Abstract:
1. A method of synthesizing a porous material comprising oxides of silicon and aluminum and being substantially free of X-ray diffraction peaks in its calcined form, wherein the material has the following properties: (a) a Bronsted acid site density as measured by temperature programmed ammonia adsorption of at least 0 005 mmol/g; (b) an alpha value of at least 0.5; (c) a specific surface area of about 50 to about 160 m (d) a total pore volume of about 0.14 to about 1.0 cm (e) a micropore volume of about 0.001 to about 0.015 cm the method comprising: (i) preparing a reaction mixture comprising water, a source of silica, a source of alumina and an organic compound selected from the group consisting of diquaternary ammonium compounds of the formula (CH (ii) heating the reaction mixture at a temperature of about 100° C. to about 200° C. for a time of about 12 hours to about 200 hours.
