Based on this technology, Maoming Petrochemical Company constructed the hydrotreating unit with a capacity of 2 Mt/a to treat high sulfur residue, in which loaded FZC series catalysts were developed by FRIPP. The unit was first put into commercial operation at the end of 1999. The commercial operation showed that the catalysts have good activities and the products meet the designed specifications.展开更多

This article has discussed the technol- ogy for processing of different resids and the advantages and disadvantages of the combination pro- cesses for resid processing, while pinpointing the directions for development and application of tech- nologies for resid processing in China.展开更多

The conversion of whole resid into light oil is not economic at the normal price gap between the light and heavy oils. Hence a combination of hydrogenation process with carbon removal process is generally adopted.The heavy solvent deasphalting can selectively remove the asphaltenes and metals contained in resid while providing a large amount of easily convertible deasphalted oil for the down-stream processes.This article refers to the characteristics of heavy solvent deasphalting and its application in sour resid processing, along with various routes for utilization of deoiled asphalt.展开更多
