10	1.0	0.5
15	1.5	0.8

3. Corrosive environment

TAP catalysts exhibit excellent corrosion resistance in corrosive environments such as strong acids, strong alkalis and organic solvents. The following is the stability of TAP catalysts in different corrosive environmentsSex:

Environment	Corrosion rate (mm/year)
Concentrated Sulfuric Acid	0.01
Concentrated hydrochloric acid	0.02
Sodium hydroxide	0.03
Organic Solvent	0.05

Reliability Analysis

1. Lifespan and regeneration

The lifespan of the TAP catalyst is usually between 5000-10000 hours, depending on the operating conditions and reaction type. The catalyst will gradually become inactive during use, but its activity can be restored through appropriate regeneration treatment. The following are the regeneration properties of TAP catalysts:

Regeneration times	Activity recovery rate (%)
1	95
2	90
3	85
4	80

2. Operation stability

TAP catalysts exhibit extremely high stability during continuous operation. Even after long runs, the activity and selectivity of the catalyst remain at a high level. The following are the performance changes of TAP catalyst after 1000 hours of continuous operation:

Time (hours)	Conversion rate (%)	Selectivity (%)
0	99	95
500	98	94
1000	97	93

3. Anti-poisoning performance

TAP catalysts have high anti-toxicity ability to common catalyst poisons (such as sulfur, chlorine, arsenic, etc.). The following are the activity changes of TAP catalysts at different toxic concentrations:

Poison	Concentration (ppm)	Activity retention rate (%)
Sulphur	100	95
Chlorine	50	90
Arsenic	10	85

Practical Application Cases

1. Petroleum refining

In the petroleum refining process, TAP catalysts are widely used in key steps such as catalytic cracking and hydrotreatment. Its high temperature stability and anti-toxic properties ensure high efficiency and stability of the oil refining process.

2. Chemical Production

In chemical production, TAP catalyst is used to produce important chemical products such as synthesis of ammonia, methanol, and ethylene. Its high conversion rate and selectivity significantly improves production efficiency and product quality.

3. Environmental Protection

In the field of environmental protection, TAP catalysts are used in automobile exhaust treatment, industrial exhaust purification, etc. Its corrosion resistance and high temperature stability allow it to maintain efficient catalytic performance in harsh environments.

Conclusion
