Ukusetyenziswa kwe-pseudo boehmite

Okwangoku, ukusetyenziswa okuphambili kwe-pseudo-boehmite kukusetyenziswa njengezinto eziluhlaza xa kulungiswa i-alumina kunye ne-glue yokwenza i-catalyst okanye i-catalyst carrier enzima. I-alumina elungiselelwe ngokurosta i-pseudo-boehmite inendawo ephezulu kwaye isetyenziswa kakhulu njenge-catalyst kunye ne-catalyst carrier kwishishini le-petrochemical.

1. isetyenziselwa izinto zokwenza i-alumina ze-nanometer

Enye yeendlela ezibalulekileyo zokuSebenzisa i-pseudo-boehmite zizinto eziluhlaza ze-aluminium oxide. Ngokusekelwe kwiimpawu zomphezulu omkhulu, umsebenzi ophezulu kunye nokuxinana okunamandla kwezinto eziluhlaza, isetyenziselwe ukwenza iiceramics zesakhiwo ezishushu kakhulu ezifana neeceramics ze-aluminium nitride. Ukongeza, i-nano-Al2O3 ifanelekile ngokukodwa kwi-chemical mechanical polishing (CMP), yi-nano-Al2O3 njengoko amasuntswana okugaya aveliswa yi-CMP slurry angasetyenziswa kumaleko ophakathi wenkqubo yemveliso ye-IC njengezixhobo zocingo lwe-semiconductor kunye nezinto zefilimu ezifana ne-tungsten, i-aluminium, i-copper flattening, kunye ne-advanced optical glass, i-quartz crystal kunye ne-gems polishing eyahlukeneyo.

Umfanekiso -Al2O3 ungasetyenziselwa iikhemikhali zokupolisha ngoomatshini iinxalenye ezirhabaxa

2.Ukuze i-hydrogenation catalyst ifumaneke

Ukuze kuhlangatyezwane neemfuno zokusetyenziswa kwezixhobo zepetroliyam kunye neoyile ecocekileyo, iteknoloji yehydrogenated iye yasetyenziswa kakhulu, i-hydrogenation catalyst yeyona nto iphambili kwitekhnoloji yehydrogenation, esetyenziselwa i-hydrogenation catalyst. I-gamma alumina carrier idla ngokwenziwa yi-diaspore encinci ngokubhaka amanzi emzimbeni, inomphezulu othile, ingena kwaye isasazeke kakuhle, umphezulu unee-acidic center ezahlukeneyo. Amandla angcono oomatshini kunye nokuzinza kobushushu, kunye neempawu ezingabizi kakhulu.

Iikhatalyst zemizobo zibalulekile ekuvelisweni kweemveliso zepetroliyam

Kwishishini lanamhlanje lokucocwa kweoyile kunye neekhemikhali, ngaphezulu kwe-90% yenkqubo yokusabela kweekhemikhali yenziwa ngenkqubo yokulungisa, ngoko ke i-catalyst ibe sisitshixo sokufezekisa inkqubo entsha yokucoca kunye neekhemikhali, uphuhliso lwemveliso entsha. Kwishishini lokucoca ioyile, ii-catalysts eziqinileyo zisetyenziswa rhoqo, ezakhiwe yi-carrier kunye ne-active component. I-catalyst yinxalenye ekhethekileyo ye-catalyst eqinileyo, enokunyusa indawo ethile yomphezulu, iphucule ukumelana nobushushu kunye namandla oomatshini. I-catalyst IFAKA iintlobo ezininzi ze-catalyst, ezinje: i-alumina, isihluzo se-molecular, i-silica gel, i-silica gel, i-activated carbon kunye ne-diatomaceous earth. Nangona kunjalo, ubungakanani be-alumina catalyst bubangela ngaphezulu kwesiqingatha senani lilonke le-catalyst catalyst. I-catalyst ye-Catalytic cracking (FCC) yintloko yenkqubo yokulungisa i-catalytic. Njengoko i-oyile ekrwada yehlabathi inzima kwaye ingaphantsi, kwi-catalytic cracking raw material exuba ioyile enzima, i-residual oil ibe yindlela esetyenziswa kakhulu yokucubungula, ngoko ke i-catalyst ye-oyile catalytic cracking (FCC) kufuneka ibe yi-heavy oil molecular disffusion ye-big hole, kwaye i-big hole embindini kufuneka ibe ne-acid density efanelekileyo, kwi ukuze kuphuculwe amandla okuqhekeka kwe-catalyst yee-macromolecular compounds kwizixhobo eziluhlaza. I-alumina esebenzayo isetyenziswa rhoqo ukuphucula i-catalyst matrix. Umthamo omkhulu we-pore ulungelelanisa ukusasazeka kwee-macromolecular compounds kwi-catalyst particles, ngelixa indawo ephezulu ethile ilungelelanisa ukusasazeka kwesinyithi esisebenzayo, ukuze kuphuculwe ukusebenza kwe-catalyst.

3. Isetyenziswa njenge-adhesive

I-quasi thin diaspore carrier esetyenziswa njenge-bonding agent ayincedi nje kuphela ekubumbeni, kodwa iya kuchaphazela nokusebenza kwe-catalyst, abaphandi kwi-flue gas denitration selective catalytic reduction Ce – Mn/TiO2 catalyst kwinkqubo yokudibanisa i-thin diaspore njenge-bonding agent, bafumanise ukuba ayiphuculi nje kuphela amandla oomatshini e-catalysts, kodwa ikwaphucula ne-denitration surfactant selective catalyst.

4. lungisa i--Al2O3 coating

Umsebenzi wokugquma umaleko kumphezulu we-carrier coating carrier kukwandisa indawo ethile yomphezulu wendlela esetyenziswa rhoqo, i-gamma alumina yenye yezona zinto zisetyenziswa kakhulu zokugquma, enommandla othile ophezulu, inceda ukusasazwa ngempumelelo kwenkqubo yokufunxa, ukulungiswa kwe-gamma alumina coating esetyenziswa rhoqo kwi-AlOOH precursor sol, i-alumina sol ibe yi-diaspore encinci njengezinto ezikrwada, ukulungiswa, ngokusebenzisa indlela yenkqubo ye-acid peptization elula ukuyilawula, ingasetyenziselwa imveliso yemizi-mveliso.
