Abstract

The invention belongs to the technical field of gas hydrate production promotion and utilization, and in particular relates to a hydrate accelerator and a preparation method thereof. said Hydration Promoter, It is prepared by stirring cocamidopropyl betaine, dimethylsiloxane, non-ionic fluorosurfactant and deionized water at 65~85℃ for 30~40 minutes; among them, cocamidopropyl The mass percentage of betaine in the solvent is 3-7%; the mass percentage of dimethylsiloxane in the solvent is 1.2-4.5%; the mass percentage of non-ionic fluorosurfactant in the solvent is 0.2- 1.5%, and the rest is deionized water. The hydrate accelerator of the present invention can be widely used in the fields of gas hydrate storage and transportation technology, gas hydrate separation technology, and seawater desalination; and the cost is low, the dosage is small, the conditions for hydrate formation are reduced, the time is shortened, and the gas storage capacity is reduced. The increase effectively improves the economic benefits of hydrate production.

Description

technical field [0001] The invention relates to the technical field of gas hydrate production promotion and utilization, in particular to a preparation method of a composite accelerator for accelerating the formation of gas hydrate. Background technique [0002] Gas hydrate technology involves a wide range of fields. It not only develops rapidly in the fields of energy and environmental protection, but also has made significant progress in other fields, such as solid-state transportation and storage of natural gas, natural gas hydrate as vehicle fuel, and gas hydrate based on the formation of hydrate. New separation technologies (seawater desalination technology, concentration of organic aqueous solution, separation of gas mixtures and near-critical and supercritical extraction, etc.), as well as the fields of hydrate bioengineering and new materials, etc. However, the gas hydrate technology is affected by factors such as harsh formation conditions, long induction time, slow...
