A method for synthesis of MgH.sub.2/Ni nanocomposites includes balancing magnesium (Mg) powder in a ball milling container with helium (He) gas atmosphere; adding a plurality of nickel (Ni) milling balls to the container; introducing hydrogen (H.sub.2) gas to the container to form a MgH.sub.2 powder; milling the MgH.sub.2 powder using the Ni-balls as milling media to provide MgH.sub.2/Ni nanocomposites. The milling can be high-energy ball milling, e.g., under 50 bar of hydrogen gas atmosphere. The high-energy ball milling can be reactive ball milling (RBM). The method can be used to attach Ni to MgH.sub.2 powders to enhance the kinetics of hydrogenation/dehydrogenation of MgH.sub.2.

The invention relates to petroleum sludge or other wastes recycle treatment system, which comprises a pre-treatment operation facility for a treated matter to be treated as a raw material. A feeding unit is arranged to feed the raw material into at least one gasification reactor with a push rod or a screw for pyrolysis gasification. The upper half of the at least one gasification reactor is provided with a syngas collecting pipe which can be connected with a gas collecting pump, and the lower half is provided with a liquid petroleum output pipe and an ash residue outlet, in which the ash residue outlet can be provided with a spiral pipe to draw the ash residue out. The petroleum sludge and other wastes in a dense fluid state are transported from a raw material tank to the at least one gasification reactor end which is bent upward through at least one pipe body, and the feeding mode of pyrolysis gasification of the raw material from below to upper of the gasification reactor is adopted. The top of the at least one gasification reactor is provided with a syngas collecting pipe, and the other side is provided with an ash residue accumulation chamber. The ash residue can be centralized and discharged through the lower buffer chamber and the slag discharge chamber, so as to convert the petroleum sludge or other wastes into more energy-efficient syngas providing human beings as users of electric or thermal energy.

Differing from the startup temperature of partial oxidation of butane (POB) reaction stimulated by conventional rhodium-based or nickel-based catalyst reaches 700° C. or above, the present invention particularly discloses a novel catalyst consisting of fluorite-type oxide support and Ni active metal for being applied in hydrogen production by low temperature partial oxidation of light hydrocarbon (POLH), so as to effectively reduce the startup temperature of the POLH reaction. In the present invention, the said light hydrocarbon means methane, ethane, propane, or butane. Moreover, a variety of experimental data have proved that this novel catalyst makes the startup temperature of POB reactions be lowered to 250° C. On the other hand, the experimental data have also proved that, the carbon deposition formed on the catalyst during POB reaction can be obviously improved after adding a few amount of platinum into the constituting ingredients of the novel catalyst.

The present invention provides a porous coordination polymer, wherein the porous coordination polymer is formed of unit lattices; each of the unit lattices has a shape of a cube having eight vertexes and twelve sides; each of the vertexes of the unit lattices consists of a Zn.sub.4O cluster; each of the sides of the unit lattices consists of a .sup.−OOC—C≡C—COO.sup.− group. At least a part of the unit lattices contains at least one hydrogen molecule only, or the inside of at least a part of the unit lattices is empty. The present invention provides a novel porous coordination polymer, especially, a porous coordination polymer suitable for separating hydrogen molecules from a gaseous mixture of the hydrogen molecules and impurity molecules (e.g., nitrogen molecules, oxygen molecules, or carbon dioxide molecules).
