Product Description

Our company successfully developed the high-boiling matter cracking process in 2015. The first 5,000-ton/year unit was commissioned in 2019, producing qualified trichlorosilane and silicon tetrachloride products. The actual operation of the unit demonstrates that our company's process and equipment possess the following numerous advantages:

(1) Capable of processing feedstocks with extremely high impurity content from cold hydrogenation, with the final product meeting the requirements for polysilicon production.

(2) Near 100% single-pass conversion rate of hydrogen chloride, which is industry-leading.

(3) Near 100% conversion rate of crackable high-boiling matter, which is industry-leading.

(4) Catalyst consumption as low as 0.3 kg per ton of high-boiling matter, which is industry-leading.

(5) Achieves complete recycling of spent catalyst; COD and ammonia nitrogen in wastewater meet discharge standards, with no odor.

(6) Metal chlorides, phosphorus, and boron in the cracking products comply with the quality specifications of chlorosilan
