20140034551FCC PROCESS FOR MAXIMIZING DIESEL - A process is described for maximizing the FCC middle distillates comprising the use of two different converters, operating in a coordinated manner that seeks to maximize the production of LCO for diesel, generating a specified gasoline and reducing fuel oil production. Converter “A” operates with a low contact time in the riser, of 0.2 to 1.5 sec. (preferably from 0.5 to 1.0 sec.) making a higher reaction temperature possible even at low severity, from 510° C. to 560° C. (preferably from 530° C. to 550° C.) and with a catalyst suitable to the maximization of LCO. Converter “B” possesses a high activity catalytic system, suited to cracking naphtha and DO generated in the first converter. Preferably, converter “B” has two separate risers, allowing the reaction temperatures of each to be adjusted independently according to the range most recommended for maximizing the cracking of each of the streams: 530° C. to 560° C. for the DO riser and 540° C. to 600° C. for the naphtha riser. The high-quality LCO stream generated by cracking at low severity in converter “A” is not contaminated by the poorer quality LCO generated by re-cracking the DO in converter “B,” since each converter has its own fractionating tower. The use of low contact time as a route for reducing severity in converter “A” geared towards the production of better quality LCO allows it to operate with a higher reaction temperature for the same LCO conversion and quality level, entailing greater operating reliability for the unit, and providing benefits for the heat balance of the converter. In existing units, the improvement in the heat balance provides leeway to the air blower via increased batch temperature, and makes room for processing more residual batches.02-06-2014
20150136647REACTOR AND MAIN FRACTIONATOR CONFIGURATION FOR PRODUCING DIESEL - Methods and systems. For producing diesel arc provided. The method for producing diesel can include cracking a first hydrocarbon feed in a first riser under first cracking conditions to provide a first effluent containing a first light cycle oil, a heavy cycle oil, and a first bottoms and Fractionating at least a portion of the first effluent to separate the first bottoms and the heavy cycle oil from the first light cycle oil. The method can include cracking the separated first bottoms in a second riser under second cracking conditions to produce a second effluent containing a second light cycle oil and a second bottoms. The method can also include cracking the separated heavy cycle oil in the first riser under third cracking conditions to provide a third effluent and mixing the third effluent with the first hydrocarbon feed to provide the first cracking conditions.05-21-2015
20150322354VAPOR PRESSURE ENHANCER - The present invention relates to a device that installs in-line in the fuel supply line of fuel usage equipment such as a HVAC system or a large commercial natural gas or diesel generator. The device is suitable for use with liquid or gas hydrocarbon fuels such as gasoline, diesel, propane, or natural gas. The device consists of a hollow cylinder with male ends and that contains a tightly packed copper wire core. The copper wire serves as a catalyst to crack the fuel's carbon chain molecules as the fuel flows through the device. The resulting fuel contains more and shorter fuel molecules, has a higher vapor pressure and burns more efficiently in the vehicle's engine. The copper wire is held in place by perforated copper keepers and the keepers are secured within the cylinder by snap rings that engage circumferential grooves provided internally at the ends of the cylinder.11-12-2015

A hydrocarbon material and a cracking material can be injected into separate injection ports of a nozzle reactor to produce a hydrocarbon product. The hydrocarbon product can be injected directly into a coker so that heavy hydrocarbon compounds can be upgraded into lighter hydrocarbon compounds, or the hydrocarbon product can first be injected into a separation vessel to separate hydrocarbons having higher boiling point temperature from hydrocarbons having lower boiling point temperature. The hydrocarbons having higher boiling point temperature can then be injected into a coker.11-14-2013
