Problems solved by technology

[0004]At present, heavy oil usually needs to be reduced in viscosity before being transported, but there are still many problems in the existing means of viscosity reduction, such as heating for viscosity reduction transportation, and there is a need to add intermediate heating station, heat energy loss, and high cost; mixed transportation viscosity reduction is only suitable for specific occasions, and sufficient light diluent oil is required; emulsification viscosity reduction still has many problems in terms of emulsion rheology, pipeline design, and emulsion dehydration. ; Modification and viscosity reduction technology requires new refinery units, such as thermal cracking, hydrocracking, coking and other large investment

Abstract

The invention provides a heavy oil curing agent, a preparation method thereof and a modified heavy oil composition. The heavy oil curing agent comprises resin, a wax substance, a curing agent and a cross-linking agent. The heavy oil curing agent is obtained by uniformly mixing the components according to the proportion. The invention also provides a modified heavy oil composition. The modified heavy oil composition comprises heavy oil, resin, a wax substance, a curing agent and a cross-linking agent. The modified heavy oil composition obtained by the method disclosed by the invention can be made into solid-phase particles after being treated, so that the solid-phase particles are convenient to transport, and after being transported to a destination, the modified heavy oil composition can be recovered to a state capable of being subjected to subsequent processing only by heating treatment, and no adverse effect is generated on the properties of heavy oil; and through the use of the curing agent, the viscosity of the material can be adjusted after the subsequent temperature rise, which is beneficial to the subsequent hydrotreatment of the heavy oil raw material.

Description

technical field [0001] The invention belongs to the field of petrochemical industry, in particular to a heavy heavy oil solidification technology based on kerosene co-refining route, so as to facilitate long-distance transportation. Background technique [0002] Compared with the price of conventional crude oil in the current crude oil market, super-heavy heavy oil has the advantage of low price. However, it does not flow at room temperature and is difficult to transport and store by conventional methods. Shipping requirements. At present, the world's proven heavy oil reserves account for 70% of the world's remaining oil reserves; they are mainly distributed in the Orinoco heavy oil belt in Venezuela, the Western Canada Basin in Canada, and the East Siberian Basin in Russia. At present, the main treatment method is to add diluent oil or emulsification method to reduce the viscosity. Adding diluent oil has very limited sources of diluent oil in heavy oil production areas, an...
