Abstract: Method of operating a compression ignition engine on ether containing fuel obtained by on board conversion of an alcohol containing primary fuel, and a system for use in the method. The alcohol containing primary fuel is heated within a dehydration reactor by indirect heat exchange with ether containing fuel prepared in the dehydration reactor by dehydrating the alcohol containing primary fuel. The ether containing fuel is cooled prior to withdrawal from the reactor as a result of the indirect heat exchange with the alcohol containing primary fuel.

Abstract: A method of operating a compression ignition engine on diethyl ether containing fuel obtained by conversion of a primary ethanol containing fuel, wherein the primary fuel is catalytically converted to a diethyl ether containing fuel at a constant minimum and maximum flow rate through a catalytic reactor. The thus prepared ether containing fuel is passed to a buffer tank and a system for use in anyone of the preceding claims comprising a first fuel tank for holding a primary ethanol containing fuel; an ethanol dehydration reactor connected to the first fuel tank at inlet of the reactor and to a second buffer tank connected at outlet of the reactor; the second buffer tank holding a diethyl ether containing fuel being formed in the dehydration reactor is further connected to a compression ignition engine; the second buffer tank is provided with at least a sensor for detecting an upper fuel level and at least a second sensor for detecting a lower fuel level in the buffer tank.

Abstract: Method for the preparation of a compression ignition engine fuel, comprising the steps of providing a mixture of a primary hydrocarbon fuel comprising one or more alcohols; and dehydrating in the mixture the one or more alcohol to its or their corresponding ether and water, to obtain the compression ignition fuel.

Abstract: A compression ignition fuel composition comprising diethyl ether (DEE) and water, in amounts that correspond to the reaction product of dehydration of anhydrous or hydrous ethanol (EtOH) with water content between 0 and 30 wt %, and further characterized by: a) a diethyl ether content in wt % that is larger than or equal to 50, and a water content in wt % that is lower than or equal to 50 minus concentration of ethanol in wt % for mixtures containing 0 to 20 wt % ethanol; or b) a diethyl ether content in wt % that is larger than or equal to 54 minus 0.2 times the ethanol concentration in wt %, and a water content in wt % that is lower than or equal to 46 minus the 0.8 times concentration of ethanol in wt % for mixtures containing 20 to 30 wt % ethanol; or c) a diethyl ether content in wt % that is larger than or equal to 61.5 minus 0.45 times the ethanol concentration in wt %, and a water content in wt % that is lower than or equal to 38.5 minus the 0.

Abstract: Process for the synthesis of hydrocarbon constituents of gasoline comprising catalytic conversion in a gasoline synthesis step of an oxygenate-containing feed comprising methanol and/or dimethyl ether and a mixture of at least on a total oxygenate basis 0.05 wt % C3+ higher alcohols and/or their oxygenate equivalents to hydrocarbon constituents of gasoline.

Abstract: A process for the conversion of oxygenates to hydrocarbons comprising contacting a feed stream comprising oxygenates with a catalyst containing a microporous material under oxygenate conversion conditions, wherein the catalyst contains a crystalline microporous material with intra-crystalline mesopores. The invention also includes a composition for use in the above process.
