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

One oil family contains relatively low amounts of C\-\{15\}\|C\-\{20\} isoprenoid hydrocarbons and shows pristane predominance with Pr/Ph ratios ranging from \{1.50\} to \{3.00\}. The GC/MS analytical data of these oils show the occurrence of abundant hopanes, and low concentrations of steranes and tricyclic terpanes with hopanes/steranes ratios from \{6.25\} to \{12.24\} and tricyclic terpanes/hopanes ratios from \{0.03\} to \{0.24\}. These oils contain low drimane relative to homodrimane (C\-\{15\}/C\-\{16\}<1.0) and abundant rearranged bicyclanes in bicyclic sesquiterpanes. They are dominated by low carbon number (C\-\{19\}\|C\-\{21\}) compounds in the tricyclic terpanes, and are rich in rearranged hopanes, C\-\{29\}Ts and an unknown C\-\{30\} compound in pentacyclic triterpanes. These geochemical characteristics suggest that the oils were generated mainly from terrigenous organic matter. The other oil family shows remarkably different biomarker compositions and distributions. The oils revealed Pr/Ph ratios of about \{1.0\}, high drimane/homodrimane ratios (>\{1.0\}), low hopanes/steranes ratios (\{0.65\}-\{2.50\}), high tricyclic terpanes/hopanes ratios (\{0.30\}-\{2.00\}) and a dominant peak at C\-\{23\} in tricyclic tepanes, suggesting a marine organic origin. Oil\|source rock correlation indicates that these two oil families seem to have been derived from Mesozoic Jurassic\|Triassic terrestrial source rocks (shales and coal seams) and Lower Paleozoic Ordovician\|Cambrian marine source rocks, respectively.展开更多

The FH-DS type catalyst has excellent HDS and HDN activity thanks to modification of alumina through incorporating additives, optimization of catalyst preparation and optimal combination of active ingredients.Under low pressure the HDS activity of this catalyst is by 50% higher than that of domestic reference catalysts available in the market and is slightly better than that of foreign reference catalyst. When this catalyst is used for manufacture of clean ultra-low sulfur diesel (containing <30 ppm of S), its volumetric relative desulfurization activity is 46% higher than that of foreign reference catalyst, and this catalyst is an excellent catalyst for manufacture of low-sulfur clean diesel fuel derived from imported high-sulfur Kuwaiti and Arabian crude oils.展开更多
