生物质基微纳米助燃剂的制备及其在火驱化学点火中的可行性
Preparation of a biomass-based micro-nano combustion agent and its feasibility of chemical ignition in fireflooding
摘要
Abstract
In chemical ignition for heavy oil fireflooding,chemical combustion agents are required.To address the high storage-transport risk and high cost of existing chem-ical agents,a biomass pulp was used as raw material to prepare a biomass-based micro-nano chemical combustion agent(DES-US-BIO)via a deep eutectic solvent-ultra-sonic method.The structure of DES-US-BIO was characterized in terms of average particle size and crystallinity.Combustion cell experiments were carried out,including measurement of activation energy and analysis of combustion characteristics,and the combustion-promoting performance of DES-US-BIO was evaluated.The results show that the prepared material has an average particle size of about 628 nm and an ignition temperature of 240.0-260.0℃.The activation energy in the combustion stage ranges between 69×103 and 160×103 J/mol.DES-US-BIO can accelerate crude oil ignition and promote temperature increase at the combustion front,thereby improving the oil re-covery efficiency.The micro-nano size and low ignition temperature of DES-US-BIO meet injection requirements and can provide initial ignition energy as well as increase fuel concentration,endowing it with great application potential for chemical ignition in fireflooding development.关键词
