Abstract
A process is presented for the removal of contaminants like sulfur compounds from hydrocarbons. The sulfur compounds are removed from hydrocarbons that may be a feed to cracking units. A feed stream is treated with a clinoptilolite or a barium exchanged zeolite adsorbent to effectively remove carbon disulfides from the feed hydrocarbon. The adsorbent may be regenerated by a hydrogen stream, a hydrocarbon stream or a mixture thereof.
