And the catalytic activities of hco 红外光谱及羰基钴氢催化活性的理论研究
Theoretical studies on the ir spectra of co2 8 and the catalytic activities of hco 3 and hco 4 Co2 co 8红外光谱及羰基钴氢催化活性的理论研究
Based on the research progress in iron untrition of plant , the mechanism of iron uptake and transport by plant and the effect of hco ( superscript - subscript 3 ) , n , p on iron use efficiency were discussed 摘要根据植物铁营养的一些研究进展,论述了植物对铁的吸收和运输机理以及hco (上标-下标3 ) 、 n 、 p等因素对铁利用效率的影响。
Various feedstocks such as straight run distillate ( tbp in the range of 250 to 400 ) , hco from fcc and the unconverted oil of hydrocracking can be processed to reduce the pour points for increasing diesel fuel production , accompanied with a higher overall gasoline plus diesel fuel yield in refinery 以直馏轻蜡油、催化裂化重柴油和加氢裂化尾油为原料,经降凝可大幅度增产柴油,并可提高炼油厂轻质油收率、提高柴汽比、满足市场需求。
