The heat preservation layer is arranged on the inner layer of the shielding layer, can slow down conduction of high temperature outside the cabinet body to the cabinet body by the plate and keeps the temperature of the cabinet body normal and stable; the fireproof layer arranged on the inner side of the interlayer can prevent spreading of a fire disaster happening in the cabinet body. The invention further discloses the power distribution cabinet adopting the plate.

A unique design for a mobile system that reforms flare gas or natural gas, using air without steam, to directly produce dimethyl ether (DME), a diesel substitute, is disclosed. The system first reforms the air-methane mixture at ambient atmospheric pressures, and then compresses the resulting CO-hydrogen-nitrogen gas mixture to up to 600 psi, and feeds it through a combined reactor which reacts the gas mixture directly into dimethyl ether. The nitrogen is returned by the system back to the atmosphere. DME is an excellent diesel fuel, and can be used to displace significantly costlier and dirtier petroleum-based diesel fuel, while solving a critical problem with flaring. For example, the over 120 billion cubic feet per year that is currently flared in North Dakota could be converted into over 3 million tons of DME.

A mobile system and method that reform flare gas, methane, or natural gas, using air without steam, to directly produce methanol, a clean burning gasoline blend, component, and / or substitute are disclosed. The system first reforms the air-methane mixture at ambient atmospheric pressure, then compresses the resulting CO-hydrogen-nitrogen gas mixture to 600 psi, and feeds it through a methanol reactor which reacts the gas mixture directly into methanol.
