Reliable Ammonia Catalyst Solution
Pre-Reforming Catalyst with Excellent Low-Temperature Activity
YZ119/YZ119R Pre-Reforming Catalysts for Refinery Feed Applications
SYAMCAT YZ119 and YZ119R are nickel-based pre-reforming catalysts. This page presents the grades within our refinery product range, with a focus on evaluating hydrocarbon feeds such as refinery off-gas for a pre-reforming stage.
For refinery feed applications, please identify the hydrocarbon composition, variations in the feed and upstream treatment. Catalyst suitability should be reviewed against the actual feed and reactor conditions.

Selection and Loading Considerations
Feed and Process Route
For refinery feed applications, please identify the hydrocarbon composition, variations in the feed and upstream treatment. Catalyst suitability should be reviewed against the actual feed and reactor conditions.
Oxidized or Pre-Reduced Grade
Confirm whether the oxidized or pre-reduced grade is required and review the applicable activation and startup instructions.
Reactor and Loading
Provide pre-reformer dimensions, feed rate, operating conditions and current catalyst loading for grade evaluation.
Discuss Your Refinery Feed Applications Requirements
Please share your feed composition, operating temperature and pressure, steam-to-carbon ratio, reactor dimensions and current catalyst information. Include your process application and whether an oxidized or pre-reduced grade is required.
