Product Description

1. Product features and scope of application

zinc oxide adsorbent HTZM-1 is applicable to deep desulfurization of liquid propylene and industrial feed gases at ambient temperature. It not only absorbs hydrogen sulfide, but also has certain conversion and absorption capability for COS in the stream.Overall sulfur(H2S+COS)in the treated stream can be less than 0.1ppm.

2. Physical properties

3. Quality normal

4 . Operation condition

No regeneration is needed for spent adsorbent. But absorption may continue after the adsorbent bed is broken through , until the catalyst is finally saturated with sulfur. For example, feed stream can pass through 1st reactor even when it has been broken through, until it is saturated with sulfur and changed. This lowers sulfur content in the stream to 2nd reactor and makes full play of the absorption capacity of the adsorbent in 1st reactor.

5 .Loading

(1).Clean the reactor of any debris and screen out any dust from the adsorbent.
(2).Install two layers of stainless wire net of smaller mesh size than the adsorbent and then 100mm depth of Φ20-30mm inert balls on grid of the reactor. And again install two layers of stainless wire net of smaller mesh size than the adsorbent on top of the inert balls.
(3).Use special tools to load the adsorbent evenly into the reactor. Inspect uniformity of the loading. When inner-reactor operation is needed, lay a plate on the adsorbent first for the operator to step upon.
(4).Install a layer of stainless wire net of smaller mesh size than the adsorbent and 100 depth ofΦ20-30mm inert balls on top of the bed to prevent stripping of the adsorbent by process stream and ensure uniform distribution of process flow.
6.Start-up and shutdown
(1)Close all inlet and outlet valves before start-up. Then open liquid propylene inlet valve and raise pressure at 0.5MPa/ 10 min.
(2)Open the outlet valve slowly after reactor pressure approaches that of that feed. Run at a quarter load for four hours and analyze outlet sulfur to ensure an outlet sulfur concentration of no greater than 0.1 ppm.
(3)Enhance to half load when outlet sulfur concentration is up to the process requirement and transit to full load operation in several hours.
(4)Close inlet valve first and then close outlet valve to disconnect the reactor from system before shutdown.
(5)Avoid wide scope fluctuation in pressure and load, which may impair the adsorbent.
(6)For gaseous feed desulfurization system, purge the system with inert gas (e.g., nitrogen) before start-up or after shutdown. For the rest of procedure, please refer to procedure for Liquid Propylene Desulfurization Adsorbent HTZM-1.
7. Transportation and storage
(1) The adsorbent is packed in plastic or iron barrels lined inside with plastic bags to avoid moisture or chemical attack.
(2) Avoid tumbling, collision and vibration.

Company Information

Founded in Shanghai in 2019, Shanghai Jisi Environmental Protection Technology Co., Ltd. is a technology, sales and service company focusing on the environmental protection of industrial exhaust gas; In the same period, a brand new catalyst brand "Hive Tech" was created for the industrial exhaust catalyst market, aiming to provide high-quality catalysts for the market.

The establishment of "Haifu" hopes to make domestic brands occupy a place in this market through continuous R&D investment and its advanced production equipment. Our fully automated production line brings fast response and delivery as well as high quality and stability. Localized production brings high cost performance products, thus breaking the monopoly and leading position of imported catalysts.

The company's main products are precious metal/base metal catalysts for VOC emission reduction, SCR catalysts. In addition to general-purpose catalysts, the company also launched efficient alkane catalysts, S-resistant catalysts and halogen resistant catalysts for various market segments.

In addition, the shareholders and relevant beneficiaries of the Company also act as agents for other environmental protection related products, such as pumps/valves/control components, to obtain the best price through long-term cooperation with suppliers of this type for foreign trade business.
