[Problem] To provide a fuel oil composition that can impart excellent lubricity to low-sulfur diesel fuel oil. [Solution] A fuel oil composition comprising an ester reaction product (A) that satisfies all of the following (1) to (3), and diesel fuel oil (B), wherein the sulfur content in the diesel fuel oil (B) is 0.1% by weight or less. (1) It is an ester reaction product of a fatty acid (a) having 12 to 26 carbon atoms and sorbitan. (2) The ratio of ester condensates based on the weight of the ester reaction product (A) is 0.1 to 50.0% by weight. (3) The hydroxyl value of the ester reaction product (A) is 150 to 400 mgKOH/g.

The use of a nitrogen containing detergent as an additive in a diesel fuel composition to reduce the impact of deposits in an EGR system of a diesel engine when combusting said diesel fuel composition.

A method for regulating and controlling a generated crystal form of a natural gas hydrate is provided. A mixture composed of a salt substance, a surfactant, a water-soluble thermodynamic additive and water is introduced in a generation process of the natural gas hydrate. The salt substance and the surfactant also have a synergistic effect with a water-soluble thermodynamic accelerator. The addition of the salt substance and the surfactant can change a local solubility of the water-soluble thermodynamic additive in water, so that the regulating and controlling process of the hydrate crystal can be realized, thereby improving a hydrate gas storage capacity and solving the problem of low natural gas storage capacity in the generated natural gas hydrate in a water-soluble thermodynamic additive system.

The present invention relates to an additive for fuels such as diesel fuel and fuel oil, used respectively for diesel engines and boilers of various types, comprising a metal oxidation catalyst, an organic nitrate and a dispersing agent in suitable ratios, capable of improving combustion efficiency in such a way as to reduce the formation of particulate matter and consumption.

To reformulate a new fuel oil blend. Used lube oil feedstock, which is received from collection storage intermediary facilitiesis re-refined to form multiple re-refined byproducts including light solvent, used fuel oil, light extract, and heavy extract. A used oil composite byproduct is formed by blending a portion of the light solvent, a portion of the used fuel oil and a portion of the light extract. A portion of the used oil composite byproduct as viscosity cutter stock is blended with refined fuel oil to reformulate a final refined fuel oil blend. The refined fuel oil to which the portion of the used oil composite byproduct is added includes heavier hydrocarbons than the used oil composite byproduct.

The present disclosure relates to an integrated plant for production of renewable hydrogen and biomethane, comprising a biomass gasification unit configured to convert organic feedstock into product gas; a methanation unit coupled to the biomass gasification unit to process product gas and produce biomethane; an electrolysis unit configured to produce renewable hydrogen from water using renewable energy sources with more energy efficiency conversion; a gas storage unit for the safe storage of biomethane and renewable hydrogen; and a control unit for optimizing energy usage, gas flow, and overall process efficiency, increasing the energy efficiency of gasification, by low and medium enthalpy energy recovery for pre-treatment biomass, wherein the biomethane and renewable hydrogen are combined in a fuel cell conversion unit to generate clean water as a by-product. The oxygen produced by electrolysis is supplied to the gasification unit, the thermal energy recovered from the internal process units is used to preheat the electrolysis feed water, and the water produced by the fuel cell conversion is recovered and reused for electrolysis, thus forming closed internal cycles of mass and energy flows. The integrated facility offers an efficient and flexible solution for the production and use of renewable hydrogen and biomethane.

In some examples, a method of generating a fuel blend includes flowing a lipid feedstock into a reaction vessel comprising a metal oxide catalyst on an oxide support. The metal oxide catalyst in the reaction vessel is used to catalytically convert the lipid feedstock into a mixture comprising an intermediate composition having at least 70% of its oxygen within ketone groups. Distillation is used to obtain a distillation cut of the mixture. Without any further catalytic processing of the distillation cut, the distillation cut is blended with a fuel to create a fuel blend.
