摘要:
This invention relates to the production of dewaxed and/or hydroisomerized fuel composition that includes a step of hydrotreating a feedstock containing the lipidic material. The fuel compositions are high quality fuel compositions in which the fuel can be ultimately tailored for a variety of end uses such as jet fuel or diesel fuel.
摘要:
An integrated process for producing diesel fuel from feedstocks, including diesel fuel production under sour conditions, is provided. The ability to process feedstocks under higher sulfur and/or nitrogen conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. In addition to the benefits in sour service, the process also returns to clean service activity levels more quickly.

An improved dolly system including at least three dollies adjustably interconnected as a system to allow a trailer or other vehicle to be loaded therein. The dollies are adjusted for the width and the length of the trailer to mate the dollies with the wheels of the trailer. Four dollies can be adjustably connected in a system to provide a vehicle dolly system. The system can include one or more brakes and once loaded the system can be moved in any direction to facilitate the maximum use of available parking space.
摘要:
A cost effective method for reutilizing exiting refinery equipment associated with either a Reformer Unit or Isomerization Unit by converting such units into units and associated processes for hydrodesulfurizing and cracking naphtha feedstocks into light plant gases and chemical feedstocks. These existing Reformer or Isomerization units and processes can be converted into the processes described herein with very little capital expenditures, essentially utilizing almost all of the existing unit equipment, and with little to no major equipment replacements. The processes disclosed herein also effectively reduce the overproduction of naphtha currently experienced in many modern refineries that have resulted from a reduction in overall demand of gasoline products relative to other refinery products.

Non-hydrotreated biocomponent feeds can be mixed with mineral feeds and processed under catalytic isomerization/dewaxing conditions. The catalytic isomerization/dewaxing conditions can be selected to advantageously also substantially deoxygenate the mixed feed. Diesel fuel products with improved cold flow properties can be produced.
摘要:
A catalytic naphtha hydrodesulfurization process is operated in a process unit having a surge drum with equipped for gas blanketing with a blanketing gas containing controlled levels of CO and CO2. If the gas selected for blanketing normally contains more than the acceptable level of these inhibitors, they should be reduced to the levels appropriate for retention of catalyst functionality.
摘要:
A method for producing diesel fuel from biocomponent feeds includes hydrotreating the feed followed by catalytic dewaxing with a ZSM-48 containing catalyst. The hydrotreated feed may be cascaded directly to the dewaxing step, or the hydrotreated feed can undergo intermediate separation. The diesel fuel resulting from processing of the biocomponent feed exhibits superior cetane values.
摘要:
Methods are provided for hydrotreating high nitrogen feeds with improved results for nitrogen removal, aromatic saturation, and/or sulfur removal. The method includes hydrotreating the feed with a supported hydrotreating catalyst followed by a bulk metal catalyst, the hydrotreated effluent of which can be suitable for use as a feed to an FCC reactor.
摘要:
Systems and methods are provided for characterizing kerosene fractions in order to determine whether the fractions will satisfy a desired thermal breakpoint specification. Additionally, hydrotreating conditions can be determined that will result in a hydrotreated kerosene fraction that satisfies the desired thermal breakpoint specification. The hydrotreating conditions can be determined based on a model constructed from data corresponding to a plurality of reference samples. The model can include data for compositional groups within the reference samples. The data for compositional groups can be derived from Fourier transform ion cyclotron resonance mass spectrometry data or from another suitable characterization technique.
摘要:
This invention relates to a method for processing oxygenated hydrocarbons to form a hydroisomerized and/or dewaxed hydrocarbon product having a reduced oxygen content, an increased iso-paraffin content, a low n-paraffin content, and good cold flow properties. Advantageously, the method can utilize a zeolitic base catalyst, optionally but preferably containing at least one activated metal component, and a hydrothermally-stable binder such as titania.
