Progress in Energy & Fuels, Vol.1, No.1, 2019; 94 Views, 4 PDF Downloads
In order to overcome the problems of chloride ion loss and corrosion of equipment in conventional alumina reforming catalysts, Ce3+ modified L molecular sieves were prepared by ion exchange method, and Pt/CeL reforming catalysts were prepared by impregnation method; XRD, the carrier and catalyst were characterized by N2 adsorption-desorption, NH3-TPD and Py-FTIR. The industrial refined naphtha with sulfur content of 0.50μg/mL was used as raw material to evaluate on the fixed bed microreactor. The reforming aromatization performance of the Pt/CeL catalyst. The results show that Ce3+ ion exchange can increase the acidity and acid strength of the carrier without destroying the skeleton structure of the L molecular sieve. The reforming aromatization performance of the Ce3+ modified Pt/CeL catalyst is obviously improved, and the activity and selectivity are achieved. The level of the alumina type commercial reforming catalyst indicates that the appropriate acidity has a significant effect on the aromatization reaction of the reforming catalyst.

Effects of Low Temperature Hydrothermal Pretreatment on N Distribution and Pyrolysis Characteristics of Chlorella pyrenoidosa Residue with High Protein Contentby Yinghua He
Progress in Energy & Fuels, Vol.1, No.1, 2019; 88 Views, 2 PDF Downloads
The hydrothermal degradation characteristics of high-protein chlorella in low-temperature hydrothermal pretreatment were studied by hydrothermal kettle. The product yield, elemental composition, energy recovery and key elements C and N of 125-200 °C were investigated. The results show that a large amount of C and N elements are enriched in the aqueous phase, and increasing the temperature (>175 °C) is beneficial to the deamination reaction and thus the relative content of NH3 in the aqueous phase. As the pretreatment temperature increases, the distribution of N in the oil phase product increases gradually and increases rapidly after 175 °C; the solid phase yield and energy recovery rate gradually decrease, but at the same time, its N/C and O/C also decrease, indicating Hydrothermal pretreatment is a upgrading process. The functional group structure and thermal degradation characteristics of the raw materials and algae residue were analyzed by FT-IR, XPS, TG-FTIR-MS and Py-GC-MS. The results show that the hydrothermal pretreatment process changes the relative content of different functional groups of C and N. Compared with the raw materials, the relative content of CC in algae residue increases, while the relative content of C-N and C-O decreases. In addition to protein-N and Quaternary amine-N, a small amount of pyridine-N appeared in the algal residue after pretreatment. The content and structural changes of the functional components of the solid algae residue reduce the release of NH3 and HCN in the thermogravimetric process and the content of the N-containing heterocyclic compound in the rapid pyrolysis product.

Coke Quality Prediction Model Based on Coking Coal Group Composition and Structural Parameters and Its Coke Forming Mechanismby Weimao Song
Progress in Energy & Fuels, Vol.1, No.1, 2019; 91 Views, 7 PDF Downloads
Taking five kinds of coking coal and 44 sets of coal blending as the research object, the coal cup coking experiment was completed in a 40kg small coke oven environment, and the coal heavy group, dense medium group and sparse coal obtained by separating the whole components of coal were obtained. The mass fraction YHC, YDMC, YLMC and the infrared spectral parameters I3 and I4 reflecting the hydrogen bond association and the length of the aliphatic chain or the degree of branching were the main indicators. The BP neural network analysis method was used to establish the coke quality prediction model. And discussed the characteristics of the model, and analyzed the coke formation mechanism under the new model. The results show that using new coal composition parameters to predict coke quality has certain advantages, and the predicted values (CSR), micro-strength (MSI), coke reactivity (PRI) and post-reaction strength (PSR) are measured and measured. The values are well consistent, and the fitting correlation coefficients for y=x are 0.986, 0.982, 0.956, and 0.926, respectively. The model has a good predictive effect on CR, MSI and PRI. The average deviation of the nine predicted samples is 0.53%, 1.58% and 1.28%, respectively. However, the PSR prediction effect after the reaction is poor, the average deviation At 12.22%. The research results provide a good basis for establishing a new method of coking coal blending.

Preparation of Ionic Liquid Supported Metal Frame Py/MOF-199 and Its Adsorption Desulfurization Performanceby Xinghe Zhu
Progress in Energy & Fuels, Vol.1, No.1, 2019; 100 Views, 4 PDF Downloads
The metal framework MOF-199 (Cu-BTC) was prepared and the [Hnmp][H2PO4] ionic liquid was loaded onto MOF-199 to synthesize the ionic liquid supported metal framework Py/MOF-199. The adsorbent was characterized by X-ray diffraction, infrared spectroscopy, scanning electron microscopy and specific surface area. The effects of pretreatment conditions of MOF-199, ionic liquid loading mode, loading, load temperature and loading time on the adsorption and removal performance of thiophene were investigated. The preparation conditions and adsorption desulfurization conditions of the adsorbent were optimized by orthogonal experiment. The results show that Py/MOF-199 obtained by ionic liquid modification maintains the regular octahedral structure of MOF-199. The suitable preparation conditions for Py/MOF-199 are as follows: pretreatment of MOF-199 by vacuum Soxhlet extraction and vacuum drying, followed by solvothermal loading [Hnmp][H2PO4], load temperature of 50 ° C, load The time is 8h and the load is 7%. The order of influence of various factors on the desulfurization performance of the adsorbent is: load temperature>loading time>ionic liquid loading. Suitable Py/MOF-199 adsorption desulfurization conditions are: simulated oil is 10mL, adsorbent dosage is 0.2g, adsorption temperature is 70 °C, adsorption time is 1h. Under these conditions, the thiophene removal rate can reach 96.7%.
