    Abstract: Crystalline galloaluminosilicates having an X-ray diffraction pattern substantially the same as that of an MFI-zeolite and a composition in terms of mole ratios of oxides as follows: 0.9 ↓∃0.2M2/n0.Al203. a Ga203. b SiO2.zH2O wherein M is a cation, n is the valence of the cation, a has a value between 0.0001 and 2, b has a value of at least 12 and z has a value of from 0 to 40. A process for the production of the crystalline galloaluminosilicates which comprises crystallising at elevated temperature a gel comprising (i) a source of silica (SiO2), (ii) a source of alumina (Al2O3), (iii) a source of gallia (Ga2O3), (iv) a mineralising agent selected from oxides, hydroxides and salts of alkali and alkaline earth metals (X2/nO wherein n is the valency of X), (v) an organic base (B) and (vi) ROH wherein R is H and/or lower alkyl, in the following molar proportions:$(5,)$SiO2:X2/nO=1000:1 to 50:1, SiO2:B=50:1 to 1:20, SiO2:ROH=less than 1:10, Al2O3: Ga203=500:1 to 1:100. Ion-exchanged forms, calcinated forms and steam-treated forms ofthe crystalline galloaluminosilicates are also described. Such materials can be used as catalysts and catalyst supports. The steam-treated form is particularly useful as a catalyst for the production of aromatic hydrocarbons from C2 to C12 hydrocarbon feedstocks.

    Abstract: A spray nozzle for fire control produces a spray of gas and liquid having an oval transverse cross-section and comprises a mixing chamber having an oval transverse cross-section adapted to induce a toroidal mixing pattern in pressurised gas and liquid introduced to the mixing chamber (6) through a plurality of inlets (10, 8). In a preferred embodiment the mixing chamber (6) is toroidal. The spray nozzle may be used in fire control systems in vehicles or other confined spaces.
