Abstract
Compozitie catalitica utilizata la obtinerea dimetileterului din oxid de carbon, caracterizata prin aceea ca, în scopul obtinerii de randamente superioare, la o temperatura medie mai mica, constituita dintr-o silice cristalina în care o parte din atomii de siliciu din reteaua cristalina au fost înlocuiti cu aluminiu în astfel de proportii încît sa corespunda formulei empirice: 1Si (0,0012...0,0050) A10y în care y este cuprins între 2,0018 si 2,0075, silicea cristalina astfel modificata fiind asociata cu un amestec de oxizi si/sau saruri de cupru, zinc crom sau aluminiu, în care aluminiu poate sa fie asociat si cu cromul, concentratia atomica procentuala a fiecarui element fiind de 40...70% atomi de siliciu, 15...30% atomi de cupru, 8...15% atomi de zinc, 0...15% atomi de crom, 0,1...10% atomi de aluminiu.
