Abstract

The invention discloses a catalytic oil slurry modifier. The catalytic oil slurry modifier is mainly used to modify a catalytic oil slurry through an end blocking reaction in order to improve the heat stability and the oxygen stability of the catalytic oil slurry, so soft components needed by deoiled asphalt blending for producing high-grade road asphalt are obtained. The modifier comprises, by weight, 94-99% of an aldehyde compound, 0.5-3% of a catalyst and 0.5-3% of an alcohol compound. A modified oil slurry obtained in the invention has the advantages of low price, low viscosity, and high stability to heat and oxygen, and can meet GB15180-2010 requirements of high-grade road asphalt after being blended with the deoiled asphalt.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and mainly relates to a modifier for catalytic oil slurry, in particular to a modifier for improving the anti-aging performance of catalytic oil slurry by utilizing end group sealing technology. Background technique [0002] The solvent deasphalting process can selectively remove heavy metals, colloids and asphaltene rich in residual oil, and provide deasphalted oil with good performance for downstream processes. Solvent deasphalting process not only obtains deasphalted oil with low metal and carbon residue, but also by-produces a part of deoiled asphalt with low oil content, high softening point, high heavy metal content, low penetration and low added value. The solvents used in the solvent deasphalting process mainly include C 3 、C 4 and C 5 , the larger the molecular weight, the higher the softening point of deoiled asphalt, but the more difficult it is to use. The potential...
