Dynamic hydrogen-intensified methanation of synthetic by-product gases from steelworks

Carbon Dioxide Methanation for [4] Intensified Reactors

Low but Intensified Product Diversification

The expansion of transportation and high-speed communication networks throughout the world has increased the export opportunities of Middle East and North Africa (MENA) producers. It has also increased competition for the region's producers by helping companies in other countries and regions export to world markets as well. Countries in the MENA region occupy a place midway up the ladder of com...

Adsorption of Cr(III) and Mg(II) from Hydrogen Peroxide Aqueous Solution by Amberlite IR-120 Synthetic Resin

In concentration of hydrogen peroxide, first, the solution should be quite pure, and then, it concentrate with methods such as vacuum distillation and cooling crystallization, because impurities in the hydrogen peroxide solution in high concentrations are causing decomposition of this substance; that is very dangerous. The purpose of this article is separation of chromium and magne...

Analysis of Stack Gases Discharged From Synthetic Fiber Finishing

Stack and duct analyses have been conducted on textile finishing ranges processing cottrn and synthetic fibers. Analytical methods used include gas chromatography, infrared spectroscopy and gravimetric analysis. Synthetic fiber spin finish, knitting lubricanis and cotton resin finishes were identitied in stack samples. When particulate loading was of interest, isokinetic samples of the stack ga...

dynamic coloring of graph

در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...
