Abstract: Disclosed are a special fertilizer for intercropping maize and peanuts and a cultivation method for maintaining soil organic carbon (SOC) balance, belonging to the technical field of SOC balance. The special fertilizer for intercropping maize and peanuts includes the following raw materials: coated urea, heavy superphosphate, ammonium sulfate, fermented soybean meal, bentonite, sodium molybdate, borax, humic acid, ammonium dihydrogen phosphate, plant ash and zinc sulfate heptahydrate. The cultivation method includes the steps of land selection, land preparation, fertilizing, sowing, field management, and rotation.

Abstract: A refractory wall comprises a hotface layer comprising a hotface surface configured to be adjacent to a carbonaceous gasification environment, a backing layer facing the hotface layer, and a cooling layer facing the backing layer and configured to cool the hotface layer via the backing layer. A gasification device and a gasification process are also presented.

Abstract: An injector for co-feeding liquid and solid fuels into a gasifier is provided. The injector includes a body, a first member, and a second member. The body comprises a first channel for conveying a liquid fuel. The first member surrounds the body to define a second channel for pneumatically conveying a solid fuel. The second member surrounds the first member to define a third channel for conveying a fluid stream for dispersing the solid fuel. The liquid fuel is atomized before being mixed with the solid fuel. A method for co-feeding liquid and solid fuels is also presented.
