oxidation of Benzene to Phenol, CSIR-IIP used an environmentally benign green process with economic efficiency. It has developed a nano catalyst which directly converts benzene to phenol in presence of air in a continuous process with very high selectivity.
For Selective Oxidation of Propylene to Propylene Oxide (PO), a nano catalyst is developed which helps in adopting a new process of selective oxidation of propylene to PO, in an economically viable and more environment-friendly means, with minimal waste.
Propylene oxide (PO) otherwise is an important synthetic intermediate used in the preparation of commodity chemicals, such as poly urethane foams, propylene glycol, polypropylene glycol and propylene carbonate.
Currently, its production exceeds 10 million tons per annum. Ninety per cent of the world production of PO is produced either through a chlorohydrins process or by an organic hydro peroxide process (Halcon method), which apart from having acute environmental problems also results in production of unwanted by-products.
Another nano catalyst developed at CSIR-IIP helps in Low Temperature Methane Activation.
The CSIR-IIP developed nano catalyst that can activate methane at low temperature at atmospheric pressure without any deactivation. This also helps in reducing carbon dioxide, another notorious greenhouse gas to produce synthesis gas (mixture of carbon monoxide and hydrogen).
CSIR-IIP also developed nano catalyst to convert Ethane to Ethylene in a continuous process at atmospheric pressure.
The controlled synthesis of nano particle by simple preparation method still remains a challenge for the researchers as most of the preparation methods are energy intensive, require substantial heat treatment and produce large particles. (KNN/ST)
