A sand aggregate includes plural aggregate grains, wherein at least one aggregate grain of the plural aggregate grains includes, desert sand grains that are too small to be used in concrete applications, carbonate particles distributed on an external surface of the desert sand grains, and a sand-based glue that aggregates the desert sand grains together. The at least one aggregate grain has a size comparable to river sand grains, while the desert sand grains have a size smaller than the river sand grains so that the at least one aggregate grain is suitable for concrete applications.

A method for making a metal carbide based catalyst for crude oil cracking includes mixing a clay with a phosphorous based stabilizer material to obtain a liquid slurry; adding an aluminosilicate zeolite and an ultrastable Y zeolite to the liquid slurry; adding AlCl(OH)to the liquid slurry; adding metal carbide particles, having a given diameter, to the liquid slurry to obtain a mixture; and spray drying the mixture to obtain the metal carbide based catalyst. The metal carbide particles are coated with the aluminosilicate zeolite and the ultrastable Y zeolite.

Metal carbide based catalyst and method of making

A method for ammonia decomposition to produce hydrogen, the method comprising the steps of introducing an ammonia stream to a reactor, wherein the ammonia stream comprises ammonia, wherein the reactor comprises a cobalt-based catalyst, the cobalt-based catalyst comprising 15 wt % and 70 wt % of cobalt, 5 wt % and 45 wt % of cerium, and 0.4 wt % and 0.5 wt % barium, wherein a remainder of weight of the cobalt-based catalyst is oxygen; contacting the ammonia in the ammonia stream with the cobalt-based catalyst, wherein the cobalt-based catalyst is operable to catalyze an ammonia decomposition reaction; catalyzing the ammonia decomposition reaction to cause the ammonia decomposition in the presence of the cobalt-based catalyst to produce hydrogen; and withdrawing a product stream from the reactor, the product stream comprising hydrogen.
