Biodiesel Production Line suppliers What drawback does derv of biology of chemically law complex have?
The chemical law production of biology derv is to use the low carbon alcohol such as biology grease and methanol or alcohol, use oxyhydrogen to change sodium (the 1%) that holds grease weight or mellow armour natrium (Sodium Methoxide) as catalyst, in acidity alkalescent perhaps activator and high temperature (250 ¡æ of 230 ¡« ) allot exchange giving birth to ester to react (Transesterification) , generate ester of corresponding fatty acid armour or second ester, again classics catharsis is dry get biology diesel oil namely. Methanol or alcohol can be used circularly in producing a course, manufacturing facilities is as identical as the common device that make oil, 10% by-product glycerine of the left and right sides arise in producing a course. By biology derv machines equipment manufacturer to collect fontal biology to be everybody’s detailed introduction below.
But derv of biology of chemical law synthesis has the following drawback: Reaction temperature taller, technology is sophisticated; React the methyl alcohol of excessive is used in the process, follow-up craft must have corresponding alcohol to reclaim device, processing process heavy and complicated, specific power consumption is tall; The water in grease raw material and free fatty acid can affect biology derv badly to get rate and quality; The product is rarefied and complex, ester changes child to be hard to reclaim; The by-product that reaction generates be hard to purify, and the liquid waste with much generation of activator of use soda acid, useless alkaline (acerbity) fluid is discharged cause pollution easily 2 times to wait to the environment. Chemical law production still has a cost problem that nots allow to ignore: Alkalescent activator is used to ask raw material must be crude oil in producing a course, mix without the rapeseed oil of abstraction for instance soya-bean oil, 75% what raw material cost holds totle drilling cost. Because this is used cheap raw material and rise change reducing cost thereby is biology derv whether practical practicality key, because of this United States oneself the plant that begins to study high oily content through gene project method, japan uses industry to waste oil and useless frying oil, europe is the crop that plants rich oil fat on the land that does not suit to grow grain.
