Embodiment 1

[0018] A kind of preparation method of novel fuel, comprises the following steps:

[0019] (1) Mix 30% monoglyceride, 20-45% Span, 20% sodium dodecylbenzenesulfonate, 3% sodium carboxymethylcellulose (CMC), and 2% xanthan gum to obtain an emulsifier;

[0020] (2) Dissolve 5 kg of emulsifier in 175 kg of recovered oil, stir at 30°C and 4500 rpm, and emulsify for 30 minutes;

[0021] (3)然后在乳化液中加入煤粉含量占60%的水煤浆320公斤,搅拌转速为4500rpmrpm,搅拌时间为30min,混合均匀即得。

[0022] After testing, the finished product indicators are shown in the table below:

[0023] oily Moisture Ash Volatile matter Total sulfur low calorific value viscosity 35% 23.1 9.25 49.65 0.24 5605kcal / kg 1100

Embodiment 2

[0025] A kind of preparation method of novel fuel, comprises the following steps:

[0026] (1) Add 30% monoglyceride and 20-45% Span. Sodium lignosulfonate 20%, sodium carboxymethylcellulose (CMC) 3%, and xanthan gum 2% are mixed evenly to obtain an emulsifier;

[0027] (2) Dissolve 4 kg of emulsifier in 130 kg of recovered oil, stir at 45°C at a speed of 5500 rpm, and emulsify for 20 minutes;

[0028] (3) Then add 66 kg of coal-water slurry with a coal powder content of 60% to the emulsion, stir at a speed of 5500 rpm, and stir for 25 minutes, and mix evenly.

[0029] After testing, the finished product indicators are shown in the table below:

[0030] oily Moisture Ash Volatile matter Total sulfur low calorific value viscosity 65% 12.2 3.73 71.62 0.12 7482kcal / kg 500

Embodiment 3

[0032] A kind of preparation method of novel fuel, comprises the following steps:

[0033] (1) Mix 30% monoglyceride, 45% Span 20, 20% Tween 80, 3% sodium carboxymethylcellulose (CMC), and 2% xanthan gum to obtain an emulsifier;

[0034] (2) Dissolve 1.5kg of emulsifier in 50kg of recovered oil first, stir at 35°C and rotate at 5000rpm, and emulsify for 25min;

[0035] (3) Then add 48.5 kg of coal-water slurry with a coal powder content of 60% to the emulsion, the stirring speed is 4500rpmrpm, the stirring time is 20min, and the mixture is uniform.

[0036] After testing, the finished product indicators are shown in the table below:

[0037] oily Moisture Ash Volatile matter Total sulfur low calorific value viscosity 50% 16.0 11.35 60.85 0.20 5143kcal / kg 850

Abstract

The invention discloses a novel fuel and a preparation method thereof. The fuel is prepared from the following raw materials by weight: 64-33 parts of a coal water slurry with coal dust content accounting for 60%, 35-65 parts of recovery oil, and 1-2 parts of an emulsifier. The method comprises the following steps: evenly mixing the raw materials according to the emulsifier formulation; dissolving the emulsifier in recovery oil according to the above proportion, and stirring at the temperature of 30 DEG C-45 DEG C at the rotation speed of 4500rpm-5500rpm, and emulsifying for 20-30min; and then adding the coal water slurry in the emulsion, and evenly mixing at a stirring speed of 4500rpm-5500rpm for 20-30min to obtain the fuel. The method provided by the invention can increase combustion value of the coal water slurry, effectively solve the problems of resource waste and environmental pollution, and has simple process.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, specifically relates to a novel fuel, and also provides a preparation method of the novel fuel. Background technique [0002] Coal water slurry is a mixture made of 65% to 70% coal powder, 30% to 35% water and about 0.5% to 1% additives through a certain process. It is a low-pollution oil-substituting fuel, which has the advantages of convenient storage, low cost, high concentration, good fluidity, high combustion efficiency, environmental protection and energy saving, and is internationally recognized as an oil-substituting clean coal fuel. [0003] Recycled oil mainly includes repeatedly used frying oil, recycled cooking oil, and all kinds of low-quality oils in daily life, such as waste oil. Long-term consumption may cause cancer, which is extremely harmful to the human body. Contents of the invention [0004] The purpose of the present invention is to overcome the above disadvan...
