A catalyst for the direct reforming of methane and simulated biogas has been prepared using a green and low temperature hydrothermal method. The nickel and iron codoped SrZrO3 perovskite shows catalytic activity comparable to 10% Ni/Al2O3, but with an almost 50% saving in nickel content and a significant reduction in unwanted carbon deposition through thermal decomposition of methane and the Boudouard reaction. The use of a catalyst with a low active metal content produced via a hydrothermal route provides an attractive and sustainable method of production of synthesis gas from both methane and biogas for potential use in solid oxide fuel cells.

In the present paper, many unsaturated polyesters has been synthesized using maleic anhydride, phthalic anhydride and succinic anhydride for esterification with new monomer [E)-1-(4-hydroxyphenyl)-3-(3-methoxy-4-hydroxyphenyl) prop-2-en-1-one]. These polyesters were polymerized by condensation reaction . Their chemical structures were characterized using FTIR, 13C-NMR and 1H NMR spectroscopy. Thermal properties have been analysed using Differential Scanning Calorimetry of synthesized polyesters .All the polymers showed well thermal stability and perfect data of glass transition temperature (Tg) also the results showed polyesters and monomer were successfully synthesized by giving well spectrum improved existing an ester functional group (-COO-) in spectrums each polymer prepared also existent Chalcone functional group(-CO-CH=CH-) in spectrum of monomer.
