Abstract
A process and apparatus are provided for reducing content of tar in a tar containing syngas. The process includes contacting the tar containing syngas with a molecular oxygen containing gas in a first reaction zone to produce a gas mixture. The gas mixture is passed through a heat treatment zone maintained at a temperature between about 900° C. to about 2000° C. for a contact time of about 0.5 to about 5 seconds. In this aspect, at least a portion of the tar undergoes at least partial oxidation and/or cracking to produce a hot syngas.
