Catalysts and substrates
We sell catalyst by the pound. Anything from 1 pound to 10,000 lbs. Generally speaking we can ship in 1 to 3 days from our receipt of your order.
You've got to be a little careful when you order catalyst for an atmosphere generator. Because cube is less expensive than spherical there's always a temptation to order the less expensive cube. However, there are big differences in what's called "packing density" and surface area between cube and spherical configurations.
If the equipment, in which you're going to use the catalyst, is not being run anywhere near capacity you may be able to use cube type without problem. If, on the other hand, your equipment is being operated at or near capacity then stick with the spherical.
Conversly, if you have equipment originally designed to use cube type catalyst and you're running out of capacity you may (if you're a little lucky) be able to squeak some additional throughput from your equipment by going to spherical catalyst.
We inventory catalyst in the following configurations:
CATALYST SUBSTRATE, 1-1/4" NOMINAL (ALUNDUM)
CATALYST SUBSTRATE, 3/4" NOMINAL DIA
CATALYST, IRON OXIDE, 1/2" SPHERE
CATALYST, IRON OXIDE, 3/4" SPHERE
CATALYST, IRON OXIDE, 3/4" CUBE
CATALYST, NICKEL 1" CUBE
CATALYST, NICKEL, 1/2" SPHERE
CATALYST, NICKEL, 3/4" CUBE
CATALYST, NICKEL, 3/4" SPHERE
The term "substrate" refers to the material upon which the catalyst is applied. It's non-reactive and contributes nothing to the cracking process. Other than providing a matrix surface for the catalyst, substrate is sometimes used as a bed material. A layer of substrate is placed in a retort or vessel and the catalyst is placed on top of the substrate bed.
In addition to the above we can also provide a ceramic bed material consisting of 1/2" nominal diameter ceramic spheres. Shipment of this material can usually be made within 2 weeks ARO.
The bed material (either substrate or ceramic) is usually used in gas fired endothermic generators where it is desirable to keep the catalyst off the bottom and up in the hot section of the retort in order to minimize fouling. It also permits a little additional heating of the gas to be cracked as it passes through the bed material.
