The present invention relates to a molecular sieve having the SFE structure, a process for producing same and use thereof. The process includes a step of crystallizing a mixture comprising a first oxide source, a second oxide source, an organic template and water to obtain a molecular sieve having the SFE structure, wherein the organic template is preferably 4-dimethylamino pyridine. As compared with the prior art, the process exhibits such merits as significantly reduced crystallization duration.

The present invention relates to an SCM-10 molecular sieve, a process for producing same and use thereof. The molecular sieve has an empirical chemical composition as illustrated by the formula the first oxide.Math.the second oxide, wherein the ratio by molar of the first oxide to the second oxide is less than 40, the first oxide is at least one selected from the group consisting of silica and germanium dioxide, the second oxide is at least one selected from the group consisting of alumina, boron oxide, iron oxide, gallium oxide, titanium oxide, rare earth oxides, indium oxide and vanadium oxide. The molecular sieve has specific XRD pattern and can be used as an adsorbent or a catalyst for converting an organic compound.

Said 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 the water from the mixture to form a water-depleted mixture; the water-depleted mixture is separated and/or treated to recover hydrocarbons;

The process includes adding, in step (a) of converting the C1 to C6 alcohol stream, a carbon dioxide-containing stream, and jointly converting the carbon dioxide to carbon monoxide in step (a) of converting the C1-C6 alcohol stream.
