Abstract
A method of recovering a hydrocarbon from a reservoir, whereby an oil recovery formulation containing carboxylic acid functionalized-pyrolyzed date leaf particles is injected into the reservoir, and the hydrocarbon is collected from the reservoir. The carboxylic acid functionalized-pyrolyzed date leaf particles are obtained sequentially from date leaves by cutting the date leaves and drying, pulverizing in the presence of a metal bicarbonate, pyrolyzing at 700 to 1,000° C., and treating the product thus obtained with an acid solution that includes nitric acid to introduce carboxylic acid functional groups.
