MTBE yog dab tsi?
Methyl tert-butyl ether, feem ntau hu ua MTBE, muaj CAS naj npawb 1634-04-4 thiab yog ib qho high-octane oxygenated compound siv los ua cov roj av sib xyaw. Nws yog tsim los ntawm reacting methanol nrog isobutylene. MTBE muaj cov ntsiab lus oxygen qis dua methanol thiab qis qis qis ntawm vaporization, uas txhim kho qhov pib txias thiab roj vaporization thaum sib xyaw rau hauv roj av. MTBE kuj tseem tuaj yeem tawg rov qab mus rau isobutylene rau kev siv roj hmab thiab tshuaj lom neeg.
Puas yog MTBE tseem siv hauv roj av?
MTBE tsis siv rau hauv cov roj av hauv Tebchaws Meskas lawm thiab tau raug cuam tshuam ntau hauv lwm lub khw tsim khoom. Hauv Tebchaws Meskas, Txoj Cai Huv Huv Huv tau hloov kho cov kev pabcuam roj av pib txhawb cov pa oxygenates, tab sis MTBE feem ntau tau hloov los ntawm ethanol tom qab California txwv nws hauv xyoo 2003 vim muaj kev txhawj xeeb txog dej hauv av. Xyoo 2005 US Energy Policy Act tau tshem tawm tsoomfwv cov kev xav tau oxygenate, thiab kev siv MTBE hauv Asmeskas cov roj av poob qis heev. Cov European Union txwv tsis pub siv MTBE, nrog rau feem ntau cov tswvcuab lub tebchaws hloov mus rau ethanol lossis lwm cov pa oxygenates, thiab Canada thiab Australia tau txo qis kev siv MTBE hauv kev pom zoo ntawm ethanol blends.
MTBE Puas Tseem Siv Niaj Hnub No?
MTBE tseem siv tau nyob rau thaj tsam ntawm Asia, suav nrog Tuam Tshoj, Is Nrias teb, thiab qee lub tebchaws Esxias yav Qab Teb Hnub Tuaj, thiab hauv thaj chaw ntawm Middle East, qhov chaw ethanol yuav raug txwv lossis qhov chaw uas twb muaj lawm refining infrastructure yog configured rau ether oxygenates. Hauv cov khw no MTBE tseem ua haujlwm ua octane enhancer thiab oxygenate hauv cov roj av sib xyaw.
Cov khoom tseem ceeb thiab kev txiav txim siab zoo
MTBE yog ib qho ntshiab, volatile, flammable kua nrog ib tug yam ntxwv ether tsw. Nws tsuas yog me ntsis soluble hauv dej, uas ua rau muaj teeb meem keeb kwm hauv av hauv av thaum tso cov tso tsheb hlau luam tso rau hauv av. Kev lag luam MTBE rau cov roj sib xyaw yog muab rau cov lus qhia nruj, thiab cov neeg yuav khoom yuav tsum paub meej txog qib, purity, thiab cov roj los yog kev lag luam nrog tus neeg muag khoom.
Kev nyab xeeb thiab ib puag ncig kev ceeb toom
MTBE yog flammable thiab yuav tsum tau muab cia kom deb ntawm qhov hluav taws kub nrog rau hauv av kom zoo thiab qhov cua. Nws tuaj yeem ua rau khaus rau lub qhov muag thiab tawv nqaij, thiab yuav tsum zam kom tsis txhob muaj cov pa ntau ntxiv. Vim nws txoj kev txav mus los hauv av thiab dej, MTBE tuav thiab khaws cov tshuab yuav tsum muaj xws li kev kuaj pom thiab kev tiv thaiv thib ob los tiv thaiv cov dej hauv av.
Cov lus nug nquag
Puas yog MTBE tseem siv roj av?MTBE tsis siv rau hauv Teb Chaws Asmeskas cov roj av thiab tau raug faib tawm ntau hauv EU, tab sis nws tseem siv nyob rau hauv thaj chaw ntawm Asia thiab Middle East.
Vim li cas MTBE raug txwv hauv Tebchaws Meskas?MTBE raug txwv nyob hauv California xyoo 2003 vim yog dej hauv av paug, thiab 2005 US Energy Policy Act tau tshem tawm tsoomfwv cov kev xav tau oxygenate, xaus nws qhov tseem ceeb hauv Teb Chaws Asmeskas siv.
Dab tsi hloov MTBE hauv Asmeskas roj av?Ethanol tau dhau los ua cov pa oxygenate thiab octane tseem ceeb - txhim kho cov khoom sib xyaw hauv Asmeskas cov roj av tom qab MTBE raug txiav tawm.
Puas yog MTBE tseem siv hauv Suav teb?Yog lawm, MTBE tseem siv los ua cov roj av sib xyaw ua ke hauv Suav teb, nrog rau ntau lub khw Asian thiab Middle East.
Puas yog MTBE txaus ntshai?MTBE yog cov kua hluav taws kub uas tuaj yeem ua rau lub qhov muag thiab tawv nqaij, thiab yuav tsum zam kom tsis txhob muaj vapor ntau; nws kuj ua rau muaj kev pheej hmoo hauv av yog tias tso tawm.
MTBE yog dab tsi?MTBE yog tsim los ntawm cov tshuaj tiv thaiv methanol nrog isobutylene.
