摘要： An exhaust heat recovery system 25 provided with a plurality of heat pipes 60, 61 provided with heat recovery parts 60a, 61a and heat exchange parts 60b, 61b. The heat pipes recover heat from exhaust gas exhausted from an internal combustion engine at the heat recovery parts and transfer this recovered heat to an object to be heated at the heat exchange parts. The heat recovery part 60a of the first heat pipe 60 recovers heat from the exhaust gas at an exhaust purification catalyst 20′ provided in an engine exhaust passage or its upstream side. The heat recovery part 61b of the second heat pipe 61 recovers heat from the exhaust gas at the downstream side of the exhaust purification catalyst. Due to this, there is provided an exhaust heat recovery system which can recover at least a fixed amount of exhaust heat at all times while maintaining a warm-up performance of the exhaust purification catalyst.

摘要： A distillate fuel feed is hydrotreated to remove heteroatoms and then separated into light and heavy hydrotreated fractions, with the heavy fraction catalytically dewaxed to improve low temperature properties. The hydrotreating and dewaxing are conducted in separate stages, which may be in the same reactor vessel. Fresh hydrogen may be passed into the dewaxing stage, with the dewaxing stage gaseous effluent then passed into the hydrotreating stage to provide hydrogen for the hydrotreating. Existing hydrotreating reaction vessels and facilities may be retrofitted to add one or more dewaxing stages.

摘要： The invention is directed to a bypass device for extending the operating life of fixed bed reactors. The device may be placed within a fixed catalyst bed to partition the bed into a first top bed and a second virtual bed. The bypass device allows any fluid feedstock to bypass the first top bed of the fixed catalyst bed as it fouls and enter the second virtual bed under conditions that promote depositing any foulants contained in the bypass flow on the top surface of the second virtual bed rather than in the interstices of the second virtual bed. The invention also relates to an improved fixed bed reactor comprising the inventive bypass device and a method for extending the operating life of a fixed bed reactor that employs the inventive bypass device.

摘要： A hydroprocessing process includes a cocurrent flow liquid reaction stage, a countercurrent flow liquid reaction stage and a vapor reaction stage in which feed components are catalytically hydroprocessed by reacting with hydrogen. Both liquid stages both produce a liquid and a vapor effluent, with the cocurrent stage liquid effluent the feed for the countercurrent stage and the countercurrent stage liquid effluent the hydroprocessed product liquid. Both liquid stage vapor effluents are combined and catalytically reacted with hydrogen in a vapor reaction stage, to form a hydroprocessed vapor. This vapor is cooled to condense and recover a portion of the hydroprocessed hydrocarbonaceous vapor components as additional product liquid. The uncondensed vapor is rich in hydrogen and is cleaned up if necessary, to remove contaminants, and then recycled back into the cocurrent stage as hydrogen-containing treat gas. Fresh hydrogen is introduced into the countercurrent stage and the countercurrent stage effluent contains sufficient, and preferably all of the hydrogen for the vapor stage reaction.

摘要： Disclosed is a catalytic cracking process that includes more than one catalytic cracking reaction step. The process integrates catalytic cracking steps with hydroprocessing in order to maximize olefins production, distillate quality and octane level of the overall cracked product. Preferably, one hydroprocessing step is included between the cat cracking reaction steps, and a portion of the hydroprocessed products, i.e., a naphtha and mid distillate fraction, is combined with cracked product for further separation and hydroprocessing. It is also preferred that the first catalytic cracking reaction step be a short contact time reaction step.
