Reliable Ammonia Catalyst Solution
Hydrogenation Catalyst with Stable Structure for Purification Process
YJ17/YJ18/YJ19 Hydrogenation Catalysts — Ammonia Plant Feed Review
SYAMCAT YJ17, YJ18 and YJ19 are hydrogenation catalyst grades with cobalt, molybdenum and nickel active components. This page presents the grades within the ammonia plant feed purification range.
For an ammonia plant enquiry, please describe the actual feed gas, hydrogen availability, organic sulfur and olefin content, reactor configuration and downstream purification requirements. Review grade suitability against the specific process.

Selection and Loading Considerations
Feed Hydrogenation
Review organic sulfur conversion and olefin saturation requirements against the actual feed and available hydrogen.
Reactor Configuration
Provide reactor dimensions, bed arrangement and current catalyst loading so that grade selection can be reviewed.
Startup and Operating Instructions
Confirm the current grade-specific technical data sheet and startup procedure before setting operating conditions.
Discuss Your Ammonia Plants Requirements
Please share the feed composition, sulfur species and concentrations, olefin content where applicable, gas flow, operating conditions, vessel dimensions, current catalyst or sorbent loading and the required outlet specification.
