Precautions for storage, transportation and use
I. Pay attention to waterproof and moisture-proof, and prohibit contact with other chemicals and hydrocarbon substances.
II. Do not drop or roll the iron bucket during handling.
III. The product is delivered in the reduced state. The loading of catalyst should be carried out in sunny days, and the contact time between catalyst and air should be shortened as much as possible. After loading, the reactor should be sealed in time and filled with nitrogen for protection.
Ⅳ. The start-up shall be carried out in strict accordance with the catalyst start-up manual provided by Shandong Green Star Catalytic Technology Co., Ltd., and under the guidance of professional technicians when necessary.
