Abstract:
     The invention provides a novel ferro-base low-chromium sulfur-resistant high temp. transformation catalyst. The mfg. method is simple and convenient. Owing to the multiple auxiliary agents, the content of chromium auxiliary can be reduced to 2.8% (wt.). The present invention develops a new technology for stepped co-precipitation method and optimizes the auxiliary components and technological conditions, thus improving the sulfur-resistance of the catalyst, widening the operating temp. range, and increasing the mechanical strength.
