Abstract

The present invention belongs to the technical field of organic chemical industry, and relates to a heavy oil viscosity reducer and a preparation method thereof, the viscosity reducer is prepared by ternary polymerizationof fluorocarbon alcohol ether (methyl) acrylate, maleic anhydride and styrene, the preparation method comprises the following stesp: synthesis of fluorocarbon alcohol ether; synthesis of fluorocarbon alcohol ether acrylate, synthesis of a ternary polymer, and preparation of the viscosity reducer. The advantages are as follows: the viscosity reducer can significantly reduce the viscosity of a variety of heavy oil especially cycloalkyl heavy oil, can prevent wax from forming a network structure, also can make asphaltene and colloid highly dispersed. The viscosity reducer can make the colloid stabile in property, the heavy oil may not be layered by placing for long time, and the viscosity reducer is remarkable in viscosity reduction effect, low in cost, and facilitates oil transport and application.

Description

Technical field [0001] The invention belongs to the technical field of organic chemicals, and relates to the preparation and application of a thick oil and ultra-heavy oil viscosity reducer, and in particular to a thick oil viscosity reducer and a preparation method thereof. Background technique [0002] Heavy oil has the outstanding characteristics of high viscosity, high density and high freezing point, which severely restrict its industrial application. For the utilization of high-viscosity and high-pour oil products, traditional methods mainly adopt heating and emulsification to reduce viscosity. The former requires a large amount of fuel and power; the latter, although the viscosity reduction effect is significant, has a large amount of water ( Usually up to 30wt%), the later dehydration treatment is difficult and the process is complicated. The use of chemical additives to reduce the freezing point and viscosity of oil products has attracted more and more attention from th...
