Provided is a method for the preparation of a metal lattice-doping catalyst in an amorphous molten state, and the process of catalyzing methane to make olefins, aromatics, and hydrogen using the catalyst under oxygen-free, continuous flowing conditions. Such a process has little coke deposition and realizes atom-economic conversion. Under the conditions encountered in a fixed bed reactor (i.e. reaction temperature: 7501200 C.; reaction pressure: atmospheric pressure; the weight hourly space velocity of feed gas: 100030000 ml/g/h; and fixed bed), conversion of methane is 8-50%. The selectivity of olefins is 3090%. And selectivity of aromatics is 1070%. There is no coking. The reaction process has many advantages, including a long catalyst life (>100 hrs), high stability of redox and hydrothermal properties under high temperature, high selectivity towards target products, zero coke deposition, easy separation of products, good reproducibility, safe and reliable operation, etc., all of which are very desirable for industrial application.

The invention relates to a catalyst composition comprising a mixed oxide of vanadium, titanium, and phosphorus modified with alkali metal. The titanium component is derived from a water-soluble, redox-active organo-titanium compound. The catalyst composition is highly effective at facilitating the vapor-phase condensation of formaldehyde with acetic acid to generate acrylic acid, particularly using an industrially relevant aqueous liquid feed.

The catalyst has a microporous zeolite coating layer, and thus enables only gaseous products (light) to selectively pass through the zeolite coating layer, improving selectivity for 1,3-butadiene.

In response to the demand for shape-controlled metal microparticles accompanying rapid development and progress in industry in recent years, metal microparticles, which have projections on the surfaces of the particles that are integrated with the particles, are provided. The metal microparticles have integrated conical projections on the surfaces of the particles, and at least some of the projections are more than ? of the size of the particles. The protrusions that protrude from the metal microparticles melt and deform at a temperature lower than the melting point of the metal itself.
