Engeri z’ebirungo ebiziyiza obutundutundu (particulate catalysts).
Ebiziyiza obutundutundu birina ekitundu ekinene eky’okungulu ekitongole n’obuziba, okulongoosa ennyo obulungi bw’ensengekera. Ebirungo byaffe ebya methanol-to-aromatics catalysts ne hydrogenation catalysts byonna bikoleddwa mu ngeri y’obutundutundu, nga byoleka okutebenkera okulungi ennyo n’okulonda. Mu byo, ebiva mu ssefuliya ya molekyu za zeolite nabyo birina topology ez’enjawulo nga FAU/MWW.
Ebiziyiza obutundutundu (particulate catalysts) kibiina kikulu eky’ebintu ebikozesebwa ennyo mu nnimiro z’eddagala, obutonde, n’amasoboza. Enkula yazo ey’enjawulo ey’obutundutundu n’enkola yazo ey’okuziyiza (catalytic performance) zizifuula ekitundu ekikulu mu nkola nnyingi ez’amakolero. Okukozesa ebiziyiza obutundutundu okusinga kwesigamiziddwa ku buwanvu bwabyo obw’enjawulo obw’okungulu, okusaasaana okulungi, n’emirimu gy’okutabula, ekiyinza okukendeeza ennyo ku maanyi g’okukola n’okulongoosa omutindo gw’ensengekera n’okulonda mu nsengekera z’eddagala.
Omulimu gw’okutabula (catalytic activity) ogw’obutundutundu obuziyiza (particulate catalysts) okusinga gusibuka mu bifo byabwe ebikola ku ngulu. Ebifo bino bisobola okunyiga molekyo z’ebirungo ebikola, ne kitumbula okumenya n’okutondebwa kw’enkolagana z’eddagala. Enteekateeka y’obutundutundu tekoma ku kwongera ku kitundu ky’okukwatagana wakati w’ekirungo ekiziyiza n’ebirungo ebikola naye era eyamba okutambula n’okusaasaana mu riyakita, okulongoosa obulungi bw’okutambuza ebizito. Ekirala, ebiziyiza obutundutundu bitera okuba n’amaanyi ag’ebyuma aga waggulu, nga bigumira okwambala kw’omubiri n’okukulukuta kw’eddagala mu nkola y’ensengekera, ekyongera ku bulamu bwabyo obw’obuweereza.
