NOVELTY - High viscosity solid carbonaceous materials pyrolysis reactor system comprises carbonaceous material pyrolysis furnace (200) provided with carbon material and catalytic heat carrier inlet (210), a lifting gas inlet (202), a solid or liquid product and waste catalyzing heat carrier outlet (204), and gas or steam product outlet pipeline of pyrolysis unit (205), where at least one of which is located inside the opening of a downmixer (100).    USE - Reactor system used for pyrolysis of high viscosity solid carbonaceous material, particularly coal, coal direct liquefaction residuals, heavy residual oil, coke, petroleum coke, oil sand, oil shale, carbonaceous industrial wastes or ore, biomass synthetic plastic, synthetic polymers, waste tire, industrial waste, and/or asphalt (all claimed).    ADVANTAGE - The system provides fast mixing, high heat transfer rate, and accurate and uniform control of short residence time of fast pyrolysis of carbonaceous materials.    DETAILED DESCRIPTION - High viscosity solid carbonaceous materials pyrolysis reactor system comprises carbonaceous material pyrolysis furnace (200) provided with carbon material and catalytic heat carrier inlet (210), a lifting gas inlet (202), a solid or liquid product and waste catalyzing heat carrier outlet (204), and gas or steam product outlet pipeline (205) of pyrolysis unit, where at least one of which is located inside the opening of a downmixer (100). The carbon material and catalyzing heat carrier is forced in close contact and fully mixing so as to form the pyrolysis furnace to move downwards to the lower part of the carbon material and catalytic heat carrier mixture, where at the same time, the heat is quickly and uniformly transferred from the catalytic heat carrier to the carbonaceous material. The waste catalyzing heat carrier is separated from solid-solid separator (300) or solid-solution separator (400), and waste catalyzing heat carrier conveying pipeline (312, 407). Catalytic heat carrier conveying pipeline (102) is connected with pyrolysis furnace which is connected with catalytic heat carrier and heater (500). The solid or liquid product or exogenous fuel is introduced into the heat exchanger for thermal cracking. The re-heater has oxygen-containing stream so as to be re-heat the catalytic heat carrier that passes through the conveying pipeline and is recycled back to the downmixer, where there is no oxygen or fuel gas consumption from the re-heater. The gas or product outlet pipeline of pyrolysis and/or gas or product outlet pipeline is connected with pyrolysis furnace. A condenser is connected with the gas in the oil tar and condenses the liquid tar or oil and gas product of pyrolysis phase.
