Nta & Qhov Zoo
Clean-Kub lwm yam roj
Tsis muaj leej faj cov ntsiab lus thiab tsis tshua muaj NOx thiab feem emissions, dimethyl ether gas combustion tsim cov pa phem tsawg dua li cov pa roj carbon monoxide, txhawb cov huab cua huv.
Siab Cetane & Zoo heev combustion
Nws tus lej cetane siab ua rau muaj txiaj ntsig zoo, khob- pub dawb combustion hauv compression ignition engines, tsuas yog yuav tsum tau hloov kho me me rau cov tshuab hluav taws xob diesel uas twb muaj lawm.
LPG-Zoo li Kev Tswj & Infrastructure
Nws tuaj yeem ua kua dej ntawm qhov tsis tshua muaj siab thiab khaws cia hauv cov tso tsheb hlau luam zoo sib xws thiab thauj los ntawm LPG infrastructure uas twb muaj lawm, ua kom yooj yim rau kev ua lag luam.
Ntau yam tshuaj Chemical Feedstock
Nws tuaj yeem ua tus thawj coj los tsim cov olefins qis (xws li ethylene thiab propylene) thiab lwm yam khoom muaj txiaj ntsig siab, muab cov khoom tsis yog - roj av.
Eco-Tus phooj ywg Propellant
Raws li tsis yog -ozone- depleting cov khoom uas muaj peev xwm ua kom lub ntiaj teb no qis, nws yog ib qho kev hloov zoo rau CFCs thiab HFCs hauv cov khoom aerosol.
Cov yam ntxwv ua haujlwm
Dimethyl ether gas ua haujlwm feem ntau yog lub zog thauj khoom thiab lub tsev tshuaj lom neeg. Raws li ib tug roj, nws undergoes combustion zoo ib yam li cov hydrocarbons tab sis nrog cov ntsiab lus ntawm cov pa oxygen uas txhawb kev hlawv ntau dua. Nws yog feem ntau khaws cia thiab tuav ua cov roj liquefied nyob rau hauv nws tus kheej vapor siab (~ 5-6 bar ntawm ambient kub). Hauv kev sib xyaw tshuaj, nws tuaj yeem hloov pauv ntawm lub cev qhuav dej lossis lwm yam txheej txheem catalytic. Nws lub siab vapor siab thiab hnyav hnyav ua rau nws ua haujlwm zoo li lub zog, tshem tawm cov khoom lag luam los ntawm cov kaus poom aerosol thaum ua miscible nrog ntau cov qauv.
Thawj daim ntawv thov teb
Tsheb thauj mus los
Raws li kev hloov lossis sib xyaw ua ke rau diesel hauv cov tsheb thauj khoom, tsheb npav, thiab tejzaum nws cov cav ntoo marine; kuj tshawb nrhiav roj hlwb.
Aerosol Propellant
Siv dav hauv cov khoom tu tus kheej (hairsprays, deodorants), tshuaj ntxuav tsev, thiab cov tshuaj txau ua "ntsuab" propellant.
Cov Khoom Siv Tshuaj
Rau kev tsim cov olefins (ntawm DME- mus rau- txheej txheem olefins), acetic acid, dimethyl sulfate, thiab lwm yam tshuaj.
Chaw Nyob & Ua Lag Luam Roj
Ib qho huv huv - hlawv roj ua noj thiab cua sov, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas tsis muaj cov kav dej, feem ntau sib xyaw nrog LPG.
Lub zog tiam
Roj rau turbines thiab generators nyob rau hauv faib hluav taws xob systems.
Cov neeg siv khoom sib koom tes Case
Ib lub nroog loj hauv nroog pej xeem txoj cai tswjfwm txhawm rau txo qis cov pa phem los ntawm nws cov tsheb npav diesel tab sis ntsib cov teeb meem nrog tus nqi siab thiab kev tsim kho vaj tse ntawm lwm cov roj hluav taws xob xws li hluav taws xob lossis hydrogen. Peb tau koom tes nrog lawv ntawm qhov kev sim ua haujlwm kom rov tsim kho ib feem ntawm lawv lub nkoj kom khiav ntawm cov roj dimethyl ether. Peb tau muab cov kev daws teeb meem tiav, suav nrog cov khoom siv siab tshaj -purity dimethyl ether gas, tsim thiab kev teeb tsa ntawm lub chaw nres tsheb refueling, thiab kev txhawb nqa rau lub cav calibration. Cov tsheb npav khiav ntawm cov roj dimethyl ether tau pom qhov ze - tshem tawm tag nrho cov pa taws ( pa taws - tso pa tawm), txo qis hauv NOx emissions, thiab ua haujlwm ntsiag to. Tus kws tsav dav hlau tau ua pov thawj qhov kev ua haujlwm tau zoo thiab cov txiaj ntsig ib puag ncig. Raws li qhov kev vam meej no, tam sim no txoj cai tab tom npaj qhov loj dua - nplai tawm, siv cov roj dimethyl ether ua tus ncej tseem ceeb ntawm nws lub tswv yim kom ua tiav huab cua huv hauv nroog. Cov ntaub ntawv no qhia txog lub luag haujlwm tseem ceeb ntawm cov roj dimethyl ether yog qhov siv tau, poob - hauv kev daws rau decarbonizing hnyav - lub luag haujlwm thauj.
