Product Introduction
I. LSH-800 series catalyst is a Pd/AI2O3 type 2-ethylanthraquinone
hydrogenation catalyst with high hydrogenation activity and high
selectivity developed by Shandong Green Star Catalytic Technology
Co., Ltd.
II. LSH-800 catalyst is an economical catalyst with low palladium
content.
Ⅲ. The product appearance is φ 2.2~2.5mm gray black ball.
Product characteristics
The catalyst uses new catalytic materials with high mechanical
strength, high hydrogenation activity and selectivity, and long
service life, which greatly increases the economy of catalyst use.

Product packaging
The special iron drum is sealed and packed, and the inner layer is
covered with a cloth bag and a plastic bag, with a net weight of
100kg/barrel, and filled with nitrogen for positive pressure
protection.
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.
