Zusammenfassung:The invention relates to a biomass tar reforming catalyst and a preparation method thereof. The preparation method comprises the following steps of: 1) drying, grinding and screening steel slag to obtain a steel slag raw material for activation; 2) adding a nitric acid solution into the steel slag raw material, stirring for a reaction, and performing drying to obtain a nitric acid activated catalyst steel slag carrier; (3) putting the carrier prepared in the step (2) into a nickel nitrate solution, dipping the carrier, and then adding a nano silica sol solution to shape the carrier so as to prepare spherical particles with the particle size of 3-5mm; and 4) drying the catalyst particles prepared in the step 3), calcining the catalyst particles, and carrying out hydrogen reduction to prepare the activated nickel-based steel slag catalyst. Compared with the prior art, the preparation method has the advantages of low cost, environment friendliness and high resource utilization degree; and the prepared activated
