Hydrogen Production VIA Polyoxymethylene Degradation using Copper Nanocatalysts
نویسندگان
چکیده
Polyoxymethylene (POM) is an engineering thermoplastic. Formaldehyde is the monomer unit of this polymer. Depolymeraization of POM occurs at 100 o C and yields formaldehyde whereas thermal degradation occurs at 270 o C. During thermal degradation, POM splits into carbon dioxide, water and formic acid. It has been proved that formaldehyde can be used as hydrogen source, when metallic nanoparticles are used as catalysts under particular parameters. In this experiment a trial has been made to produce hydrogen using POM scrape material. POM is used as formaldehyde source and copper nanoparticle is used as catalyst to produce sodium formate and hydrogen. Water is used as solvent for formaldehyde. Depolymeraization is done with water at 100 o C. The quantity of hydrogen produced is calculated based on sodium formate assay and statistical analysis. Sodium formate in different weights is taken for assay to measure precision, correlation coefficient and regression analysis.

Pristine complex quaternary hydride (LiBH4/2LiNH2) and its destabilized counterpart (LiBH4/2LiNH2/nanoMgH2) have recently shown promising reversible hydrogen storage capacity under moderate operating conditions. The destabilization of complex hydride via nanocrystalline MgH2 apparently lowers the thermodynamic heat values and thus enhances the reversible hydrogen storage behavior at moderate te...
