據全國(guo)(guo)人大(da)代(dai)表、國(guo)(guo)家能源集團包(bao)頭化(hua)工(gong)公司執行董(dong)事(shi)、總經理賈潤(run)安介紹，煤基混(hun)(hun)合戊(wu)(wu)烯(xi)(xi)(xi)作為(wei)煤制(zhi)烯(xi)(xi)(xi)烴工(gong)藝過程中的副產(chan)(chan)品(pin)，富(fu)含(han)(han)碳五烯(xi)(xi)(xi)烴，同時(shi)含(han)(han)有(you)部分碳六烯(xi)(xi)(xi)烴，碳五及以上餾份含(han)(han)量大(da)于97.5%。混(hun)(hun)合戊(wu)(wu)烯(xi)(xi)(xi)含(han)(han)量大(da)于50.0%，并以正戊(wu)(wu)烯(xi)(xi)(xi)、異(yi)戊(wu)(wu)烯(xi)(xi)(xi)和環戊(wu)(wu)烯(xi)(xi)(xi)為(wei)主要(yao)組分。煤基混(hun)(hun)合戊(wu)(wu)烯(xi)(xi)(xi)與石油(you)碳五從原料(liao)、生產(chan)(chan)工(gong)藝、化(hua)學結構和用途都(dou)不同。經過產(chan)(chan)品(pin)銷售(shou)和下(xia)游市(shi)場的產(chan)(chan)品(pin)開發，煤基混(hun)(hun)合戊(wu)(wu)烯(xi)(xi)(xi)所含(han)(han)若干(gan)烯(xi)(xi)(xi)烴組分是重(zhong)要(yao)的有(you)機合成原料(liao)，可(ke)作為(wei)精細化(hua)工(gong)原料(liao)，可(ke)有(you)效增加化(hua)工(gong)類(lei)產(chan)(chan)品(pin)的經濟效益。

以(yi)前，由于煤(mei)基混(hun)合戊烯沒有(you)相應(ying)的(de)(de)(de)國(guo)家(jia)標(biao)準，國(guo)家(jia)參照石油工(gong)業SH／T1789-2015《工(gong)業用(yong)裂(lie)解碳五(wu)》標(biao)準，對煤(mei)基混(hun)合戊烯征收較(jiao)高額(e)度的(de)(de)(de)消費稅，增大了煤(mei)化(hua)(hua)工(gong)企業的(de)(de)(de)稅費負擔，同時從(cong)某種意(yi)義上(shang)說也限制了下游以(yi)煤(mei)基混(hun)合戊烯為原料的(de)(de)(de)精細化(hua)(hua)工(gong)的(de)(de)(de)生產和發展。

賈潤安建(jian)議，煤(mei)(mei)(mei)(mei)(mei)(mei)基混(hun)合戊(wu)烯(xi)與石油碳五從原(yuan)料、生產(chan)工(gong)(gong)藝、化學結構(gou)和用(yong)途都不同，如(ru)今(jin)《煤(mei)(mei)(mei)(mei)(mei)(mei)基混(hun)合戊(wu)烯(xi)》國(guo)家標準(zhun)也(ye)已經發布(bu)，建(jian)議有關(guan)單位從保障國(guo)家能源安全及現代煤(mei)(mei)(mei)(mei)(mei)(mei)化工(gong)(gong)產(chan)業發展的(de)(de)角度，參照(zhao)(zhao)《煤(mei)(mei)(mei)(mei)(mei)(mei)基混(hun)合戊(wu)烯(xi)》國(guo)家標準(zhun)，統籌(chou)規劃煤(mei)(mei)(mei)(mei)(mei)(mei)基混(hun)合戊(wu)烯(xi)產(chan)品(pin)銷售稅(shui)收(shou)標準(zhun)，在征(zheng)(zheng)收(shou)環(huan)節上，對煤(mei)(mei)(mei)(mei)(mei)(mei)基混(hun)合戊(wu)烯(xi)消(xiao)費稅(shui)由生產(chan)環(huan)節征(zheng)(zheng)收(shou)改(gai)為消(xiao)費環(huan)節征(zheng)(zheng)收(shou)，對用(yong)于(yu)油品(pin)添加(jia)劑等用(yong)途的(de)(de)煤(mei)(mei)(mei)(mei)(mei)(mei)基混(hun)合戊(wu)烯(xi)按(an)照(zhao)(zhao)其銷售價格，以合理比例征(zheng)(zheng)收(shou)消(xiao)費稅(shui)，對用(yong)于(yu)下游化工(gong)(gong)原(yuan)料的(de)(de)煤(mei)(mei)(mei)(mei)(mei)(mei)基混(hun)合戊(wu)烯(xi)免于(yu)征(zheng)(zheng)收(shou)消(xiao)費稅(shui)。
