WHAT IS H2S?


Nov 18, 2020

H2S is the chemical formula for the compound, hydrogen sulfide. It is made up of two hydrogen atoms and a single sulfur atom. It is a colorless, flammable, and extremely hazardous gas that has a pungent rotten-egg smell. H2S is produced by the bacterial breakdown of organic materials, as well as animal and human waste. […]

WHAT IS BIOFUEL?


Nov 18, 2020

Biofuel is a renewable energy resource produced from organic matter and waste, materials collectively known as biomass. Compared to other options, biofuel is eco-friendly and more renewable (Biofuels explained – EIA). Ethanol and biogas are just two types of biofuel, but there are many more in use today. ETHANOL Ethanol is produced via the process […]

What is Silica Gel?


Jun 12, 2020 ,

Silica gel is a solid form of silicon dioxide, or SiO2, and it is actually more granular and hard than it is a gel. Silica gel is specifically synthesized to be highly porous, which is what gives it its adsorbing capabilities. Additionally, SiO2 is a polar compound, which allows it to preferentially adsorb other polar […]

What Is Molecular Sieve?


May 15, 2020 ,

What is Molecular Sieve? Molecular sieves are synthetic zeolite materials engineered with pores of precise and uniform structure and size. This allows them to preferentially adsorb gases and liquids based on molecular size and polarity. Zeolites are naturally existing, highly porous crystalline solids, belonging to the class of chemicals known as aluminosilicates. There are four […]

Is Activated Alumina Harmful?


Apr 12, 2020 ,

Activated alumina, like most commercial desiccant material, is not harmful to people or the environment. Activated alumina is a porous solid made of aluminum oxide, or Al2O3. Though non-toxic, aluminum oxide is mildly irritating to skin and eyes with too much exposure. Please, do not eat. Fun Fact: The crystalline form of Al2O3 is attributed […]

What is Activated Alumina?


Mar 18, 2020 ,

Activated alumina is a porous, solid form of aluminum oxide, otherwise known as Al2O3 or alumina. This is the same mineral that makes up the precious gems ruby and sapphire, with impurities being the source of the stones’ bright colors. After activated alumina has been evacuated of existing moisture by heating it, the high surface […]

Is Silica Gel Polar?


May 12, 2017 ,

Is silica gel polar? What significance does this hold for its adsorption capabilities? Silica gel is a polar adsorbent. This allows it to preferentially adsorb other polar materials. When it comes to polarity, materials interact more with like materials. This principle is particularly important to many laboratories, which use silica gel as the stationary phase […]
