Problems solved by technology

With the increase in the amount of heavy oil and the gradual shortage of oil, saving petroleum products and improving their application efficiency has become one of the country's important energy-saving content, and a certain amount of petroleum coke powder and water are added to fuel heavy oil to form coke-oil - The new water fuel system has significant economic and social benefits of energy saving and environmental protection. The technical key to formulating this new fuel system is to be able to disperse the three immiscible components evenly, so that it can be pumped and sprayed when applied. And atomization requirements, currently there is no suitable rheology agent with good dispersion, stability, drag reduction (viscosity reduction) function

Abstract

The invention discloses a multifunctional compound rheological agent and a preparation method thereof, which relate to a rheological agent prepared by unsaturated monomers such as acrylamide and the like through copolyreaction and the preparation method thereof. The compound rheological agent is a composition which is prepared from the products which serve as main components and are obtained by performing the copolyreaction on acrylamide, acrylic acid, styrene sulfonic sodium and maleic anhydride in a certain ratio through an initiating system of oxidation-reduction, and a dispersant and an emulsifier which serve as auxiliaries. The composition is used in used for fuel pulp slurry of petroleum coke powder, heavy oil and water, and has the functions of dispersing and stabilizing a system, and can fulfill the aims of pumpability, spraying capability, atomization, energy conservation and environment protection under use conditions.

Description

technical field [0001] The invention relates to a rheological agent prepared by copolymerization of unsaturated monomers such as acrylamide and its compound preparation method with dispersed and emulsified components, and is mainly used for the preparation of petroleum coke powder-heavy oil-water new fuel system . Background technique [0002] Petroleum is one of the important one-time energy materials. As the heavy oil in petroleum components, it is an important boiler fuel for metallurgy, glass, power generation and other industries. With the increase in the amount of heavy oil and the gradual shortage of oil, saving petroleum products and improving their application efficiency has become one of the country's important energy-saving content, and a certain amount of petroleum coke powder and water are added to fuel heavy oil to form coke-oil - The new water fuel system has significant economic and social benefits of energy saving and environmental protection. The technical...
