Abstract: The present disclosure provides a honeycomb catalyst for catalytic oxidative degradation of VOCs prepared by an ultrasonic double-atomization process. The honeycomb catalyst is prepared by performing acidification and performing hydrothermal activation in alcoholic solution for honeycomb to modify a surface; dissolving soluble transition metal inorganic salt in deionized water to obtain precursor solution; performing ultrasonic atomization of the precursor solution and the precipitant solution in the ultrasonic atomization device into droplets; placing the modified honeycomb in a special quartz glass reactor, wherein the droplets enter into the quartz glass reactor through a pipeline to come into contact with a surface of a honeycomb hole and rapidly react to generate a hydroxide precursor on the surface of the honeycomb hole; drying the honeycomb into a drying box after performing the ultrasonic atomization, and calcining the honeycomb into a muffle furnace to obtain the honeycomb catalyst loaded with transition metal oxides.

Abstract: Provided is a method for manufacturing a catalyst with which it is possible to obtain a supported metal ammonia synthesis catalyst, in which there are restrictions in terms of producing method and producing facility, and particularly large restrictions for industrial-scale producing, in a more simple manner and so that the obtained catalyst has a high activity. This method for manufacturing an ammonia synthesis catalyst includes: a first step for preparing 12CaO·7Al2O3 having a specific surface area of 5 m2/g or above; a second step for supporting a ruthenium compound on the 12CaO·7Al2O3; and a third step for performing a reduction process on the 12CaO·7Al2O3 supporting the ruthenium compound, obtained in the second step. This invention is characterized in that the reduction process is performed until the average particle diameter of the ruthenium after the reduction process has increased by at least 15% in relation to the average particle diameter of the ruthenium before the reduction process.

Abstract: A process for converting a hydrocarbon feed may comprise contacting a hydrocarbon feed with steam in the presence of a cracking catalyst under steam enhanced catalytic cracking conditions. The contacting the hydrocarbon feed with the steam in the presence of the cracking catalyst may cause at least a portion of the hydrocarbon feed to undergo steam catalytic cracking reactions to produce a cracked effluent comprising C2 to C4 olefins, C6 to C10 aromatic compounds, or both. The cracking catalyst may be a nanoparticle comprising: a core and a shell. The core may comprise one or more ZSM-5 zeolite particles and have an outer surface. The shell may comprise a plurality of fibers extending radially outward from the outer surface of the core. The plurality of fibers may comprise silica.
