OP-V-9sintering a couple of spiraled flat and corrugated strips. The dimensions of the monolithcatalyst are: diameter 55 mm, length 55 mm.Fig. 1 shows a schematic of the setup for tests of catalysts for the autothermal reformingof diesel fuel. The setup contains the following parts: a catalytic synthesis gas generator, anevaporator of a mixture of diesel fuel and water, an autothermal reformer, a catalytic burner, asystem of feeding and control and analytical equipment.Fig. 1. Scheme of the setup for tests of developed catalysts.For the autothermal diesel fuel reforming, we developed 6 catalyst composites based onthe reinforced gauze support. As follows from the experiments, the samples of monolithreinforced metal porous catalysts containing Ba, Co and Mn as an active component are themost promising for autothermal conversion of diesel fuel. The process of autothermalreforming of diesel fuel into syngas is not accompanied by coke formation for these catalysts.The most promising catalysts provide the yield of synthesis gas (Н 2 + CО) in the experimentalruns 2.88 l/g of diesel fuel at H 2 /CO=3.5 with more than 30 vol.% H 2 in the dry reformingproducts. The optimal conditions of autothermal reforming of diesel fuel are: О 2 /С =0.5-0.6,Н 2 О/C =1.5-1.7, contact time 0.3-0.4 s, temperature of mixture at the reactor inlet 300-400°C.The obtained solutions will be used in future developments of vehicle versions of the onboardsyngas generator in order to provide low pollutants emission in exhaust gas.References1.
