Abstract

The invention relates to a high-efficiency oil slurry settling agent, belonging to the technical field of settling agents. According to the invention, brewer's grains are subjected to pulverization, nitrification, mixing with triethyl citrate and other treatment to obtain a component with a high film-forming property and a unique chelate structure, and the component is adsorbed onto the surfaces of particles through formation of hydrogen bonds by a part of ionic groups and the particles and plays a bridging role among the particles so as to allow settled flocs to be generated and settling effect to be improved; active resin is produced from tert-butylphenol and tetraethylenepentamine, and is used as an initiator for anionic ring-opening polymerization with epoxypropane so as to produce polyether substances, so an interfacial film is allowed to become loose, the strength of a droplet interface film is weakened or destroyed, and the stability of an emulsion is destroyed, thereby achieving the effects of coalescence, flocculation and sedimentation. The high-efficiency oil slurry settling agent of the invention solves the problem of poor sedimentation effect of commonly-used oil slurrysettling agent at present.

Description

technical field [0001] The invention relates to the technical field of sedimentation agents, in particular to a high-efficiency oil slurry sedimentation agent. Background technique [0002] Catalytic cracking oil slurry (FCC oil slurry) is unconverted hydrocarbons with a distillation range of 343°C to 593°C thrown out from the bottom of the FCC fractionation tower. It is rich in colloids and asphaltene, and has the characteristics of high viscosity and high density. Currently, FCC slurries are generally handled as inexpensive heavy fuel oil. The oil slurry contains 30% to 50% saturated hydrocarbons, which are high-quality raw materials for catalytic cracking; at the same time, the aromatics in the oil slurry reach more than 50%, and further processing of polycyclic aromatics can produce carbon fiber materials, needle-shaped High value-added products such as coke and carbon black have a wide range of uses and broad market prospects. However, because FCC oil slurry contains ...
