To adapt to the market change at home and abroad, and the significant features of scale merits regarded as the development trend in oil industry, Henan Hi-tech Kingdo Industrial Co., Ltd has sucessfully developed the fuel used biodiesel project by taking unfit human consumption and waste animal and vegetables oil as raw meterials, which extends the productivity and reduces the cost.  It is the green health concept that guiding the enterprise brand benefit and temporizing to the requirement of market development.

The main raw materials of the biodiesel:

soybean oil, rapeseed oil, sunflower oil, palm oil
animal oil
acidulated oil
gutter oil

Biodiesel process:

(1) Physical degumming: first of all, using oil hydration or phosphoric acid-etching method, remove the phospholipids and colloid and other substances, and then preheating, dehydration the oil.

(2) Methanol esterification: adding excess methanol into the raw oil material, with the acid catalyst, conduct pre-esterification, changing free acid into methyl ester.

 (3) Continuous ester exchange:  the pre-esterification oil together with methyl alcohol, adding little NaOH as catalyst, under a certain temperature and atmospheric pressure, conduct ester exchange, then get methyl ester.   Using two-step reaction, through a specially designed separator continuously eliminate the glycerin engendered in the reaction, make the ester exchange continuously.

(4) Gravity precipitation, water washing and stratification.

(5) Glycerol separated from crude methyl ester.

(6) Biodiesel refined.

The equipment is used to chemical industry field, raw material can be catering waste oil, acid oil etc, used cooking oil etc.

It contains the international advanced pre-processing section, esterification process and distillation process, and it meets

the ASTM stankdard.Bio-diesel is extracted from animal fats,plant oil, and widely used for trucks, tractors, ships, etc. It refers

to use oil crops, such as soybean, rapeseed, cotton, palm, wild oil plant and engineering micro algae and other aquatic plant

oils and animal fats, food waste oil as raw oil material, through ester exchange process , producing a kind of reactivity diesel

fuel which could instead of petroleum diesel.Bio-diesel is one kind of biomass energy, and it is a kind of long chain fatty acid

mono-alkyl esters getting from the biomass utilization technology such as ester exchange. Bio-diesel is a mixture of high oxygen

content of complex organic compounds, and these compounds are mainly large molecular weight , and including to almost all types

of oxygen-containing organic compounds, such as, ether, aldehyde, ketone, phenol, organic acids, alcohols, etc.Compound Bio-diesel

is extracted from raw material such as abandoned animal fats and pliant oil, used oil and a by-product of oil refinery, added catalyst,

synthesized by special equipment and special technology.

The prodution steps are as follows:
1. Preprocessing section of bio-oil: when heated to 65-70°C, bio-oil is leached to remove impurities.
2. Drying section: bio-oil without impurities is dehydrated and dried.
3. First esterification reaction: adding bio-oil dehydrated to methanol including 3% sulfuric acid, first esterification reaction starts, and it will take 1.5—2.5 hours.
4. Second esterification reaction: this esterification reaction will take 9—12 hours.
5. Vacuum drying section: Second esterification reactants are dried with vacuum, removing moisture, reducing water content below 3%.
6. Distillation section: with vacuum state, second esterification reactants after vacuum drying section are heated to 220°C, biodiesel forms by steaming. Then cooling biodiesel to be liquid, the liquid biodiesel is just finished biodiesel.
7. Methanol fine-distillation: after biodiesel is isolated, the remaining methanol liquid is distilled to form methanol. Methanol cooled can be reused.
Bio-oil can be plant oil, animal oil or high acid-value waste oil.
