LF701 Ammonia Synthesis Catalyst

 

1 Introduction

  LF701 is a kind of ammonia synthesis catalyst with high activity, operating at low temperature and low pressure. It has good reducibility, easy to reduce at low temperature, high heat resistance and poisoning resistance, strong suitability to inert gases and H/N ratio fluctuation, not only suited to low pressure synthesis but also suited to medium and high pressure synthesis. Its performances have reached or exceeded the advanced world level of the catalysts of the same kind.
