example

[0031] For an easier understanding of the embodiments, reference is made to the following examples, which are intended to illustrate the embodiments disclosed and described in this application. These examples in no way limit the scope.

[0032] Carbon black was pretreated with the following procedure: obtained from Denka and having a particle size of 35nm, 68m 2 Acetylene black with a surface area of ​​ / g and an ash content of 0.01 weight percent was soaked in nitric acid (2 standard values ​​(N)) for 24 hours at room temperature. Then, filter the carbon black and blow it with flowing nitrogen (N 2 ) was dried at 250°C. The dried carbon black was added to deionized water (having a conductivity of less than 0.056 microSiemens per centimeter (μS / cm); Type I water by ASTM definition) and refluxed for at least 6 hours before adding the magnesium compound. The weight ratio of carbon to water after drying is 1:2. The mixture of carbon and water, called carbon black slurry (CBS),...

Abstract

The present embodiments describe a method to reduce vanadium corrosion in a gas turbine by adding an oleophilic corrosion inhibitor into a combustion fuel, in which the oleophilic corrosion inhibitorcomprises carbon black support particles and magnesium bonded to the carbon black support particles. The carbon black support particles comprise a particle size less than 40 nanometer (nm), and oxygencontent less than 1 weight percent (wt%), and a surface area of at least 50 square meters per gram (m2 / gram).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 62 / 324,387, filed April 19, 2016, which is hereby incorporated by reference in its entirety. technical field [0003] Embodiments of the present disclosure relate generally to combustion fuel additives, particularly vanadium corrosion inhibitors in gas turbines. Background technique [0004] One of the most common methods of generating energy is the combustion of hydrocarbons, including natural gas, petroleum gas, coal, and liquid hydrocarbons such as petroleum crude oil. Combustion produces heat, steam, electricity and other types of energy. Gas turbines and internal combustion engines are representative machines that use hydrocarbons to generate energy. A gas turbine has two main components: the combustor and the rotating turbine. Energy is produced from the combustion of hydrocarbons, and the efficiency is strongly dependent on the i...
