The invention discloses a biomass carbon preparation process, and relates to the technical field of biomass carbon preparation. The biomass carbon is obtained by carbonizing crop straw and other biomass at low temperature, then carboxylating and then grafting with iron oxide and graphene oxide coated with nano-Al2O3 on the surface. The biomass carbon of the invention can be applied in the field of coal chemical industry, and can replace coal in the preparation of synthesis gas, which has great advantages in reducing carbon dioxide emissions. The biomass carbon of the invention has excellent adsorption and removal performance for organic pollutants, good acid resistance and high temperature resistance, and high environmental protection. Therefore, the biomass carbon of the invention is widely used in the field of coal chemical industry and wastewater treatment, which provides the possibility for the diversified utilization of biomass and is worthy of promotion.

The invention discloses an LNG (Liquefied Natural Gas) fuel supply system for a super-large box ship, which is applied to the field of engine fuel supply and is characterized in that an air temperature gasifier and a water bath gasifier are arranged in series to realize two-stage gasification treatment on LNG, so that the risk that ungasified LNG damages a downstream pipeline is reduced, meanwhile, environmental heat energy is preferentially utilized, and water bath heating is supplemented only when needed, so that the energy consumption is reduced, and the energy consumption is reduced. The operation energy consumption is obviously reduced; meanwhile, the electric heating pipe is used for assisting gasification in the engine starting stage, and the stable operation stage is switched to cylinder sleeve circulating hot water heating, so that the gasification reliability under different working conditions is guaranteed; in addition, the system further seals a pipeline valve and a flange through a sealing box, environmental moisture contact is reduced, the risks of icing of the outer walls of a connector and the valve, jamming of moving parts and sealing performance reduction are reduced, humidity in the box is reduced in cooperation with a dehumidifier, airflow is guided to flow circularly through a partition plate, and the dehumidification efficiency and the anti-freezing effect are further improved.
