| The current research directions in the catalyses for heavy oils up-grading are reviewed from five aspects in the production and refining of heavy oils. 1. Enhanced Recovery of Heavy End in Crude; 2. Primary Removal of Minerals, Salts, and Metals in the Heavy End; 3. Primary Hydrogenation, Hydrodesulfurization, Hydrodenitrogenation and Hydrodeoxygenation prior to the Cracking; 4. Cracking and Hydrocracking for Distillate Production; 5. Deep Refining of Distillate Products from the Heavy End. In these steps, roles the catalysts and adsorbents are emphasized by the assistance of solvent and/or solvent-like components. The processes must be also adequately designed for the catalysts and adsorbents to play the optimum roles against the well defined target species in the respective feeds. The catalyst and adsorbent can be designed by clarifying the objected catalyses and issues accompanied with the substrates, establishing the stricture / performance correlation and modelling the structure of the catalysts and adsorbent. Multi-components as distributed according to their roles can be included in the catalyst and adsorbent for respective objectives. |
