ABSTRACT:
In this combination process, solvent deasphalting (SDA) concentrates metals in the bottoms product which can be blended to asphalt as a product or for sending to the Calderon or similar process and outputs a high carbon (4+ concarbon) feed which is readily cracked to valuable transportation fuels by an RCC.RTM. cracking unit (or a conventional FCC with catalyst cooler and oxygen to the regenerator so that it acts as an RCC). The Rose process can be used instead of SDA to save utilities. By this invention, heavy crude can be converted to valuable transportation fuels and asphalt product, and catalyst make-up can be sharply reduced in the RCC or FCC unit because metals (asphalteries and porphyrins) are removed before cracking. Novel asphalt compositions and blending are also disclosed. Asphalt from the SDA can preferably be blended with lube plant extract (or other aromatic extract) to produce specific asphalts meeting new SHRP specifications for paving.
