This application belongs to the technical field of aluminum-plastic door and window profiles, and discloses an aluminum-plastic door and window profile with enhanced wind pressure resistance, including a top plastic profile, a middle aluminum profile, and a bottom plastic profile. The bottom of the top plastic profile has a middle aluminum profile at its bottom, and the bottom plastic profile has a bottom plastic profile at its bottom. A support block is provided inside the top plastic profile, and the support block has several equidistantly distributed pressure-resistant grooves inside. A connecting component is provided between the top plastic profile and the middle aluminum profile, and a support component is provided between the middle aluminum profile and the bottom plastic profile. Baffles are provided on both sides of the top of the bottom plastic profile. This application enhances the connection strength between the top plastic profile and the middle aluminum profile by providing connecting components, and enhances the connection strength between the bottom plastic profile and the middle aluminum profile by providing support components, thereby improving the wind pressure resistance and strength of the aluminum-plastic door and window, and increasing the stability and service life of the door and window.

The present application relates to the technical field of steel metallurgy, and particularly relates to a method and system for coking of biomass tar in cooperation with coal blending. The method comprises the following steps: biomass tar grading pretreatment: sequentially performing pre-hydrogenation desulfurization, deoxidation and alkali removal on the biomass tar to obtain pretreated biomass tar; coal blending and coking: heating and coking the pretreated biomass tar mixed with base coal to obtain coke. The method solves the problem of poor coal blending compatibility caused by high viscosity and high oxygen and sulfur content of the biomass tar through "grading pretreatment-coal blending and coking-catalyst regeneration", and reduces the negative impact of alkali in the biomass tar on the strength of coke in the coking process.
