Abstract: A method for preparing a high-quality fuel oil and/or chemical raw material from a biomass pyrolysis liquid. In the method, a biomass pyrolysis liquid undergoes a hydrodeoxygenation reaction in a catalyst full mixing flow circulation system in a fluidized bed reactor to obtain deoxygenated oil, and the obtained deoxygenated oil undergoes a hydrocracking reaction in a fixed bed reactor to obtain high-quality fuel oil and/or a chemical raw material. The method may prevent the condensation and coking of a biomass pyrolysis liquid, solve the problem of rapid catalyst deactivation, and may convert a biomass pyrolysis liquid into a high-quality fuel oil that may be directly used by vehicles and into a chemical product.

Abstract: A method and system are provided for acquiring the probability of slope failure and destabilization caused by an earthquake. For example, the method includes performing azimuth division in an area around a site at which a slope is located as a center, pre-setting a seismic acceleration threshold value that varies within a certain range, and calculating an exceeding probability that the seismic acceleration of the slope site generated by an earthquake in each azimuth domain is greater than or equal to the seismic acceleration threshold value, to establish an exceeding probability curve of site seismic acceleration corresponding to each azimuth domain. The method and system achieve estimation of the probability of slope destabilization caused by an earthquake by comprehensively considering the uncertainty of the seismic action and the uncertainty of slope failure and destabilization.
