Le nqubo ithatha indawo at ingcindezi komoya kanye lokushisa 650 degrees. methanol namachibi zisetshenziswa kahle futhi cishe amaphesenti angu-80 we-formaldehyde lalungiselela le ndlela. Kodwa muva nje, kukhona ukuthuthukiswa esebenzayo indlela entsha othembisayo, esebenzisa i kulethe yensimbi-molybdenum. Cishe le ndlela yokusabela okuphuma at lokushisa 300. Kuzo zombili izindlela, ukuguqulwa has iphesenti eliphezulu kakhulu (cishe 99%).

Ukulungiselela we-formaldehyde zingenza ku dehydrogenation ka methanol. It wenziwa kanye iqhaza zinc nethusi yelikhono. Temperature Kuyadingeka - degrees 600. Nakuba le ndlela namanje kabanzi. Nokho, kubhekwa ethembisa kakhulu. It kukunika amanzi formaldehyde-DRM.

Ukusetshenziswa formaldehyde

Phezu kokuthola le nto uwukuphela side effect - a namachibi formaldehyde. ziphenduke Ngakho into enobuthi. Ngeshwa, le nqubo iyasebenza emazingeni okushisa okuvamile.

Naphezu kwakho konke lokhu, formaldehyde kabanzi ezindaweni eziningi ukukhiqizwa yezimboni. I ikhambi aqueous - methanediol - kubangela denaturation amaprotheni. Lesi sici sivumela ukusetshenziswa formaldehyde, into embonini ukushuka. Ubuye esihle ukushuka izakhiwo, okuwusizo kakhulu imithi. Formaldehyde kuyaqapheleka njengoba isinqandakuvunda enamandla kanye uyakulondoloza esihle kakhulu izinto begazi. Kodwa akugcini lapho. Ingqikithi okukhulunywa sisetshenziswa ifenisha kanye izinkuni imboni lehlanganisa tinhlelo, ngokukhethekile, kubalulekile womshini ipulangwe. Ekugcineni, formaldehyde isetshenziswa ekukhiqizeni Film-amabhayisikobho.
