世界炼油催化剂需求强劲增长

催化剂生产商面对成本压力一些炼油催化剂公司认为，为满足严格的环保法规而对催化剂需求增加，以及汽油需求增长，将使2006年的催化剂需求强劲增长。同时，预计至少在今后5年内炼油催化剂市场仍将呈增长态势。然而，原材料成本的上升，尤其是金属和天然气价格的上涨，使催化剂生产继续面临挑战。加氢催化剂生产商可将价格上涨转嫁给炼油商，但催化裂化催化剂公司将面临较大压力。对于加氢催化剂，所用助剂金属（钼、钴和镍）的价格飞快上涨。通常为11—13美元／kt的钼的价格，主要由于亚洲需求量大而上涨至2005年77美元／kt。由于加氢催化剂含有高达25％的钼，钼价格的大幅上调对催化剂价格影响很大。     

炼油催化剂：未来市场看好

由于燃油新标准的推行，炼油商使用重质、劣质原料的增多，以及炼油能力的扩展，2007年是炼油催化剂用量强劲增长的一年。FCC催化剂市场将从供过于求更趋于平衡，而加氢催化剂的供需将比2006年稍有吃紧。

全球炼油催化剂需求猛增

据美国《化学周刊》的最新报道，为了满足日趋严格的环保法规及不断增长的汽油需求，今年全球炼油催化剂业务迅速增长，未来5年还将继续保持较高的增速。不过，由于原材料成本不断升高，特别是金属和天然气价格增长较快，使得炼油催化剂业面临巨大挑战。预计加氢工艺催化剂生产商可以轻松渡过涨价关口，流化催化裂化催化剂企业则要面临较大压力。     

未来几年全球炼油催化剂市场前景看好

炼油催化剂公司表示，受新一轮低硫燃料标准实施、炼油商增加劣质原油加工量和新增炼油产能的影响，炼油催化剂业务正在强劲增长。据美国Freedonia集团分析师Ned Zimmerman的最新研究报告显示，未来几年全球炼油催化剂市场需求有望以年均2．8％的速度增长，到2010年全球炼油催化剂市场份额将达到35亿美元。若按消费量计算，全球炼油催化剂需求有望以年均2．1％的速度增长，到2010年的消费量将达到410万t。     

全球炼油催化剂使用将增长

<正>根据IHS化学公司分析,全球炼油催化剂市场2011年为31亿美元,约为125亿美元过程催化剂行业的1/4。按价值计,最大的细分市场是加氢催化剂,而用量最大的产品是沸石基FCC催化剂,它可使重质石油馏分转化成较轻质、更有价值的组分。其他重要的炼油催化剂市场领域,包括加氢裂化和重整催化剂。炼油企业正在越来越多地使用FCC渣油催化剂以使渣油改质并增加烯烃产量。随着炼制商增加加氢处理能力,以

Assisted Electrochemical Hydroconversion of Heterocompounds Present in Fuel and Oil Using Active Hydrogen Passing through a Pd Membrane

Abstract

The assisted electrochemical conversion of thiophenes, pyridines, porphyrins, and metalloporphyrins using active hydrogen passing through a Pd membrane is reported. This novel process has potential implications in the hydrotreating field, because relatively high conversions can be achieved for reactions performed under mild conditions (25°C and 1 atm), applying an optimum current density value to produce atomic hydrogen through the well-known water electrolysis process. Some applications are envisaged for this process still in embryonic phases: (1) the finishing process to produce ultra-low-sulfur fuels; (2) terminal hydrotreating, and (3) small or medium-sized refineries.

天然气的有效合理利用是目前的研究热点之一。甲烷的氧化偶联、部分氧化制合成气、甲烷制氢和芳烃等的研究工作对于由天然气生产液体燃料及化工基本原料的石油化工战略转移具有非常重要的学术和经济意义。但要同时得到甲烷活化的各类反应高活性、高选择性及高收率,单纯改进催化剂是难于达到的。在研究天然气催化活化的同时改进新设备、新技术、新方法和催化剂的协同作用,实施过程强化,有望为天然气活化利用提供新的途径。本文综述了这方面的研究进展,并展望了该领域的发展前景。     

Feeding Methanol in an FCC Unit

The feasibility analysis of integrating methanol to olefins (MTO) with fluidized catalytic cracking (FCC) process is based on their similarities and compatibility. Feeding methanol in FCC is proposed to produce more light olefins. According to the characters of FCC, the effects of reaction temperature, water co-feed, and the coke content of catalyst in methanol conversion were studied systematically. It is concluded that high light olefins yields from methanol conversion were obtained on the FCC condition. Feeding methanol in FCC at the bottom of riser as the proper position was suggested on the ground of comparison with MGD process of FCC. The research proved the feasibility of feeding methanol in FCC and provided important reference for its commercial application in a certain degree.     

Conversion of a Naphtha Reformer Unit to Butane Isomerization

A study was carried out for the conversion of a naphtha reformer unit to a butane isomerization plant, where a normal butane rich stream is isomerizated to isobutane. This compound has a bigger added value when it is used in an alkylation process to produce a high octane alkylated fuel, which is used as an adjustment component in high octane gasoline blending.

Basically the new isomerization unit will work with a conventional process scheme. Nevertheless, some adaptations in the loading preparation section are included in this study, in order to fit up the process load because its high light components content, specifically propane. An equipment pre-sizing and current equipment reusing analysis at the process condition specifications are also included. Technically, it is concluded that the conversion is feasible because most of the existing equipment can be used.

Finally, the analysis was complemented with an economic study in order to determinate the profitability of the existing plant conversion against the construction of a new one. Conversion resulted in being the most profitable option, requiring an investment equivalent to 70% from that corresponding for a new plant construction, with a 48.14 internal rate of return, and 1 year and 5 months investment recovery period.     

Prediction of dibenzothiophene conversion in the ultrasound assisted oxidative desulfurization process

In order to produce ultra-low sulfur diesel, ultrasound-assisted oxidation desulfurization of dibenzothiophene (DBT) was carried out with acetic acid and hydrogen peroxide. Due to its complexity, ultrasound-assisted oxidation process lacks a precise analytical solution. This paper explores the application of linear multiple regression and neural network for the prediction of dibenzothiophene conversion. Models were employed with respect to hydrogen peroxide dosage, temperature, reaction time, initial DBT concentration, and rate constant. The most accurate results were achieved by neural network model. Developed models facilitate future research in terms of better understanding the influence of process conditions of DBT conversion.
