| A new type of hydrothermal aging device rotation of FCC catalyst evaluation
Cup stacking multiple samples is greater than the height of the higher accuracy of temperature control; and aging of the device samples the level of rotation is horizontal, without a long length of constant temperature, temperature control system is easy to meet the requirements. (4 ) the traditional aging process of aging equipment in the waste gas generated in the collection system is not set, it does not meet the HSE management system requirements; and horizontal rotation set up a special addition to the aging plant powder cans, reducing environmental pollution. (5) the aging of the traditional device aging, up to 4 samples; and a horizontal rotating device may be aging aging 6 to 12 samples, greatly improving the efficiency of research and analysis. (6) new rotary device in automatic control of aging , aging water flow control and measurement,ugg botas, aging air ratio control and measurement, data storage and so much better than the aging of the device. 6 Conclusion (1) hydrothermal aging device is a new type of rotating device aging, one can handle 6 to 12 samples, 8 samples of the same age, the aging of the parallel activity of the catalyst after the error is less than ± 1, repeat good, the experimental efficiency. (2) rotating the aging device for powder, microspheres, particles of different shapes such as the catalyst of the water treatment. Anti-aging and micro-rotation with the activity evaluation, evaluation of cracking catalyst can improve the efficiency and accuracy. References [1] Chen Junwu. FCC Technology and Engineering [M].
