The invention discloses a hot water boiler without flammable fuel, and relates to a water heating device. The hot water boiler comprises a base, a boiler body, a rotary shaft, a heating rotor, a bearing and a bearing gland, wherein the base is provided with the bearing; a water inlet cavity communicated with a water inlet and the interior of the boiler body is arranged among the boiler body, the bearing and the rotary shaft; a water decomposer is arranged in the water inlet cavity; the rotary shaft in the boiler body is provided with the heating rotor; the two end faces of the heating rotor are respectively provided with at least two heating rings at intervals; the heating rings are coaxial with hubs of the heating rotors and are not equal in diameter; the inner wall of the boiler body is provided with friction rings in inserted and embedded fit with the heating rings; a heating interval of 0.3-2.8 mm is formed between each friction ring and the corresponding heating ring; the side wall of the boiler body is provided with a water outlet. According to the hot water boiler, space is saved, management and maintenance are achieved without a lot of people, the heating speed and heating efficiency are high, energy sources are saved, cost for hot water processing is low, pollution to environment does not exist, maintenance is easy and convenient, and the hot water boiler is suitable for heating and processing hot water.

The present invention relates to biodiesel oil preparing process, and provides one biodiesel oil preparing process with solid acid and solid alkali as catalyst to lower the activating energy and raise the reaction speed. The biodiesel oil preparing process includes the following steps: reacting dried grease with high free fatty acid content, methanol or ethanol, and cosolvent in the molar ratio of 1 to 6-1 to 6.05 in the first fixed bed reactor with solid catalyst A at 60-65 deg.c for about 3 hr; separating the oil phase from others; reacting the oil phase in the second fixed bed reactor with solid catalyst B with methanol or ethanol and cosolvent at 60-65 deg.c for about 3 hr; distilling out methanol or ethanol and cosolvent; separating the biodiesel oil from glycerin phase; and distilling the biodiesel oil phase to obtain biodiesel oil product. The catalyst of the present invention has high catalytic activity and can lower the activating energy and raise the reaction speed.

The invention discloses a hydrotreatment and catalytic cracking combined method of a heavy hydrocarbon raw material. According to the invention, an upflow reactor is at least connected in series with a downflow fixed bed reactor. The heavy hydrocarbon raw material passes through UFR and is mixed with a catalytic cracking heavy fraction, and the mixture enters the downflow fixed bed reactor. A hydrogenation reaction effluent is separated so as to obtain a liquid phase, and the liquid phase is subjected to catalytic cracking. The obtained catalytic cracking heavy fraction returns to an inlet of the downflow fixed bed reactor. According to the method, the catalytic cracking heavy distillate oil, which is introduced into the inlet of the fixed bed reactor, is beneficial to hydrogenation reaction and can significantly improve temperature rising of the bed when used as cutback oil and can minimize the amount of hydrogen injected through the inlet when used as a hydrogen donor, thus further raising cooperative effect of combined flow equipment and prolonging the running period as well.
