    Abstract: The invention relates to a method for producing 1,3 butadien by means of the oxidative dehydration of n-butenes on a heterogenous particulate multimetal oxide catalyst which contains molybdenum as the active compound and at least one other metal and which is filled into the contact tubes (KR) of two or more tube bundle reactors (R-I, R-II), wherein a heat transfer medium flows around the intermediate space between the contact tubes (KR) of the two or more tube bundle reactors (R-I, R-II). The method includes a production mode and a regeneration mode which are carried out in an alternating manner. In the production mode, an n-butene-containing feed flow is mixed with an oxygen-containing gas flow and conducted as a supply flow (1) over the heterogenous particulate multimetal oxide catalyst filled into the contact tubes (KR) of the two or more tube bundle reactors (R-I, R-II), and the heat transfer medium absorbs the released reaction heat, minus the heat quantity used to heat the supply flow (1) to the reaction temperature in the production mode, by means of an indirect heat exchange and completely or partly dispenses the reaction heat onto a secondary heat transfer medium (H2Oliq) in an external cooler (SBK). In the regeneration mode, the heterogenous particulate multimetal oxide catalyst is regenerated by conducting an oxygen-containing gas mixture (3) over the catalyst and burning off the deposits accumulated on the heterogenous particulate multimetal oxide catalyst. The invention is characterized in that the two or more tube bundle reactors (R-I, R-II) have a single heat transfer medium circuit and as many of the two or more tube bundle reactors (R-I, R-II) as necessary are operated constantly in the production mode so that the released reaction heat, minus the heat quantity used to heat the supply flow (1) to the reaction temperature in the production mode, suffices to keep the temperature of the heat transfer medium in the intermediate spaces between the content tubes (KR) of all the tube bundle reactors (R-I, R-II) at a constant level with a variation range of maximally +/−10 DEG C.

    Abstract: A method for producing a hydrogen gaseous fuel from kinetic and/or potential energy recovered from a vehicle powered by a four stroke Diesel engine fitted with a Jacobs engine brake during a deceleration stage. Such a method comprises the following steps: a) providing a preheated steam flow; b) providing a gas flow from at least one chemical species used as preheated carbon and hydrogen source; c) mixing the gas flow from at least one chemical species used as carbon and hydrogen source from step a) with the steam flow from step b); d) reacting the mixture from step c) in the catalytic bed of a reforming reactor, heated by high temperature air from the compression stage of the Diesel engine acting as engine brake upon deceleration, producing an outlet synthesis gas flow which contains hydrogen; e) causing water to condense in the outlet synthesis gas flow which contains hydrogen, producing a water-free synthesis gas flow, and f) storing the synthesis gas flow obtained at step e) in a reservoir for its subsequent use during an acceleration stage of the vehicle. A system useful to implement the method for recovering kinetic and/or potential energy from a vehicle powered by a four stroke Diesel engine fitted with a Jacobs engine brake during a deceleration stage.
