How to make use of bio fuels, the development trend
Chemical production and a serious problem: the cost of the production process using alkaline catalyst for raw materials must be such as crude oil, crude rapeseed oil and soybean oil, raw material costs accounted for 75% of the total cost. Therefore the use of cheap raw materials and improve the conversion to reduce the cost of biodiesel is the key to practical, so the United States has begun through the genetic engineering method of high oil content of the plant (see "project microalgae" method), Japan uses industrial waste oil and waste frying oil, Europe is rich in oil is not suitable for planting food crops crops on the land.
Biodiesel derived from vegetable or animal fats and oils. Oil and alcohol compounds catalyze the production of glycerol and fatty acid ester by transesterification. The preparation method mainly has: the production of biodiesel by chemical method chemical method is the use of biological oil and methanol or ethanol and other alcohols, and using sodium hydroxide (accounting for 1% of the weight of oil) or alcohol methyl sodium (Sodium methoxide) as a catalyst in acid or alkaline catalyst and high temperature (230 ~ 250 DEG C) under the transesterification reaction (transesterification), generating the corresponding fatty acid methyl or ethyl ester, after washing and drying to obtain the biological diesel oil
The hotel is used in bio oil with methanol as the main raw material, add some excipients and a certain proportion of water blending, in which no one ask will tell you, that the Internet search is not reliable, after all, is the chemical raw materials, safety first, not messing around, the bank has begun to spread around, and some the local catering industry reached 80% penetration. The future will be industrial, boiler, drying, heating, heating and so on
