Problems solved by technology

[0002] At present, diesel oil is widely used as a fuel in passenger cars, trucks, large excavators, loading machinery, boilers and other fields. With the continuous increase of oil consumption, crude oil resources have been overexploited, and oil resources are becoming less and less , all countries in the world will face the problem of energy shortage and shortage, which will make the price of oil continue to rise, and the existing diesel oil cannot be completely combusted, with many pollutant emissions and high sulfur content. In order to ensure the low-carbon combustion emissions of

Example Embodiment

[0016] Example one

[0017] One kind of lower diesel methanol, methanol diesel feedstock prepared: 15 parts of vegetable oil acid, 20 parts methanol, 10 parts of cetane number improvers, 4 parts of isobutanol, 3 parts of n-butanol, and 3 parts of a catalytic additive 45 parts of the base diesel.

[0018] Specific steps diesel methanol production process is:

[0019] S1: at normal temperature and pressure conditions, according to the parts by weight of diesel weighed added to the reaction kettle, followed by addition of an appropriate amount of parts by weight of methanol and vegetable oil acid with stirring, to obtain a mixed material;

[0020] S2: parts by weight were weighed in accordance with n-butanol and isobutanol, is added to the mix obtained in step S1, and then the mixing kettle was heated to 80 ° with stirring, stirred for 40 minutes, to facilitate material sufficiently dissolved, then cooled to room temperature, to obtain a modified diesel methanol, and methanol-modifie...

Abstract

The invention discloses low-carbon methanol diesel oil and a preparation method thereof. The low-carbon methanol diesel oil is prepared from vegetable oleic acid, methanol, a cetane number improver, isobutanol, n-butanol, a catalytic additive and base diesel oil, a traditional methanol diesel oil preparation method is changed, and substances added into the diesel oil can be better dissolved and combined. The problems that existing diesel oil is large in viscosity, prone to freezing, poor in fluidity and difficult to start at the low temperature at the low temperature are solved, the low-temperature fluidity is high, meanwhile, the combustion performance is not reduced, the content of CO and hydrocarbon in tail gas emission when a vehicle combusts the diesel oil is remarkably reduced, black smoke in the tail gas emission is eliminated, pollution to the atmosphere is greatly reduced, the effects of low carbon and environment friendliness are achieved, methanol diesel oil is easy to store for a long time, ignition startability is good, lubricity can be improved, and rod end abrasion and boundary abrasion of an air inlet valve and an air outlet valve of a piston ring of an engine are reduced.

Description

technical field [0001] The invention relates to the technical field of low-carbon methanol diesel, in particular to a low-carbon methanol diesel and a preparation method thereof. Background technique [0002] At present, diesel oil is widely used as a fuel in passenger cars, trucks, large excavators, loading machinery, boilers and other fields. With the continuous increase of oil consumption, crude oil resources have been overexploited, and oil resources are becoming less and less , all countries in the world will face the problem of energy shortage and shortage, which will make the price of oil continue to rise, and the existing diesel oil cannot be completely combusted, with many pollutant emissions and high sulfur content. In order to ensure the low-carbon combustion emissions of diesel oil to obtain low-carbon diesel fuel, blending methanol with diesel oil is one of the effective means. Currently, methanol is prepared by blending methanol in the market There are many wa...
