ABSTRACT:
This invention relates to a novel dioctahedral smectite layered clay, a process for preparing the clay and a process using the clay. The clay is characterized in that the aluminum can be substituted by gallium and the silicon can be substituted by germanium. Therefore, some of the possible clays that can be prepared are gallium/silicon, gallium/germanium, or aluminum/germanium smectite clays. The clay is prepared from a reaction mixture containing reactive sources of the metals, i.e., aluminum, silicon, gallium and germanium, a templating agent and water. This reaction mixture is reacted at a pH of about 8.5 to about 14, a temperature of about 150.degree. to about 210.degree. C. for a time of about 1 to about 20 days to give a desired composition. The clay compositions of the instant invention can be used to catalyze various hydrocarbon conversion processes such as alkylation and hydrocracking.
