Since China announced its goal of becoming carbon-neutral by 2060, carbon neutrality has become a major target in the development of China's urban agglomerations. This study applied the Future Land Use Simulation(FLUS) model to predict the land use pattern of the ecological space of the Beibu Gulf urban agglomeration, in 2060 under ecological priority, agricultural priority and urbanized priority scenarios. The Integrated Valuation of Ecosystem Services and Trade-offs(In VEST) model was employed to analyse the spatial changes in ecological space carbon storage in each scenario from 2020 to 2060. Then, this study used a Geographically Weighted Regression(GWR) model to determine the main driving factors that influence the changes in land carbon sinking capacity. The results of the study can be summarised as follows: firstly, the agricultural and ecological priority scenarios will achieve balanced urban expansion and environmental protection of resources in an ecological space. The urbanized priority scenario will reduce the carbon sinking capacity. Among the simulation scenarios for 2060, carbon storage in the urbanized priority scenario will decrease by 112.26 × 10^(6) t compared with that for 2020 and the average carbon density will decrease by 0.96 kg/m^(2) compared with that for 2020. Carbon storage in the agricultural priority scenario will increase by 84.11 × 10^(6) t, and the average carbon density will decrease by 0.72 kg/m^(2). Carbon storage in the ecological priority scenario will increase by 3.03 × 10^(6) t, and the average carbon density will increase by 0.03 kg/m^(2). Under the premise that the population of the town will increases continuously, the ecological priority development approach may be a wise choice.Secondly, slope, distance to river and elevation are the most important factors that influence the carbon sink pattern of the ecological space in the Beibu Gulf urban agglomeration, followed by GDP, population density, slope direction and distance to traffic infrastructure.At the same time, urba

Hydrodearomatization Kinetics of Diesel Fraction and Catalyst Stacking Simulation

China Petroleum Processing & Petrochemical Technology 2022年第3期24卷 105-116页

作者： Wei Ye Sun Xinge LüHailong jiang hongbo Chen Wenbin Qin Kang Li Mingfeng Nie Hong Petroleum Processing Institute East China University of Science and TechnologyShanghai 200237China SINOPEC Research Institute of Petroleum Processing Beijing 100083China

The kinetics of hydrodearomatization (HDA) is studied in an isothermal high-throughput reactor over three catalysts (CoMo, NiMo, and NiMoW) to produce clean diesel fuel according to China’s latest emission standards. The influences of reaction temperature, pressure, the ratio of H2 to oil, and space time were systematically investigated. By analyzing the reaction mechanism, a four-lump kinetic model considering the influence of competitive adsorption was proposed for the hydrodearomatization reaction, and the model parameters were optimized with good fitting. It was found that nitrogen compounds inhibited the hydrodearomatization reaction. The simulation of various catalyst stacking schemes based on the HDA kinetic model is close to the experimental data, proving the reliability of the model. The concentration of aromatic compounds of different loading sequences was predicted with the catalyst gradation model.

Flow Field Simulation on Double-Ring Radial Flow Reactor

China Petroleum Processing & Petrochemical Technology 2017年第2期19卷 104-113页

作者： jiang hongbo Liang Yanhua Petroleum Processing Institute East China University of Science and Technology Shanghai 200237

Compared with the traditional radial flow reactors(RFRs), the double-ring RFRs possess advantages including lower pressure drop, shorter flow path and greater flow area. According to the Ergun's equation and the continuity equation, a two-dimensional hydrodynamic model was established to describe the hydrodynamic behavior in the double-ring RFRs. The successive over-relaxation(SOR) method was applied to solve the two-dimensional hydrodynamic model. The flow assignment parameters(T_i) of mass flow in the inner channel to the outer catalyst bed and the inner catalyst bed were optimized by the Powell method. Simulations showed the trend of change in gas distribution uniformity along the axial direction and the weight hourly space velocity(WHSV) with the variation of reactor size. The model can be used to analyze the reasonability of dehydrogenation reactor design, and it can also provide quantitative reference for the design of new double-ring RFRs.

China Petroleum Processing & Petrochemical Technology 2021年第3期23卷 90-103页

Ltd.Beijing 100007

An approach for the simulation and optimization of continuous catalyst-regenerative process of reforming is proposed in this paper.Compared to traditional method such as finite difference method,the orthogonal collocation method is less time-consuming and more accurate,which can meet the requirement of real-time optimization(RTO).In this paper,the equation-oriented method combined with the orthogonal collocation method and the finite difference method is adopted to build the RTO model for catalytic reforming regenerator.The orthogonal collocation method was adopted to discretize the differential equations and sequential quadratic programming(SQP)algorithm was used to solve the algebraic equations.The rate constants,active energy and reaction order were estimated,with the sum of relative errors between actual value and simulated value serving as optimization objective function.The model can quickly predict the fields of component concentration,temperature and pressure inside the regenerator under different conditions,as well as the real-time optimized conditions for industrial reforming regenerator.

Effect of Food on Specific Dynamic Action(SDA) of Green and Red Types of Sea Cucumber(Apostichopus japonicus Selenka)

Journal of Ocean University of China 2017年第5期16卷 905-910页

作者： BAO Jie jiang hongbo DONG Shuanglin TIAN Xiangli Key Laboratory of Mariculture of Ministry of Education Ocean University of China College of Animal Science and Veterinary Medicine Shenyang Agricultural University

Specific dynamic action(SDA), the energy expended on all physiological processes that is associated with meal digestion and absorption, is strongly affected by food type. Effects of formulated diet(FMD), macroalgae(ALG) and sea mud(SMD) diets on the postprandial metabolic response of the green type and the red type of sea cucumber(Apostichopus japonicus) were studied in order to understand their feeding physiology. Food offered to A. japonicus was different in protein, lipid content and energy but not in meal mass. SDA of A. japonicus resulted in a 1.3–2.7 folds of increase in oxygen consumption that can persist for up to 4.8–31.7 h after digesting three different diets. In a given type of sea cucumber, the magnitude of SDA was the highest when fed with FMD, medium with ALG, and the lowest with SMD, which is probably due to the differences in diet components and protein contents. The red type sea cucumber showed greater SDA magnitude than the green type with each diet treatment, which might result from the difference in factorial scope between the two types of sea cucumber. However, the smallest magnitude or even no difference was observed between the two types of A. japonicus in SMD group, perhaps owing to the poor nutrition and digestion of sea mud.
