A new crystalline zinc (silico)aluminophosphate molecular sieve designated SSZ-90 is disclosed. SSZ-90 is isostructural with the DFO framework type and is synthesized using an ionic liquid as both the solvent and the structure directing agent. The ionic liquid [Q.sup.+A.sup.] comprises a cation (Q.sup.+) selected from the group consisting of 1,3-diisopropylimidazolium, 1,3-diisobutylimidazolium, and 1-isopropyl-3-isobutylimidazolium and an anion (A.sup.) which is not detrimental to the formation of the molecular sieve.

This invention relates to a novel family of hierarchical metallophosphates which are represented by the empirical formula:

[00001]$R_r^{+}{M}_m^{2+}E{P}_x{\mathrm{Si}}_y{O}_z$

where M is a divalent framework metal such as magnesium or zinc, R is an organoammonium cation, E is a trivalent framework element such as aluminum or gallium, and in which the hierarchical metallophosphates possess a pore structure having at least 75% of its total surface area being micropore surface area and a hierarchy factor of at least 0.09, said hierarchy factor defined as [(V.sub.micro/V.sub.tot)*(S.sub.meso/S.sub.tot)], where V.sub.micro and V.sub.tot represent the micropore volume and total pore volume below 450 , respectively, and S.sub.meso and S.sub.tot represent the non-micropore surface area and total surface area, respectively. The hierarchical metallophosphates of the invention are of use in hydrocarbon conversion processes such as hydroisomerization or dewaxing.

Disclosed is a process for producing a jet fuel, comprising a step of converting an alcohol stream in a fluidized bed, a jet fuel and a plant associated with said process. The process involves the following steps: (a) converting a C1 to C6 alcohol stream to produce a mixture containing paraffins, olefins, aromatics, and water; (b) separating water from the mixture; (c) oligomerizing olefins; and (d) alkylating aromatics from the mixture; (e) forming a stream of hydrocarbons to be hydrogenated; (f) hydrogenating the stream of hydrocarbons to be hydrogenated; (g) recovering at least one jet fuel fraction from the hydrogenated hydrocarbon stream.

Conversion step (a) is carried out in a reaction zone comprising at least one fluidized catalytic bed.

In the mixture of paraffins, olefins, aromatics and water produced in conversion step (a), the ratio of the mass of C3+ olefins to the total mass of olefins is greater than or equal to 0.8.
