Catalytic reforming inzira yakakosha muindasitiri yekunatsa peturu, yakanangana nekusimudzira kunaka kwepeturu. Pakati pematanho akasiyana ekugadzirisa,Kuenderera mberi Catalyst Regeneration(CCR) shanduko inomira pachena nekuda kwekuita kwayo uye kushanda kwayo mukugadzira yakakwira-octane peturu. Chinhu chakakosha cheichi chiitiko ndechekuvandudza catalyst, iyo inoita basa rakakosha mukufambisa kemikari inodiwa pakushandura naphtha kuita zvikamu zvakakosha zvepeturu.
ChiiKuchinja kweCCR?
CCR reforming inyanzvi yemazuva ano yekunatsa iyo inobvumira kuenderera mberi kwekuvandudzwa kweiyo catalyst inoshandiswa mukugadzirisa maitiro. Iyi nzira inosiyana neyechinyakare batch reform, uko iyo catalyst inobviswa nguva nenguva kuti ivandudzwe. MuCCR reforming, iyo catalyst inoramba iri mureactor, uye kuberekwazve kunoitika mune imwe nzvimbo yakasiyana, zvichibvumira kushanda kwakasimba uye kuwedzera kwepamusoro. Iyi inoenderera mberi haingogadzirisi goho repamusoro-octane peturu asi zvakare inosimudzira kugona kwese kwekuita basa rekunatsa.
Basa Rezvinokonzeresa Mukugadzirisa
Catalysts zvinhu zvinomhanyisa kuita kwemakemikari pasina kudyiwa mukuita. Muchirevo cheCCR kuchinja, iyo catalyst yakakosha kune akati wandei maitiro, kusanganisira dehydrogenation, isomerization, uye hydrocracking. Aya maitirwo anoshandura mahydrocarbon akatwasuka kuita mabranched-chain hydrocarbons, ane chiyero chepamusoro cheoctane uye anodiwa zvakanyanya mukugadzira peturu.
Iwo anonyanya kushandiswa macatalysts muCCR reforming ndeye platinum-based catalysts, inowanzo tsigirwa paaluminium. Platinamu inofarirwa nekuda kwekuita kwayo kwakanaka uye kusarudza mukusimudzira maitiro anodiwa. Uyezve, kushandiswa kwebifunctional catalyst, iyo inobatanidza nzvimbo dzose dzesimbi neasidhi, inobvumira kushanduka kwakanyatsonaka kwe naphtha muzvigadzirwa zvepamusoro-octane. Nzvimbo dzesimbi dzinofambisa dehydrogenation, nepo nzvimbo dzeasidhi dzichikurudzira isomerization uye hydrocracking.
Ndeipi Catalyst Inoshandiswa muReformer?
MuCCR kugadzirisa, iyoprimary catalystrinoshandiswa rinowanzoita platinamu-aluminium catalyst. Iyi catalyst yakagadzirirwa kutsungirira mamiriro akaoma ekugadzirisa maitiro, kusanganisira kupisa kwakanyanya uye kumanikidzika. Chikamu cheplatinamu ndicho chinokonzera chiitiko checatalytic, ukuwo tsigiro yealuminium inopa kugadzikana kwechimiro uye nzvimbo yepasi kuti maitiro aitike.
Pamusoro peplatinamu, mamwe masimbi akadai serhenium anogona kuwedzerwa kuwedzera mashandiro echatalyst. Rhenium inogona kuvandudza kuramba kweiyo catalyst kudzima uye kuwedzera goho rose repamusoro-octane peturu. Iko kuumbwa kweiyo catalyst kunogona kusiyanisa zvichienderana nezvinodiwa chaizvo zvekunatsa maitiro uye inodiwa chigadzirwa.
Mhedziso
Reforming catalysts, kunyanya mumamiriro ezvinhu eCCR reforming, akakosha mukugadzirwa kwepeturu yemhando yepamusoro. Sarudzo yecatalyst, kazhinji platinamu-aluminium kuumbwa, inokanganisa zvakanyanya kushanda uye kushanda kwemaitiro ekugadzirisa. Sezvo kudiwa kwemafuta akachena uye anoshanda kwakawanda kuri kuramba kuchikwira, kufambira mberi kwehunyanzvi hwekuita tekinoroji kuchaita basa rakakosha mukuumba ramangwana rekugadzirwa kwepeturu. Kunzwisisa kuomesesa kweizvi zvinokonzeresa uye mabasa azvo kwakakosha pakukwenenzvera nyanzvi nechinangwa chekusimudzira mashandiro avo uye kusangana nemusika unobuda zvinodiwa.
