What is the use of ZSM-5?
Commonly used in converting methanol to gasoline and diesel as well as oil refining, ZSM-5 has proved superior to amorphous solid acid catalysts in reactions such as xylene isomerization, toluene disproportionation and toluene alkylation etc.
How is ZSM-5 made?
There are many ways to synthesize ZSM-5; a common method is as follows: an aqueous solution of silica, sodium aluminate, sodium hydroxide, and tetrapropylammonium bromide are combined in appropriate ratios. SiO2 + NaAlO2 + NaOH + N(CH2CH2CH3)4Br + H2O → ZSM-5 + analcime + alpha-quartz.
Why is zeolite a good catalyst?
Zeolites are also widely used as catalysts and sorbents. Their well-defined pore structure and adjustable acidity make them highly active in a large variety of reactions.
What is in the Pentacel vaccine?

What is zeolite used for in aquariums?
Zeolite is widely used in fish aquariums mainly to capture multiple undesirable contents in the water. This highly porous mineral absorbs undesirable elements from the water like a sponge absorbs water. It has a high affinity for ammonia, therefore, making it an extremely suitable media material for your aquarium.
Is Pentacel vaccine safe?
Becoming infected with diphtheria, haemophilus influenzae, pertussis, tetanus, or polio is much more dangerous to your child’s health than receiving the vaccine to protect against these diseases. Like any medicine, Pentacel can cause side effects, but the risk of serious side effects is extremely low.
