  • Method of recovering hydrocarbon from a reservoir using date leaf carbon nanoparticles
    Patent number: 11845894
    Abstract: A method of recovering a hydrocarbon from a reservoir is described. The method includes injecting an oil recovery formulation into the reservoir, and collecting the hydrocarbon from the reservoir. The oil recovery formulation includes date leaf particles selected from the group consisting of carboxylic acid functionalized date leaf particles and non-functionalized date leaf particles. The date leaf particles have an average particle size of 30 to 950 nanometers (nm). A method for preparing the carboxylic acid functionalized date leaf particles is also provided.

  • Oil recovery methods using carboxylated pyrolyzed date leaves
    Patent number: 10836952
    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.
