SAMCA’s TS-1 catalyst is used as oxidation catalyst using dilute hydrogen peroxide as an oxidant around the world by organic chemical industry as it has helped to achieve a primary goal of increase productivity at negligible or no waste generation. Following are some applications:
Oxidation reactions catalyzed by TS-1 are shown in the figure below:
The catalyst is available in 25 and 50 kg packs in HDPP drums. For laboratory evaluation the catalyst can be supplied in 100 g to 1 kg scale in small plastic containers.
All data are based upon our Partner’s standard test methods, and all test methods are available upon request.
SAMCA’s ZSM5 is a typical high silica Zeolite with MFI-type structure which makes it widely useful as catalysts in petroleum and petrochemical industry. SAMCA’s ZSM5 is also used as a catalyst for the synthesis of specialty and fine chemicals, such as the preparation of ethylene amines.
ZSM5 zeolite is a microporous solid catalyst and it can be synthesized in an extensive range of SiO2/Al2O3 ratios and it is obtained in different chemical or cationic from viz. NH4-ZSM5, Na-ZSM5, H-ZSM5, Fe-ZSM5, Cu-ZSM5 etc.
ZM0P catalysts are available in various forms such as powders, extrudes, pellets and spheres
1. | SiO2(%) | = 97.0 ± 3.0 |
2. | Al2O3 (%) | = ≥ 6.0 |
3. | Na2O(%) | = ≤ 0.02 |
4. | SiO2: Al2O3 Mole Ratio | = 40.0 ± 5.0 |

2. | Moisture | = ≤ 10.0 |
3. | Surface Area (m2/g) | = 420 ± 60 |
4. | Crystallinity (%) | = ≥ 95 |
5. | Diameter of extrudes (mm) | = 1.5 & 3.0 |
6. | Crushed strength (N/m2) | = 50 - 55 |
ZM0P (i.e ZSM-5 type) zeolite is mainly used as catalyst for diesel hydro- dewaxing, One of the most popular applications of ZSM-5 Zeolite is “additive” for moving-bed FCC catalyst with SiO2/Al2O3 molar ratio 35 - 45.
Also, ZSM-5 Zeolite catalyst is used as shape-selective catalyst in many organic reactions, such as synthesis of ethylbenzene and isomerization of xylenes.
Using SAMCA ZM0E-40 catalyst with trace quantity of noble metal metal loading the isomerization of o-toluidine to thermodynamic equilibrium mixture of m-toluidine + p-toluidine + o-toluidine (unreacted) the reaction was carried out for more than 100 hours with no drop-in activity. Similarly, it is possible to isomerize p-toluidne or ortho + para- toluidines mixture to a mixture of three (orhto, para and meta) isomers.
Also, the ZM0E-40 catalyst is used for isomerization of o-cresol or ortho + m-cresol to mixture of o-cresol + m-cresol + p-cresol with better conversion and selectivity.
The catalyst is reusable in the above-mentioned isomerization reactions for multiple cycles.
The catalyst is available in 25 and 50 kg packs in HDPP drums. For laboratory evaluation the catalyst can be supplied in 100 g to 1 kg scale in small plastic containers.
All data are based upon our partner’s standard test methods, and all test methods are available upon request.
SAMCA ZS0P i.e. Silicalite is a typical high silica zeolite (nil Al) with MFI-type three dimensional structures with pore size of approximate 5.5 Å.
ZS0P catalysts are available in various forms such as powders, extrudes, pellets and spheres
1. | SiO2(%) | = ≥ 99.5 |
1. | Appearance | = White Powder |
2. | Moisture | = ≤ 5.0 |
3. | Surface Area (m2/g) | = 450 ± 50 |
4. | Crystallinity (%) | = ≥ 95 |
5. | Average Particle Size (µm) | = 20 ± 5 |
Using ZS0P catalyst on Oxidation of Styrene, Styrene Oxide is obtained as a major component while also producing small quantities of Phenyl acetaldehyde (PAA) which is also a useful by-product. The Conversion of Styrene is in the range of 90-95% and selectivity towards Styrene Oxide plus Phenyl acetaldehyde is 95%.
The deactivated catalyst is regenerated by a standard procedure established and perfected by our partner company. The regenerated catalyst is further tested for 2 more cycles and found to give almost similar level of conversion and selectivity as that observed with a fresh catalyst.
The catalyst is available in 25 and 50 kg packs in HDPP drums. For laboratory evaluation the catalyst can be supplied in 100 g to 1 kg scale in small plastic containers.
All data are based upon our Partner’s standard test methods, and all test methods are available upon request.
