Precursor of iron catalyst for synthesis of ammonia, with the structure of wustite and method for obtaining of the precursor of iron catalyst with the structure of wustite, for synthesis of ammonia

摘要

catalyst precursor containing ferric chloride, in the form of phase wustytowu0105 and oxides promoters is characterized by the fact that contains cobalt oxide (ii) in quantities of from 2 to 5 weight%. the precursor contains oxides promoters in quantities of al2o3 from 2,2% by weight. to 4,5% w / w, cao from 1.7 wt%. to 2.8% by weight. and k2o from 0.4 wt%. to 0.9 wt%.process to obtain a catalyst precursor ferro cobalt on structure of wustytu ammonia synthesis of iron oxides in the presence of a reducing agent to the drowning, promoters, chilling and fragmenting the cast, characterised by the fact that during melting, the cobalt oxide (ii ) in quantities of from 2 to 5 weight%.a pressure regulator is used waste ferric catalyst ammonia synthesis in a quantity of from 15 to 30% relative to iron oxides. as promoters used al2o3 in quantities from 2,2% to 4.5% by weight, cao in quantities from 1.7% to 2.8% by weight and kno3 in quantities of from 0.4% to 0.9% by weight.
