The present invention discloses a method for making gas -producing briquette coal by using powdered coal. It is made up by using powdered coal, starch paste or starch residue paste, MSG-1303 type plasticizing agent or aluminium magnesium silicate binder, and making them pass through such procedures of uniformly mixing, press-molding and drying. The water content of said briquette coal is 12-18%, and the weight of MSG-1303 type plasticizing agent or aluminium magnesium silicate binder is 5-12% and the weight of starch paste or starch residue paste dry base is 1-5% of that of powdered coal respectively. The cold-strength of the briquette coal produced by using said process is 68 kg/briquet, its hot-strength is 15 kg/briquet, and its thermal stability is 80%, and after having been soaked in water for 4 h. it doesn't loose.

The present invention relates to a hydrocarbon conversion catalyst for producing C<=>3 and C<=>4 and gasoline with high quality, which is composed of three kinds of zeolites, namely ZSM-5, REY and high-silicon Y as active ingredients and fully-synthetic carriers or semi-synthetic carriers as the rest, wherein the weight of the zeolites is 10 to 40% of that of the catalyst, the semi-synthetic carriers contain 10 to 40 wt% of silicon and/or aluminium adhesive, the ZSM-5 is 3 to 50 wt% of the active ingredients, and the REY and the high-silicon Y are respectively 12 to 75 wt% of the active ingredients. The catalyst is suitable for the conversion of petroleum distillate, residual oil or crude oil with different boiling ranges. The yield of C<=>3 and C<=>4 is from 20 to 30 wt%, the yield of C<+>5 gasoline is from 40 to 55 wt%, the yield of RON is from 91 to 95 wt%, and an induction period is from 500 to 1000 minutes.
