Because it has no negative impact on environment, nowadays, dimethyl ether (DME) has been received many attention. DME can be produced by methanol dehydration over a solid acid catalyst. The new nano-sized porous -Al2O3 with high surface area, high activity, and appropriate acidity was prepared for this purpose. The synthesized catalyst was successfully tested in the fixed bed reactor for production of DME from Methanol. The experimental procedure and other scientific works in this field has been completely explained in this book. The book is strongly suggested to the researchers of the...

In this book, the utilization possibility of nickel oxide nanoparticles-modified diatomite (NONMD) has been studied as an adsorbent for the removal of Colored Pollutants from an aqueous medium in the industrial effluent . Nickel metal can be a good choice for degrading the dyes and other pollutants from aqueous solutions . The equilibrium and kinetics study are investigated and the effects of various process parameters such as solution pH, adsorbent dosage, adsorbent size, initial dye concentration, temperature, contact time and salt were examined. The mean size and the surface morphology of...
